Controls what enters and leaves the cell. E.g. Oxygen, Carbon Dioxide, glucose
1 of 15
Nucleus
A large structure that contains DNA.
2 of 15
DNA
Instructions for the building and working of the cell.
3 of 15
Cytoplasm
Jelly-like substance that fills the cell - many reactions take place here.
4 of 15
Mitochondria
Tiny structures where respiration takes place, releasing energy for cell processes.
5 of 15
Chloroplast
Structures where photosynthesis takes place to make food for the plant cell.
6 of 15
Cell Wall
Made of Cellulose, and its tough so that it helps support the cell and helps it keep its shape.
7 of 15
Large central vacuole
Contains cell sap, which helps to keep the plant cell rigid.
8 of 15
Flagellum
Helps a bacteria cell to move.
9 of 15
Chromosomal DNA
A single loop of this lies free in the cytoplasm. This carries most of the bacterial genes.
10 of 15
Plasmid DNA
Some bacteria have extra circles of DNA called plasmid DNA. Plasmids contain additional genes that are not found in chromosomes.It is separate from the main genetic information.

Light Microscope
Uses light to magnify objects. The greatest possible magnification using a light microscope is about x2000.
12 of 15
Electron Microscope
Uses electrons to view an object. This makes it possible to magnify objects up to about x10 millions. We can see far more detail in cells with an electron microscope than a light microscope.

Magnification of an Object
Magnification of object = magnification of eyepiece x magnification of objective
14 of 15
Actual size
Actual size = image size/ magnification
