Document Summary
Red algae and green algae (land plants) archaeplastids. Microfilament-a double helix of actin (protein) monomers long spiraling and important in skeletal muscle. Intermediate filaments-strong fibre composed of intermediate filament proteins support and structure. *cytoskeleton (internal scaffolding giving shape /structure to cell) *endomembrane system (series of inside cell membranes, internalized membrane bound structures) *primary genome of multiple, linear chromosomes (linear segment dna, controls genome expression, selectively turn [on]) * 80s ribosomes turn rna signal on (60 & 40s subunit) *plastids (in algae and plants) cyanobacteria blue green algae endosymbiont. *sexual reproduction (provides diversity through gametes and fusion of gametes. Evidence for endosymbiotic origins circular dna (chloroplast dna looks like cyano dna), independent fission, size, double membrane, certain proteins specific to bacterial cell membrane are also in mito and chloro membranes, 70s ribosomes, prokaryote dna in eukaryote genome. 9+2 arrangement of microtubules (9 out and 2 in pairs).
