Cells

Cell wall- made up of tiny fibres and supports the cell
Cell membrane- this is the barrier around the cell. It controls what goes in and out.
Cytoplasm- where the chemical reactions take place.
Mitochondria- this is where respiration happens and where the energy is transferred.
Ribosomes- protein is made here and turned into amino acids
Nucleus- this is the brain of the cell and controls it.

Specialised cells

Red blood cell- lacks a nucleus and has a large surface area. It's function is to bind the haemoglobin with the oxygen and to transport it around the body.
Phloem- Found in the roots, stems and leaves. It's function allows sugar or nutrients to move throught the plant.
Nerve- short extensions at end and one long nerve. Recieves pulses from other cells and impulses then travel along the nerve, which prevents the loss of impulse.
Xylem- Found in the roots, stems and leaves with a hardened cell wall, which is hollow inside. Transports water round the plant
Muscle- Cell is long, thin and full of protein. The function of it is to contract and this brings about movement.
Sperm- cell has a head containing a nucleus and a long tail. The tails function helps it to swim to the egg.
Ciliated epithial- tall column shaped cells. the function is to move the bacteria out of the windpipe.
Palisade mesophyll- found in the upper part of the leaf column. The function is to use the many chlorophyll that it is packed with to help absorb the light for photosynthesis.
Plant root hair- found in young root and helps to absorb water.
