All animals and plants are made of cells.
These cells are the genetic building blocks that makeup tissues and organs in the body of an animal.
The development of these genetic materials is controlled by the cells.
Animal cells are made up of distinct parts
The cell membrane is a selectively permeable membrane that controls the entry and exit of materials. It separates the cytoplasm from the surrounding environment.
The cytoplasm contains the living material within a cell, not including the nucleus.
The nucleus is the 'brain' of a cell. It contains the cell's chromosomes DNA and controls what happens inside it.
The mitochondria are structures within the cytoplasm that control aerobic respiration. This is the process of breaking down nutrients into energy.
