CELL ORGANELLE STRUCTURE AND FUNCTION

ORGANELLE
STRUCTURE
FUNCTION

Nucleus double membrane enclosing Directs cell activity

chromatin

Nucleolus spherical body in nucleus partially assemble ribosomes

Ribosomes spherical body in cytoplasm protein synthesis

(also associated w/RER)

Endoplasmic membrane of folded sacs in transport of proteins and other
reticulum cytoplasm SER and RER molecules

Golgi body stack of membranes and sacs in protein packaging factory

cytoplasm

Mitochondria double membrane, outer smooth powerhouse of the cell, site of

inner-cristae folded to increase SA cellular respiration, produces


ATP

Lysosome spherical body in cytoplasm suicide sac contains


digestive enzymes that merge


w/food vacuoles

Microtubules long protein tubes cellular framework

cilia + flagella long protein structures, 9+2 movement of cell

arrangement of microtubules

cell wall cellulose, pectin, lignin framework for support in


plant cells.

cell membrane double proteo-phospholipid layer selective permeability

vacuoles spherical body in cytoplasm contain H2O, digestive enzymes


wastes, food

chloroplast double membrane, spherical body captures sunlight for


photosynthesis

chromoplast spherical body in plant cell synthesize and store pigments

leucoplast spherical body in plant cell store starch, protein, lipid.
