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.
Haploid spores give rise to a multicellular haploid leaf-like structure called a thallus. The thallus produces gametes. Green algae are isogamus, meaning they have only one type of gamete, rather than having separate male and female gametes.or this reason, those two groups are sometimes classified as protozoa rather than algae. In this discussion, we will group euglenoids and dinoflagellates with the algae so that we may compare their photosynthetic characteristics. Keep in mind that this inclusion does not imply close relation to other algae.
