Effects of Water Temperature on Plant Growth
Effects of urine Temperature on engraft GrowthAbstractTest the actuate of vaporize urine and boiled irrigate on positions. No major difference of the forms growth between boiled and atomise weewee, shown in the imparts.1.0 gate mienThe fol brokening look into was conducted over a period of 5 weeks testing 2 different instal species on the affects of nuke irrigate, behind the theory of microwave beam altering the chemical composition of water. establish upon this theory the plants were experimented to see if microwave radiation alters the structure of DNA affecting the growth of plants. Research Centre, 2006Two hydrogen atoms and one type O atom is the very simple atomic structure of water. Causing it to concord droll electrochemical properties. A slight positive charge on the hydrogen side of the jot, with a prohibit charge on the other side. piss is a powerful solvent and is responsible for its string muster up tension, as the molecular polarity causes wate r molecules to arrange themselves in patterns when a physical phase changes in water molecule. Specific arouse is the energy amount required to change the temperature of a substance and wast has advanced specialised heat. Large amount of heat energy, before it begins to get hot as its high specific heat. Helps organisms relate their body temperature as it releases energy slower and more effectively when caused to cool. Neither acid or basis with a neutral pH. The pH changes if substances argon dissolved in it. Good heat conductor, conducting well than any other liquid. Uniform vertical temperature profile for large bodies of water is due the easy heat conduction. With a temperature range of 0 to 100 Celsius, allows the water molecule to exist in most places near the world. Being able to dissolve many a(prenominal) different compounds and chemicals as its an universal solvent with a high surface tension. Adhesive, elastic and in aggregate drops is what water tends to be. Despi te the downward of gravity the phenomenon causes water to draw to the sides of vertical structures. It also allows waves and water droplet formation and for plants to move water dissolving nutrients from their roots to their leaves. Pidwirny, M. 2006.A gathering of living organism with some 300, 000 different species characterised by their green colour, are plants. Trees, herbs, flowers and ferns are some greenness groups of plants. Sprout, shedling is the meaning of planta a Latin word in which plant originated form. R, Conan-Davies. 2009 Each part of the plant plays a different role. Absorbing from the blot, water and minerals are the roots which act like straws. Extra food for the rising is stored and helps anchor the plant, the tiny root hairs assist in the nutrients absorption. Acting like the plumbing system for the plant and supporting it, is the stem. In the form of glucose water and nutrients is conducted from the leaves to different parts of the plant. Being either herbaceous and ductile or woody. The small stalk which attaches the click to the plants stem is called the petiole. The leaves are where majority of the plants food is made, through the lick of photosynthesis. The leaves are designed to capture sunshine for the photosynthesis process to work. The reproductive section of the plant is the flower. Pollen and ovules are contained in the flower, after the pollen fertilizes the ovule through pollination, fruit develops. Providing seed covering is the fruits role and is also edible to humans and animals. The seed is the basis of a plant. Botanical Garden, 2009 Carbon fixation and photosynthesis conducted by plans and algae is the energy and organic material cite in all habitats. The earths 20% composition is changed radically by the plants process. Internal energy which relies on oxygen to move and grow is aerobic organism such as animals. The nutrients of animal and humans rely firmly on plants. R, Conan-Davies. 2009Petunia is scien tifically known as Petunia x hybrida. NC State University, 2010 popular low lying annuals provide a brilliant display and attr lively colours and green foliage in garden do its or containers. Blooming all summer long. Growing best in bounteous sunlight with soil the is peat based which contains vermiculite. Petunias will survive in the shade that at least 6 hours of full sunlight daily. With ranging colours from whites to yellows, petunias can be the main attraction in a garden bed with minimal maintenance. There are several varieties of petunias. Water the plants pior to planting them and allow for d rainfallage. Fertilising with a liquid fertiliser or soluble on every two weeks will help keep plants healthy. Garden Guides, 2010 information pegCalendula officinalis is ordinarily known as the marigold. Eco India, 2008 Easy to grow and provide bright large displays in the garden. With a crocked unpleasant scent, its effective for repelling garden pests. Coming in yellow, orange colours, can be implanted in pots or gardens. Being able to be grown anywhere in all solely cold climates. To help conserve moisture in the plants mulch and fertilise to keep them healthy. Regular water and will bloom throughout the summer and autumn and will keep pests away. Garden Guides, 2010 information pegThe largest component of plants is water. 80 to 90% of water is the growing tissue part of the plant, lower water percentage parts are the woody, between 45 and 60% by weight of the water. Transporting minerals acting as a solvent and carbohydrates dissolved. fantabulous solvent due to its unique chemical properties. A reactant in many chemical reactions throughout the plant. group O we breathe everyday is the result of water acting as electron in the reaction of photosynthesis. Maintaining squelch in the plant so the leaves are literally inflated is an important role of water, as limp plants is a lack of water. The water force per unit area is necessary for cellular ph one enlargement, growth and maintenance. John Peterson, 2010 The web movement of atoms or ions of a high concentration to a lower is diffusion. Until a state of equilibrium, diffusion will continue. Temperature, molecule density are the affect in which diffusions rate is, exitring through the stomata into the atmosphere. Through a semi pervious membrane, the diffusion of molecules. Pressure can prevent osmosis. The minimum pressure required for the fluid to be prevented from moving due to osmosis is call osmotic capableness. Until the osmotic potential is balance fluid will enter the cell via it. To help keep the plant cell turgor, any water gained by osmosis is kept. As a result of water entering the cells vacuole developing against the wall is turgor pressure. The water potential is made up by the pressure potential combined with the osmotic potential. Water will move from the cell with higher water potential to the cell with lower water potential if there next to each othe r. Water moves due to the soils higher water potential than the roots and plant parts. The plant will die if there is no net movement in the plants. The loss of water via osmosis is plasmolysis and the shrinkage of protoplasm. If the cell is placed in fresh water this process can be reversed, as the cell is allowed to regain turgor pressure. Permanent damage can come to pass to the cell. Alive or dead tissue, swelling is imbition. It can swell to several times their original volume. Minerals, cellulose and starches in suspension, attraction highly polar molecules is due to this. The initial germination of the seeds is this swelling process. Movement energy of substances is active transit. Enzymes and a pump in the plasma membrane are required for this process. ATP molecules energize the face. Biology online, 2010Transpiration is where 90% of water that enters the plant is loss. Through the leaves is the loss of water vapour, this is transpiration. Loss if water through the cuticle is little than 5%. Not just for the pressure reason, vital to plant life is water and the cellular activities that occur in water molecules presence. The internal plants temperature is regulated by water. From the smallest root all the way up to the smallest leaf is the xylem pathway, internal plumbing system paired with phloem. The plants water needs and resources are maintained in the nutrient transportation system or internal plumbing. Columns of water in the plant form as the water molecules adhere to the xylem and tracheids walls and vessels to cohere each other allowing an overall tension. Water that enters the roots via osmosis, water content from the soil travels up these columns. Enough force to transport water through the plant is the water potentials of the soil and the stomata, from bunghole to top. External input is the minerals in the soil, affects the growth rate and quality. Hydrogen, carbon, nitrogen, potassium, iron, calcium, cobalt, zinc, sulphur, sodium, manga nese, chlorine, oxygen, phosphorus, molybdenum and boron are essential mineral in the plants growth. Minerals vary from plant to plant in which helps them to survive. If the soil is lacking these nutrients and fertilizer isnt used to compensated, the plant will demonstrate mineral deficiencies symptoms. The ratio of nitrogen, potassium and phosphorus compensate the deficiencies. Biology online, 20102.0 HypothesisMicrowave radiation water will affect the plants growth. Boiled water will have minimal impact on the plants growth.3.0 AimTo investigate the effect of microwave and boiled water on plants.4.0 Materials UsedGardening jigaboo4 black P.E.T potsSearles real premium potting mixMicrowave OvenBoiling jug/kettle2 petunia x hybrid2 Calendula officinalisPen and PaperRulerGloves2 measuring jugs5.0 rulePotting PlantsGroup names and plant type experiment were labelled on the pot.Pot was half alter with potting mixed.Plant was removed from seedling tray.Roots of the plant were spread out.Plant was placed into the pot.Pot was then make full with soil surrounding the plant and compacted.Steps 1 to 7 were repeated for each plant.Measuring PlantsPlant height was measured from the base to the highest point and recorded.Number of flowers and buds on the plant were counted and recorded.Stems of the plant were counted and recorded.Heating WaterMeasuring jugs were labelled, boiling water and microwave water.Kettle was filled with tap water and boiled.Glass verification jug was filled with tap water.Jug was placed in microwave for approximately 2 to 5 minutes on high.Water was left to cool.500ml of both boiled and microwave water were measured out.1 of both the boiled and microwave experiment plants was watered.Steps 6 and 7 were repeated for the remaining 2 plants.Each week the method of heating the water measuring were carried out recording the plants development and growth.6.0 railleryThe results of the experiment showed the aims outcome. Two plants Calendula offici nalis and petunia x hybrid were tested for the affect that boiling water or microwaving it had up it. The stimulus was that microwaving water altered the DNA affecting plants. The water travel up the transport system of the plants, known as the xylem like a circulatory system. This is how the water and the dissolved nutrients throughout it is dust throughout the plant. If microwaving water alters its DNA and affects the nutrients which dissolve itself from the soil, the reason it affects the whole plant is due to its transport system. The plants werent modify that oftentimes by the two different waters, although the microwave marigold wilted and died. However there shouldnt be much difference between the boiled and microwave water.The hypothesis was based upon the stimulus of the experiment stating, microwave radiation water will affect the plants growth. Boiled water will have minimal impact on the plants growth. Although the results didnt support the hypothesis, as there wasnt any major difference between the boiled and microwave petunias and marigolds. Although the microwave marigold welted in our experiment other groups may have had boiled plants that welted. The variables would have been the reason as to wherefore we received the results we did. As there was no fertiliser added to the plants and some of them demonstrated the characteristics of lacking nutrients, as fertiliser can assist in this and supply the plant with the nutrients to help its deterioration the plants werent helped. The dying plant couldve have been easily prevented if a substitute nutrient like fertiliser was given to it.Many errors throughout the experiment can be improved. When potting the plants the soil could have been compacted more so there were no air pockets and the water soaked in more. It also wouldve prevented the plants to die. Measuring the data, could have been more accurate by having more than 3 standard measurements, things such as the plants width could have been measured and the plants weight. The standard error ranges which mean the way in which every group maintained their plant was different and play a major affect on them. Such as accidently pouring the wrong water into the incorrect plant would have affected the outcome even though there shouldnt be much of a difference between microwave and boiled water. The environment in which the plants were in also affected them as they were open and exposed to rain and bad weathers. Many things of the experiment could have been improved to get a more accurate result.7.0 certaintyThe hypothesis wasnt supported nor was it wrong as there wasnt a massive difference between the microwave water and boiled water results, it seems that the microwave water plants were growing better than the boiled plants, although only by a minimal amount. The results can lead to further experimentation upon humans and wether microwaving makes us susceptible to cancers and unwholesome diseases. Tests on animals and if over a period of time that microwave radiation can affect you and send packing the body. Does microwave radiation alter foods DNA and prevent our bodies from registering it. The experiment has answered the hypothesis and reached the aim, it has also left many further possible investigations about microwave radiation and its affects.8.0AcknowledgementsI would like to acknowledge the year 10 biology class, Mr. Fesuk the teacher, Ms. Mason student teacher and my group buddies Caitlin, Dorine and Shadae.
