Separates the interior (inside) of the cell from the environment outside. It is also selectively permeable.
Selectively Permeable
It has control over which substances enter and exit the cell
Nucleus
Contains chromosomes ( which contains the cell’s genetic material)
Ribosomes
Ribosomes are responsible for synthesising proteins
Mitochondria
Where aerobic respiration takes place
Cytoplasm
A jelly-like fluid that fills the cell. Where most of the cells chemical reactions take place.
Mitochondria are responsible for providing energy for the cell
Cell membrane controls what enters or leaves the cell
Most animal cells differentiate early on in their development. In mature animals, cells mostly divide to replace cells and repair tissues that are already present. New tissues are rarely created by cell differentiation.
