TRANSPIRATION

1. What do guard cells do when cells in a leaf begin to dehydrate?

1. What do guard cells do when cells in a leaf begin to dehydrate? They flatten out and close the stomate

A. xylem

xylem Tube which carries water from the roots to every cell in the plant.

Phloem

Phloem Tube which carries glucose(sugar) created during photosynthesis from the leaves to the rest of the plant.

Stomates

Stomates An opening found on the bottom of leaves to let gases in and out of a plant.

Guard Cells

Guard Cells Two cells found around stomates that control the size of the openings on leaves.

Transpiration

Transpiration The movement of water through a plant from roots through the stem and out of the leaves

Buttress

Buttress an external prop or support (root) to steady a plant

3. What controls the size of the opening on leaves?

3. What controls the size of the opening on leaves? The GUARD CELLS control the opening on leaves (STOMATES)

4. What part of the plant is responsible for gas exchange?

4. What part of the plant is responsible for gas exchange? The STOMATES are responsible for gas exchange on plants

5. How does the PALOVERDE perform photosynthesis without leaves?

5. How does the PALOVERDE perform photosynthesis without leaves? The entire tree is green and performs photosynthesis.

6. What are the openings on leaves that let gases in and out called?

6. What are the openings on leaves that let gases in and out called? STOMATES

7. Why do the leaves on a plant begin to wilt?

7. Why do the leaves on a plant begin to wilt? Wilting is an adaptation for plants to prevent losing too much water.

8. Where are most of a plants stomates found and why?

8. Where are most of a plants stomates found and why? Stomates are found on the bottom of the leaf to keep them out of direct sunlight.

9. What does it mean when a plant is germinated?

9. What does it mean when a plant is germinated? Germinated means the start of growth in a plant.

10. Why is transpiration necessary for a plant to survive?

10. Why is transpiration necessary for a plant to survive? Transpiration delivers water to each cell in a plant.

11. Describe the process of transpiration from water entering a plant to leaving the plant.

11. Describe the process of transpiration from water entering a plant to leaving the plant. Enters the ROOTS Up through the XYLEM to each cell in the plant Out through the STOMATES

12. If you place a plastic bag over the leaves of a plant during a drought, would you expect to see a lot of water condensing in the bag or just a little? Explain why.

12. If you place a plastic bag over the leaves of a plant during a drought, would you expect to see a lot of water condensing in the bag or just a little? Explain why. Just a little the plant wants to conserve the water that it has. Water is scarce during a drought so you would see very little water in the bag

13. Describe GERMINATION

13. Describe GERMINATION Plant Water Seed coat softens Seed swells and splits Roots grow down Shoots grow up Leaves form flowers

14. In which order do the parts of the plant appear?

14. In which order do the parts of the plant appear? ROOTS SHOOTS LEAVES FLOWERS
