Plant Sciences, Zoology & Evolution / Re: Why aren't algae and fungi in the plant kingdom?

Hi, this is something that confused me aswell.
In short, fungi cannot photosynthesise. they live off remains.
Algae can photosynthesise. However, many algae are unicellular, and cannot be classified as "plants". Those that are multicellular don't have defining characteristics - roots, stems, leaves, xylem etc...  they are also adapted solely for water. E.g they don't have waxy cuticle to prevent water loss. Plus, scientists prefer to group - if one algae doesn't fit plantae, then none of them do. Plants are therefore classified as Protista. Protista is, i find, one of those taxonomical groups that contain all the life forms that don't fit anywhere else. Slime mounds and Protozoa are in Protista. Some scientists feel that green algae, and all other multicellular algae, belong in plantae. Some scientists believe that all algae belong in an extra kingdom-chromista. It's all a matter of opinion I'm afraid. Hope this helps a bit.
