organelles & their functions

nucleus

genetic material for the cell

Golgi apparatus

packages proteins into membrane-bound vesicles for excretion from cell, further modifies proteins + labels it so its ready to leave cell

smooth er

no ribosomes, makes lipids, stores calcium, detoxifying cells

nucleolus

inner part of nucleus that begins assembly of ribosomes

plasma membrane

contains + surrounds cell, controls what comes in + out of cell

rough er

modifying proteins, has ribosomes

mitochondria

makes ATP

nuclear envelope

double-membrane structure, separating nucleus from cytoplasm in eukaryotic cells

ribosomes

makes proteins

chromatin

within nucleus, packages dna proteins into complex structures

peroxisome

breaks down fatty acids + amino acids to hydrogen peroxide then into hydrogen + water

lysosome

digestive enzymes that break down old worn out cell parts

cilia

hair-like structures on surface of cells perform movement and sensory functions

cytoskeleton

network of protein fibers, microtubules, found in cytoplasm of eukaryotic cells, structure/pathways

vesicle

transport from one part of cell to another, digesting, or storing materials

microtubules

cytoskeletal element, thick, straw-like structure, made up of tubulin, moves bigger materials such as vesicles
