BIOL 371 Lecture Notes - Lecture 1: Ctenophora, Opisthokont, Nucleoid
Document Summary
Eukaryotes: cytoskeleton, not all cells have all of the following, structural elements in the cell (gives shape and movement to the cell, microtubules- hollow tube formed from tubulin dimers, microfilaments- double helix of actin monomers for: Chloroplast organelle: sexual reproduction, provides diversity through gametes and fusion of gametes, some can use this but all are capable, vertical transmission in eukaryotes (1n+1n=2n) haploid to. Cilia and flagella: allow movement of the cell, 9+2 arrangement of microtubules. The rise of multicellularity: who is a(cid:374)d (cid:449)ho is(cid:374)"t, cyanobacteria, the great oxygenation event which produced oxygen into the atmosphere after all the iron in the ea(cid:396)th"s (cid:272)o(cid:396)e had (cid:396)usted. De(cid:448)eloped the a(cid:271)ility to use oxidative phosphorylation: mitochondria and aerobic respiration, then multicellularity. Photosynthesis in eukaryotes: photosynthetic organisms, theorize photosynthesis was acquired independently by many different organisms, multi and single cellular, acquired 460 million years ago in land plants.
