1. What does the Leaf cell do?
- The leaf cell absorbs light energy for photosynthesis. Packed with chloroplasts. Regular shaped, closely packed cells form a continuous layer for efficient absorption of sunlight.
- The leaf cell absorbs water and mineral ions from the soil. Long 'finger-like' process with very thin wall, which gives a large surface area.
- The leaf cell contains a thin outer membrane to let oxygen diffuse through easily. Shape increases the surface area to allow more oxygen to be absorbed efficiently. No nucleus, so the whole cell is full of haemoglobin.

2. What is diffusion?
- Dissolved substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen.
- Diffusion is a mixture of two proteins present in cereal grains, especially wheat, which is responsible for the elastic texture of dough.
- an amino acid containing sulphur and important in the metabolism of fats.
3. The the animal got chloroplast?
4. What's the function of the cytoplasm?
- Most chemical processes take place here, controlled by enzymes
- Contain chlorophyll, which absorbs light energy for photosynthesis
5. What function does the Nucleus do?
- The nucleus is where the protein synthesis.
- The nucleus contains genetic material, which controls the activities of the cell.
- The nucleus stores the food and any variety of nutrients and cell might need to survive. It is filled with sap to help the cell turgid.
- The nucleus release most of the energy by respiration here.
