Cell Structure

The plasma membrane is a permeable membrane around the cell which controls any exchange in and out of the cell.
The fluid mosaic model, suggested by Singer and Nicholson, said that the plasma membrane has a phospholipid bilayer, two layers with the hydrophobic tails together and the hydrophilic heads apart.
It contains glycolipids, glycoproteins, transmembrane proteins and surface proteins.
This membrane also acts as a barrier against certain objects or substances.

The largest organelle within the cell.
It's enclosed by two membranes in an envelope.
The Nucleus contains chromatin, which is the extended form taken by chromosomes during interphase, as well as a nucleolus.

A system of flattened membranes called cisternae (mainpoint: I spelt it wrong in the diagram, sorry).
It's a continuous single membrane which is also the nuclear outer-membrane.
When ribosome's are found on its surface its known as a rough ER and it transports any proteins made by the ribosome's.

Similar in structure to the endoplasmic reticulum (ER) but is more compact and is made up of flattened sacks.
It's functions include transporting and storing lipids, producing glycoprotein, forming lysosomes and producing secretary enzyme.

This contains digestive enzymes from the remainder of the cell and one of its purposes is destroy old organelles.

Chloroplasts are large organelles, usually in a biconvex shape, and about 4-10μm long and 2-3μm wide.
Within plants most chloroplasts are found in the mesophyll cells of leaves.
The stages of photosynthesis take place within the chloroplast, stage 1 within the granum and stage 2 within the stroma.
