Cell Organelles and Their Functions in Eukaryotic Cells

Nucleus

Contains genetic material 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 (permanent, stationary organelle)

Endoplasmic Reticulum

Synthesizes cellular materials. Subdivided into SER and RER

Nucleolus

Substructure of nucleus that synthesizes ribosomal RNA

Mitochondria

Powerhouse of the cell that performs cellular respiration

Vacuoles

Empty 'bags' within the cell

Vesicles

Packages of cell membrane that contain materials for transport into or out of the cell

Cytoskeleton

A scaffolding of tubes providing internal support for the cell

Flagella/Cilia/Pili

Protein filaments that allow cells to move

Cell Wall

Cellulose structure supporting the cell

Chloroplasts

Photosynthesizing organelles

Central Vacuole

Large water-filled sac in the middle of plant cells

Lysosomes

Structures containing enzymes that break down unwanted materials

Centrosomes

Organelle containing centrioles
