Document Summary
Lomoar cpsd| 987298: compartment inside thylakoid sacs is called thylakoid space. Thylakoids are sometimes stacked like poker chips, each stack = a granum. Grana = chloroplast"s solar power packs, site where green chlorophyll molecules that are embedded in thylakoid membrane, trap solar energy . Review: eukaryotic cell structures can be grouped on the basis of four main functions. Theme: structure is correlated with function : genetic control . Ribosomes produce the protein coded for in instructions: manufacturing, distribution, and breakdown . Rough er synthesis of membrane lipids & proteins, secretory proteins, & hydrolytic enzymes. Formation of transport vesicles : smooth er lipid synthesis, detoxification in liver cells, calcium ion storage. Golgi apparatus modification & sorting of macromolecules, formation of lysosomes and transport vesicles. Lysosomes (in animal cells & some protists) digestion of ingested food, bacteria, and a cell"s damaged organelles & macromolecules for recycling. Storage of chemicals and cell enlargement (central vacuole)
