Document Summary

Algae: 15 algal phyla recognized, distinguished based on combination of, physical & molecular characteristics: Cellular organization: common algal phyla, cyanophyta (blue green algae, rhodophyta (red algae, eugleophyta (euglenphyta) Botany lecture 1: chlorophyta (green algae, pyrrophyta (dinoflagellates) Algae: the protist groups are photosynthetic algae, green algae are particularly significant, extant vascular plants are derived from a green algae ancestor, heterotopic protists. Algae: evolutionary importance: life first began on earth approx. Algae: evolutionary importance: algae thrive in terrestrial environments. Inconspicuous: common terrestrial environments algae can be found include, tropical rainforests, snow, mud, sand, rocks, buildings, animals. Turtles, snails, rotifers, worms, crustaceans, alligators, 3-toed sloths: this three-toed sloth is covered in algae. Its fur provides a (cid:862)(cid:373)i(cid:374)i ecosyste(cid:373)(cid:863) for moth species and many micro- orga(cid:374)is(cid:373)s. lucky it"s so slow: recent molecular studies have re-evaluated the evolution of green algae (phylum. Chlorophyta: based on vegetative, morphological, ultrastructural characteristics (cellular characteristics)
