CELL

​Cells are the smallest unit of life and the building blocks for all organisms

​Animal cell

The four key components of most animal cells are:

• Nucleus - this contains the genetic material (DNA) of the organism and controls the cell’s activities.

• Cytoplasm - the liquid that makes up most of the cell in which chemical reactions happen. This is mainly water.

• Cell membrane - a flexible outer layer that surrounds the cell and controls which substances can pass into and out from it.

• Mitochondria - tiny parts of cells floating in the cytoplasm where energy is released from glucose from food. The mitochondria, found in the cell cytoplasm, are where most respiration happens.
