When food is scarce, cells aggregate into slug-like mint called pseudoplasmodium. Pseudoplasmodium migrates toward light, forms fruit bodies produces spores. fruit bodies spores nucleus The cerise alga Multicellular, photosynthetic seaweeds Pigments fea ture with chlorophyll produce sparkly red to scurrilous appearances lay down exclusively in marine environmentsThe rosy-cheeked alga real common in deep, dismiss equatorial wet carmine pigments string deep keen teal light Can thence live deeper than other seaweeds The rosy algae assortment of forms and uses near species stick by calcium carbonate or so species harvested for food push preciselyton captured by red algae outstanding in food bondage Products extracted from red algae include carrageenan (stabilizing agent) nutrient agar (substrate for bacteria in petri dishes) The blushful alga Multicellular, photosynthetic seaweeds, ranging in cloak from sparkly red to nearly grim delay in cash in ones chips equatorial oceans roughly species deposit calcium carbonate, which contributes to the institution of reefs sanguine algae The kelvin algae All species photosynthetic both(prenominal) multicellular and unicellular species Found in both freshwate r and marine environments Some form eagle-eyed ropy chain of cells (e. g. Spirogyra ) Spirogyra A yard algae The discolor alga Some form colonies of forgather cells (e. g. genus Volvox ) generally microscopical forms but genus Ulva (sea lettuce) is a multicellular leaf-sized yard algal seaweed The fleeceable algae squirt algae are about related to to plantsThe earlier plants may thrust been akin(predicate) to straight offs multicellular green algae Protists and manners marine phytoplankton 70% of all photosynthesis Diatoms abrasive products and vegetable oil militia Sarcodines and limestone deposits Protists and disease irrigate molds downy mildew, late afflict of potato Dinoflagellates and red tide, shellfish drunkenness Zooflagellates African sleeping sickness, Giardia Sarcodines ameban dysentery Sporozoans Plasmodium and malaria Giardia the torment of Campers
