Photosynthesis

2. a basic structural unit of the thylakoid membrane network of plant chloroplast
3. organelle where photosynthesis occurs
5. gas and plant expels them
10. microscopic holes in the underside of leaves allows oxygen to escape and carbon dioxide to enter
12. membranes inside where the light reactions occur with the electron transport chain
13. dioxide colorless odorless gas
15. color that absorb light produces energy from the sunlight it absorbs
16. the inner membrane of the chloroplast forms a border to the stroma it regulates passage of materials in and out of the chloroplast
18. contains proteins and is therefore permeable to small molecules
19. which open and close stomata
21. a jelly like fluid inside surrounding thylakoids where the Calvin cycle occurs

1. usually refers to xanthophyll and carotene
4. the process of using water carbon dioxide and sunlight to produce glucose
6. the fluid filled internal space of the chlorplast which encircle the grana and the thylakoids
7. a biochemical mechanism in plants by which chlorophyll absorbs light energy for photosynthesis. There are two such mechanisms
8. occurs in the stroma
9. one billionth of a meter used to measure the wavelengths
11. organisms that go through photosynthesis
14. the colors of the light the human eye can see
17. pigments absorb sunlight but do not produce energy directly
20. plants that open their stroma at night
