Protists live in almost any environment that contains liquid water. Many protists, such as algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton.ost eukaryotic algae are autotrophic, but the pigments were lost in some groups. Other protists are heterotrophic, and may present phagotrophy, osmotrophy, saprotrophy or parasitism. Some are mixotrophic. Many protists are flagellate, for example, and filter feeding can take place where the flagella find prey.
Thank you... Algae are simple, chlorophyll bearing and photosynthetic non vascular plants whose body is a simple thallus without differentiation into roots, stems and leaves. There are about 35000 species of algae.They include planktons, pond scums, stone worts, sea weeds, sea lettuce etc.Phycology is the branch in botany which deals with the study of algae.Characteristics of Algae. Body is a relatively simple simple unicellular or multicellular thallus, not differentiated into roots, stems and leaves. Unicellular thallus may be non motile, rhizopodial or coccoid.Multicellular thallus may be colonial, palmelloid, dendroid, filametous siphonous and so on. Algae cells exhibit three levels of organization, namely prokaryotic (eg: Myxophyceae), mesokaryotic (eg: Dinophyceae) and eukaryotic (other groups).here are about 35000 species of algae.They include planktons, pond scums, stone worts, sea weeds, sea lettuce etc. Phycology is the branch in botany which deals with the study of algae.
