Plants I

1. outer layer of the stem/root
5. transparent upper layer of cells in a leaf containing no chloroplasts
8. bundles areas where phloem and xylem are bundled together
11. layer in a leaf that contains air spaces to allow easy diffusion of gases
16. layer of cells that contain stomata
19. one of the most important minerals for plant growth; needed for chlorophyll to work
20. transports water and minerals to the leaf from the roots; made of dead cells
21. one of the most important minerals for plant growth; needed to make proteins, chlorophyll and DNA
22. controls the opening and closing of the stomata
23. the carbohydrate that plants use to make cell walls
24. layer of lipid that prevents water loss from leaf
25. indicator solution which changes in colour in response to changes in carbon dioxide concentration; yellow – high CO2 levels, orange – atmospheric CO2, purple – low CO2 levels
26. the loss of water vapour from the leaves of plants; rate affected by light intensity, temperature, humidity & wind
27. the carbohydrate molecule that plants use to store glucose/energy

2. main site of photosynthesis in a leaf; cells contain lots of chloroplasts
3. transports sucrose and amino acids from the leaf
4. carbon dioxide + water → glucose + oxygen; requires light and chlorophyll
6. one of the most important minerals for plant growth; need to make DNA and cell membranes
7. allow easy diffusion of gases through the leaf
9. the organelle where photosynthesis occurs; contains chlorophyll
10. specialised pore in a leaf to allow gases to move in and out of leaf
12. one of the most important minerals for plant growth; needed for enzymes to work
13. of the stem/root that produces new plant cells
14. factor the component of a reaction which is it shortest supply so prevents the rate increasing
15. passage of water and minerals through the roots, stem and leaves of a plant
17. main organ of a plant for photosynthesis
18. the movement of oxygen and carbon dioxide in and out of the leaf
