Animal and Plant Cells

Animal cells, including human cells, all contain the same following structures:

Nucleus: Contains the genetice information, controlling the activities of the cell.

Cytoplasm: Where most of the chemical reactions take place.

Cell Membrane: Controls the passage of substances into and out of the cell.

Mitochondria: Where aerobic respiration takes place.

Ribosomes: Where protein synthesis takes place.

In addition to the above features plant cells often have:

Chloroplasts: Containing chlorophyll, they absorb light to produe food via photosynthesis

Permanent Vacuole: Filled with cell sap to provide support for the plant.

Cell Wall: Made of cellulose to strengthen the cell and provide support.
