Plant Nutrition

4. Transports sucrose and amino acids produced from the leaves to other parts of the plant.
5. anchors the plant firmly in the ground, absorbs water and minerals from the soil
7. a gas made of two oxygen and one carbon atom - a limiting factor in photosynthesis
10. An outer layer of cells that form a transparent protective layer (against fungi and bacteria). *Chloroplasts are absent.
14. adapted to make food for the plant by carrying out photosynthesis
15. the organelle in some plant cells which are the site of photosynthesis - contain chlorophyll
16. the vascular bundle in a leaf
18. Cells are rectangular and stand on their end. They contain a large number of chloroplasts.

1. excess glucose is stored in leaves in the form of this polymer
2. Pores are present on the lower epidermis. Allows diffusion of gases in and out of the leaf including water vapour.
3. Pair of bean-shaped cells that open or close the stoma. Contain chloroplasts.
4. the fundamental process by which plants manufacture carbohydrates from raw materials using energy from light
6. a mineral required for making chlorophyll (and so essential for photosynthesis) found in the soil as ions
8. the most important plant mineral used for making leaves found as soluble nitrate ions
9. Waxy substance secreted by upper epidermal cells to reduce water evaporation from leaf surface.
11. Transports water and mineral ions from roots to leaves.
12. a green chemical found in some plant cells (especially palisade cells) which is able to capture light energy
13. the loss of water from leaves through the stomata
17. the tissue between the xylem and phloem in a vascular bundle
