Cytoplasm- A liquid where chemicals changes happen.
Nucleus- Packets of green colour which help the plant make food.
Cell membrane- This surrounds the cell. It lets things move in and out of the cell.
Cell wall- This controls everything that happens inside the cell.

Different types of cell
Red Blood cell- Carys oxygen around the body. They do not have a nucleus. This gives them more
room to carry more oxygen .
Sperm cell- Produce by a male animal joins with the egg from the first cell of a new baby. To help it
swim a long way, it has a long tail.
Egg cell- They are large so they can store a lot of food. Once the egg and sperm have joined
together, the new baby needs the food to help it develop properly.
Nerve cells-Carry message around your body. Nerve cells are long so they can carry messages a

and plants.
Organs- Tissue putting together makes an organ which makes an organ system. Organ 1, organ 2,
organ 3 and organ 4arre connected together. They are important to our body to make us live.
Sensory system- Eyes, ears and nose.
Reproductive system- Ovaries and testers.
Blood system- Heart and blood vessels.
Excretory- Kidney And liver
Breathing system- Wind wipe
