Plant Biology

3. The female reproductive part of a flower.
4. The waxy, waterproof layer that covers the leaves and stems of most plants.
7. The secretion of droplets of water from the pores of plants (not to be confused with dew).
9. The inner tissue of a leaf, containing many chloroplasts.
10. The pressure of water pushing the plasma membrane against the cell wall, keeping the plant upright.
12. The evaporation of water from plant leaves.
14. Nutrient-rich tissue that provides nourishment to the developing embryonic plant.
16. Pairs of cells that surround stomata and control their opening and closing.
17. The male reproductive part of a flower, consisting of the anther and filament.
18. Vascular tissue that carries water upward from the roots.

1. A plant's growth response to touch (like vines climbing a fence).
2. A growth response to gravity (roots growing down, stems growing up). 10.
3. Vascular tissue that transports sugars from the leaves to the rest of the plant.
5. A plant hormone that promotes cell division (cytokinesis).
6. The organelle where photosynthesis takes place.
8. An organism that can produce its own food using light, water, or chemicals.
9. Regions of unspecialized cells where plant growth occurs through rapid cell division.
11. Microscopic pores on the leaf surface used for gas exchange.
13. A hormone that promotes cell elongation and is responsible for phototropism.
15. A gaseous plant hormone that simulates fruit ripening.
