- Cells
- Animal Cells
- Nucleus
- Contains Genetic Material that controls activities of the cell.
- Cytoplasm
- Gel-Like substance where most chemical reactions happen. Contains enzymes that control these reactions.
- Cell Membrane
- Hold the cell together and controls what goes in and out.
- Mitochondria
- Reactions for Respiration take place. Respiration releases energy that the cell needs to work.
- Ribosomes
- Where Proteins and made.
- Nucleus
- Plant Cells

- Cytoplasm
- Cell Membrane
- Mitochondria
- Ribomes
- Rigid Cell Wall
- Made of cellulose. Supports cell and strengthens it.
- Permanent Vacuole
- Contains Cell Sap, a weak solution of sugar and salts.
- Chloroplasts
- Where Photosynthes occurs, which makes food for the plant. These contain Chlorophyll.
- Single Celled Organisms
- Yeast
- Bacterial Cells
- No Nucleas
- Diffusion (Cell Membrane)
- Diffusion is the spreading of particles from an area of High Concentration to and area of Low Concentration
- Small Molecules like Oxygen and Amino Acids diffuse through Cell Membranes.
- Diffusion is the spreading of particles from an area of High Concentration to and area of Low Concentration
- Specialised Cells
- Palisade Cells
- Adapted for Photosythesis because they are packed with Chloroplasts, Tall Shape means lots of Surface Area and Thin so easy to pack together.
- Guard Cells
- Opens and closes the Stomata. When the pant has lots of water it swells therefore the stomata opens so gases can be exchanged for Photosythsis.
- Red Blood Cells
- Concave shape makes Surface Area larger. Packed with Haemoglobin.
- Palisade Cells
- Cell Organisation
- Similar Cells are organised into Tissues (Group of Similar Cells). For Example, Glandular Tissue, secretes hormones.
- Tissues are organised into Organs. For Example, Muscular Tissue which contracts to churn up food.
- Orangs group up to form Organ Systems. For Example, Digestive System. The Small Intestine absorbs small soluble food molecules.
