Animal cells and Plant cells

Animal cells usually have an irregular shape, and plant cells usually have a regular shape. Cells are made up of different parts.

It is easier to describe these parts by using diagrams:

Animal cells and plant cells also contain tiny objects called mitochondria in their cytoplasm

Animal cells and plant cells both contain:

Cell membrane

Cytoplasm

Nucleus

Mitochondria

Plant cells also contain these parts, which are not found in animal cells:

Cell wall

Vacuole

Chloroplasts

The table summaries the functions of these parts:

Part Function Found in Cell membrane Controls the movement of substances into and out of the cell-plant and animal cells Cytoplasm Jelly-like substance, where chemical reactions happen Plant and animal cells Nucleus Carries genetic information and controls what happens inside the cell-plant and animal cells Mitochondria Where most respiration reactions happen Plant and animal cells Vacuole Contains a liquid called cell sap, which keeps the cell firm Plant cells only Cell wall Made of a tough substance called cellulose, which supports the cell-plant cells only.
