Accepted Answer

Chloroplast

Question 7

What is the main function of stomata in plant leaves?

Accepted Answer

Allow gas exchange (CO$$_2 in$$, O$$_2$$ out)

Question 8

Which of the following best describes the role of chlorophyll in photosynthesis?

Accepted Answer

It absorbs light energy

Question 9

Which of the following is true about the light-dependent reactions of photosynthesis?

Accepted Answer

They produce ATP and NADPH

Question 10

Accepted Answer

The thylakoid membrane

Question 11

Which of the following best explains why photosynthesis is considered an endergonic reaction?

Accepted Answer

It requires an input of energy from sunlight

Question 12

Which of the following is a correct summary of the Calvin Cycle?

Accepted Answer

$$CO_2 is $$fixed and reduced to sugar using ATP and NADPH

Question 13

Which of the following best describes the relationship between wavelength and energy in the electromagnetic spectrum?

Accepted Answer

Shorter wavelength means higher energy

Question 14

Which of the following is the most inclusive group of organisms that perform cellular respiration?

Accepted Answer

All organisms

Question 15

A scientist exposes a plant to only green light. What is the most likely effect on the rate of photosynthesis, and why?

Accepted Answer

It will decrease, because green light is mostly reflected by chlorophyll

Question 16

Accepted Answer

Increased frequency of wildfires and droughts

Question 17

Which of the following best describes the function of photoautotrophs in the biosphere?

Accepted Answer

They produce organic molecules from inorganic molecules

Question 18

During the light reactions of photosynthesis, what is the primary source of electrons for the electron transport chain?

Accepted Answer

H$$_2O$$

Question 19

Which of the following best explains why plants are considered the 'producers' of the biosphere?

Accepted Answer

They convert inorganic molecules into organic molecules using sunlight

Question 20

A plant is placed in a sealed container with only water and sunlight provided. Which gas will accumulate in the container as a result of photosynthesis?

Accepted Answer

Oxygen
