Document Summary

Golgi apparatus : modifies and sorts proteins and lipids. Chloroplast : allows plants to harness energy from sun to synthesize sugar. Peroxisomes: break down and synthesizes organic molecules nucleus mitochondria. Nucleus: storehouse for genetic info & and where rna synthesizes. Plasma membrane: regulates passage for molecules in and out of cell ( made up of proteins and phospholipids) Cytoskeleton: provides cell w/ internal structural framework (protein filaments) Vacuoles: contribute to structural rigidity maintains turgor pressure. What happens out of the nucleus ( exported out) Import protein in nucleus ( requires nuclear localization signal) Nucleus has a double membrane structure that allows for movement in and out of the cell. Nuclear envelope defines boundary of nucleus (inner & outer membrane) Nuclear pores allows movement in and out of cell ( required protein transporters found here) Network of interconnected tubules and flattened sacs. Addition of carbohydrates ( glycosylation) of lipids and proteins begin.
