Holds DNA.

Cell membrane-
Controls all of the cell's communications.

Provides energy for the cell parts by converting sugar into a form of energy.

Cell parts are suspended in the jelly like fluid of the cytoplasm.

Endoplasmic reticulum-
Controls all protein production in the cell.

Golgi Apparatus-
Recieves protenisn from the endplasmic reitculum and packages them for their final destination.

Builds protein

Gives the sell its shape and is in control of the movement of the cell.

Destroys bacteria, viruses and any worn out cell parts.



The nucleaus is a membrane bound strcture. It is the command centre of most cells and is usually most prominent feature within a cell.

Cytoplasm -

Cytoplasm is the substance that fills the cell. It is a jelly-like substance and it is made up of eighty percent water and is usually clear and colourless. Cytoplasm is a thick gel-like substance.

Mitochondria -

They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae.

Ribosomes -

There are two pieces to every ribosome. They are used in the process of protein systhesis. Ribosomes are freely suspended in the cytoplasm or attached to the endoplasmic reticulum forming the rough endoplasmic reticulum.

Endoplasmic reticulum-

The endoplasmic reticulum is a system of membrane-enclosed sacs and tubes in the cell. Their lumens are likely to be all interconnected, and their membranes are continuous with the outer membrane of the nuclear envelope.

Golgi Apparatus-

These consist of a collection of vesiclies and folded membranes. These are usally conected to an endoplasmic reticulum.
