Resource summary
Cells
Specialised Cells
Sperm
Whip like tail to propel, Streamlined body, release dissolving enzymes to break egg, contain many mitochondria so they have energy to swim.
Red Blood Cell
Large surface area so it can carry more oxygen, thin membrane allows oxygen to pass in + out easily
Leaf cell
Packed with chloroplasts. Regular shaped, closely packed cells form a continuous layer for efficient absorption of sunlight
Animal Cell
Nucleus
It contains the DNA of the cell, and controls it's growth and reproduction.
Cytoplasm
Maintains shape and consistency of the cell. All the chemical reactions take place in this area.
Cell membrane
Encloses the cytoplasm of the cell, regulates the passage of substances in/out of the cell. This process happens using diffusion. It's semi-permeable.
Plant cells
Nucleus
Vacuole
Removes unwanted substances from the cell. Keeps in turgid.
Cytoplasm
Chloroplasts
Food making structure (green colour because they contain chlorophyll) which absorb the sun's energy and convert it to chemical energy (photosynthesis)
Cell wall
Protection, and shapes the cell. Made up of cellulose.
Cell membrane
Mitochondria
Known as 'the power house' of the cell. It acts like a digestive system, breaking down food for energy etc
