Organelles

nucleus

nucleus

contains genetic information for the cell

ribosomes

small complex proteins that assemble proteins from mRNA

golgi apparatus

packages proteins into membrane-bound vesicles for excretion from the cell

endoplasmic reticulum

synthesizes cellular materials. subdivided into SER and RER

nucleolus

substructure of the nucleus that synthesizes ribosomal DNA

mitochondria

powerhouse of the cell that preforms cellular respiration

vacuoles

empty “bags” within the cell

vesicles

packages of cell membrane that contain material for transport into or out of the cell

cytoskeleton

a scaffolding of tubes providing internal support for the cell

flagells/cillia/pili

protein filaments that allow cells to move

cell wall

cellulose structure supporting the cell

chloroplasts

photosynthesizing organelles

central vacuole

water filled sac in the middle of plant cells

lysosomes

structure containing enzymes that break down unwanted materials

centrosomes

organelles containing centrioles
