Algae can either be unicellular or multicellular. Seaweeds are examples of multicellular algae. On the other hand, protozoans are unicellular, and they are more animal-like. People describe protozoa as a blob without a definite shape since they lack a cell wall.
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.
