What are the 2 different types of Microscopes
Light Microscope
Electron Microscope
Differences in Light Microscope and Electron Microscope
Light Microscopes have less magnification but can see colour
Electron Microscopes have more magnification but can only see black and white

Mitochondria
Structure and Use of Cytoplasm
-Gel like substance composed of water and dissolved solutes
-Supports and protects internal structures
-Site of chemical reactions
Structure and Use of Nucleus
-Contains DNA which controls the activity of the Cell
Structure and Use of Ribosomes
-The site of protein synthesis
Structure and Use of Mitochondria
-The site of aerobic respiration
Structure and Use of Cell Membrane
-Holds the cell together
-separates the inside of the cell from the outside
-Controls what substances Enter or Leave the cell
Structure and Use of Cell Wall
-Made of cellulose(polymer of glucose)
-Gives the cell extra support and holds its shape
-Provides protection
Structure and Use of Chloroplasts
-Contain green Chlorophyll pigment which absorbs sunlight to be used in Photosynthesis
Structure and Use of the Permanent Vacuole
-Contains Cell Sap (solution of sugars and salts)
-Used for the storage of certain minerals
-Helps support the cell’s shape
What are the 6 levels of Organisation
Organelles - Cell - Tissue - Organ - Organ System - Organism
