HW:
Daily Review of class notes.
Test corrections due Monday
Do Now:
State the relationship between light intensity and amount of photosynthesis?
State the relationship between carbon dioxide concentration and amount of photosynthesis?
Draw a graph that represents both relationships.
Why do prolonged high temperatures decrease photosynthesis?

2. Aim: How are plants adapted to perform photosynthesis?

3. How are we adapted for heterotrophic nutrition?

4. 1) Where does photosynthesis happen?

5. Where in the leaf does photosynthesis happen?
Cuticle
Keeps moisture
Palisade
Photosynthetic cells
Absorb light
Spongy layer
Photosynthetic cells
Allow gas passage

6. 2) How are materials transported?

7. How do H2O and nutrients get into the plant?

8. TRANSPORTS WATER TO LEAF
Xylem
TRANSPORTS WATER TO LEAF
Transpiration- evaporation of
water from leaves

9. 3) What path does water takes through a plant?
Into roots
Through xylem
To leaves
Out through stomates when guard cells are open

10. 4) What is transpiration?
Evaporation of water off of leaves

11. TRANSPORTS NUTRIENTS FROM…
Phloem
TRANSPORTS NUTRIENTS FROM…
The leaf to the roots.

12. 5) How does CO2 get inside the leaf?
GUARD CELLS OPEN STOMATES

13. Should the stomates always be open?
WATER
VAPOR

14. 6) What happens if they are always open?
Too much water will exit and the plant will wilt.
