The Eukaryotic Cell

Flagella and CiliaDifferentiate prokaryotic and eukaryotic flagella.

Microtubules Tubulin9 pairs + 2 array

Flagella and CiliaThe Cell Wall and GlycocalyxCell wallPlants, algae, fungiCarbohydratesCellulose, chitin, glucan, mannanGlycocalyxCarbohydrates extending from animal plasma membraneBonded to proteins and lipids in membraneCompare and contrast prokaryotic and eukaryotic cell walls and glycocalyxes.The Plasma MembranePhospholipid bilayerPeripheral proteinsIntegral proteinsTransmembrane proteinsSterolsGlycocalyx carbohydratesCompare and contrast prokaryotic and eukaryotic plasma membranes.The Plasma MembraneSelective permeability allows passage of some moleculesSimple diffusionFacilitative diffusionOsmosisActive transportEndocytosisPhagocytosis: Pseudopods extend and engulf particlesPinocytosis: Membrane folds inward, bringing in fluid and dissolved substances

CytoplasmCompare and contrast prokaryotic and eukaryotic cytoplasms.CytoplasmCytoplasm membrane: Substance inside plasma and outside nucleusCytosol: Fluid portion of cytoplasmCytoskeleton: Microfilaments, intermediate filaments, microtubulesCytoplasmic streaming: Movement of cytoplasm throughout cellsRibosomesProtein synthesis 80SMembrane-bound: Attached to ERFree: In cytoplasm70SIn chloroplasts and mitochondriaCompare the structure and function of eukaryotic and prokaryotic ribosomes.Identify at least one significant difference between eukaryotic and prokaryotic flagella and cilia, cell walls, plasma membranes, and cytoplasm. The antibiotic erythromycin binds with the 50S portion of a ribosome. What effect does this have on a prokaryotic cell? On a eukaryotic cell? OrganellesNucleus: Contains chromosomesER: Transport networkGolgi complex: Membrane formation and secretionLysosome: Digestive enzymesVacuole: Brings food into cells and provides supportDefine organelle.Describe the functions of the nucleus, endoplasmic reticulum, Golgi complex, lysosomes, vacuoles, mitochondria, chloroplasts, peroxisomes, and centrosomes.

OrganellesMitochondrion: Cellular respirationChloroplast: PhotosynthesisPeroxisome: Oxidation of fatty acids; destroys H2O2Centrosome: Consists of protein fibers and centrioles

Peroxisome and CentrosomeCompare the structure of the nucleus of a eukaryote and the nucleoid of a prokaryote.How do rough and smooth ER compare structurally and functionally? The Evolution of EukaryotesDiscuss evidence that supports the endosymbiotic theory of eukaryotic evolution
