what is the primary function of photosynthesis?
a. to convert light energy into chemical energy in the form of glucose
b. to synthesize proteins in plants
c. to break down glucose into atp
d. to release carbon dioxide and water

which part of the plant cell contains the pigments necessary for capturing light energy?
a. thylakoids in the chloroplasts
b. nucleus
c. mitochondria
d. cell membrane

what are the two main stages of photosynthesis?
a. light - dependent reactions and light - independent reactions
b. cellular respiration and fermentation
c. glycolysis and the citric acid cycle
d. electron transport and fermentation

what is the main product of the light - dependent reactions?
a. glucose
b. water
c. oxygen
d. carbon dioxide

where does photosynthesis primarily take place in plant cells?
a. mitochondria
b. nucleus
c. chloroplasts
d. cytoplasm

what is the primary purpose of the light - independent reactions?
a. to capture light energy
b. to convert carbon dioxide into glucose
c. to release oxygen into the atmosphere
d. to break down glucose into atp

what is the role of carbon dioxide in photosynthesis?
a. it is used to produce glucose during the light - independent reactions
b. it captures light energy in the chloroplast.

Explanation:

• For the first question, photosynthesis converts light energy into chemical - energy in glucose.
• For the second, thylakoids in chloroplasts have pigments for light - energy capture.
• For the third, the two main stages are light - dependent and light - independent reactions.
• For the fourth, oxygen is the main product of light - dependent reactions.
• For the fifth, photosynthesis occurs mainly in chloroplasts.
• For the sixth, light - independent reactions convert carbon dioxide into glucose.
• For the seventh, carbon dioxide is used to produce glucose in light - independent reactions.

3. a. Light - dependent reactions and light - independent reactions
4. c. Oxygen
5. c. Chloroplasts
6. b. To convert carbon dioxide into glucose
7. a. It is used to produce glucose during the light - independent reactions
