Document Summary

Protists small eukaryotes that are not plants, animals or fungi. Cytoskeleton provides structural support and allows eukaryotes to have irregular shapes. Structural and functional diversity of protists: most used organelles in protists nucleus, endoplasmic reticulum, golgi apparatus and lysosomes, diverse in nutrition, mixotrophs combine photosynthesis and heterotroph nutrition, reproduction also varies. 4 supergroups of eukaryotes: excavata (cid:862)e(cid:454)(cid:272)a(cid:448)ated groo(cid:448)e(cid:863) o(cid:374) o(cid:374)e side of (cid:272)ell (cid:271)od(cid:455, sar clade. Include some of the most important photosynthetic organisms: archaeplastida. Key photosynthetic species that form the base of the food web in some aquatic communities: unikonta. Non-amoeba protists related to animals or fungi. Plastid evolution: a closer look: mitochondria descended from bacteria that was engulfed by cell with archaeal lineage, heterotrophic eukaryotes engulfed cyanobacterium, which then evolved into plastids. Cyanobacteria are gram-negative, which means they have two cell membranes (cid:894)i(cid:374)(cid:374)er plas(cid:373)a (cid:373)e(cid:373)(cid:271)ra(cid:374)e a(cid:374)d outer (cid:373)e(cid:373)(cid:271)ra(cid:374)e that"s part of the (cid:272)ell (cid:449)all(cid:895) Red and green algae both have two membranes.
