Question

1. the second stage of photosynthesis is called the:
2. the gas given off by an organism (such as ourselves) after cellular respiration is called...
3. molecules that absorb certain wavelengths of light and reflect or transmit others?
4. gel - like material that surrounds thylakoid.
5. stacks of disc - shaped structures that contain chlorophyll are called:
6. process by which autotrophs convert sunlight to a usable form of energy.
7. how many phosphates does atp have?
8. plants store extra energy as:
9. the colors we see are the colors being reflected by pigments. true or false
10. how many phosphates are in adp?
11. what is a heterotroph?
12. what color of wavelength do plants reflect and not absorb?

Explanation:

1. The second stage of photosynthesis is the Calvin cycle, which uses ATP and NADPH from the first - stage (light - dependent reactions) to fix carbon dioxide into sugars.
2. Organisms release carbon dioxide as a by - product of cellular respiration.
3. Pigments are molecules that absorb certain wavelengths of light and reflect or transmit others.
4. The stroma is the gel - like material that surrounds the thylakoid.
5. Grana are stacks of disc - shaped thylakoids that contain chlorophyll.
6. Photosynthesis is the process by which autotrophs convert sunlight into a usable form of energy.
7. ATP (adenosine triphosphate) has three phosphates.
8. Plants store extra energy as starch.
9. True. Pigments absorb certain wavelengths and reflect the ones we perceive as color.
10. ADP (adenosine diphosphate) has two phosphates.
11. A heterotroph is an organism that cannot make its own food and must obtain energy by consuming other organisms.
12. Plants reflect green light and do not absorb it well.
