Cell Organelles and Their Functions

The Animal Cell

The Plant Cell

The Cell Membrane Function- controls the movement of materials into and out of the cell

The cytoplasm Cytoplasm fills cell from the nucleus to the cell membrane; includes fluid, cytoskeleton, and all organelles (except nucleus)

The endoplasmic reticulum A pathway for the transport of materials throughout the cell; rough and smooth

The nucleus Holds genetic material; controls cell functions

Nucleolus Round body within the nucleus; where ribosomes are made.

Ribosomes They build protein; made of RNA and protein. Some are free, some attached to ER.

Lysosomes Contain digestive enzymes that break down large molecules, old cells, worn-out organelles

Mitochondria The powerhouse of the cell; transfers energy from organic molecules to ATP

Golgi Apparatus Packages and secretes products of the cell.

Centrioles (animal cells) Involved in cell division in animal cells

Vacuoles Store food, waste, and water and dissolved materials. Animal cell vacuoles form and reform over and over again.

Cell Wall Gives a plant cell its shape; provides structure; not found in animal cells

Cilia Short hairlike structures that enable a single-celled organism to move; also line respiratory tract

Flagella Long, hairlike structures used for movement

Chloroplast Contains chlorophyll to capture light for photosynthesis; site of photosynthesis

Chromosomes Rod-shaped bodies found in the nucleus; composed of DNA

Microtubule Cylinders that support and give the cell shape
