-They also don't have differentiated cells. -different reproduce features -no vascular tissue
Select reasons why members of phyla Acrasiomycota, Myxomycota, and Oomycota not classified in the kingdom Fungi.
-When present, the cell walls are composed of cellulose. -At some point in their life cycle, these species are motile.
In the past, euglena have been classified as a protozoan because they have:
