- Cells tissue and organ
- cell tissue and organisms
- Animal and plant cells
- Nucleus controls cell activity
- Mitocondria where energy is released
- Cell membrane controls the movement of substances which enter an leave the cell
- Cytoplasm is a jelly like substance that chemical reactions take place
- Animal and plant cells
- Tissues and organs
- Muscle and tissues contract this brings about movement
- Glandular tissues - produces substances such as enzymes and hormones
- Epithelial tissue's cover most of the body
- in plants there is xylem and phloem which transport minerals
- Specialised cells
- As a organism matures each cell becomes specialised
- If a cell has many mitochondria it will need lots of energy i.e. Sperm cell
- Specialised cells
- As a organism matures each cell becomes specialised
- If a cell has many mitochondria it will need lots of energy i.e. Sperm cell
- Neurones are specially adapted to carry signals from receptors to the CNS
- If a cell has a lot of ribosomes it produces many protein glands cells

- Diffusion
- The movement of particles along a concentration gradient of higher to lower
- Examples: Diffusion of Oxygen into cells of the body through bloodstream as the cells are respiring
- The difference between the 2 gradients is called a concentration gradient
- Bacteria an yeast
- Bacteria cells have a cell wall and cell membrane which surrounds the cytoplasm
- bacteria does not have a nucleus so the genetic material is in the cytoplasm
- Bacteria are very small and can only be seen with a microscope
- Yeast is a single celled organism with a nucleus cytoplasm membrane and a cell wall
