A) Mesophyll cells B) Thylakoids C) Stomata D) Chloroplasts Answer: 3) Chlorophyll is found in which part of the plant cell? A) stroma B) cytoplasm C) thylakoid D) plasma membrane Answer: 4) The purpose of chlorophyll is to: A) absorb light. B) let CO2 enter the plant. C) make ATP. D) make NADPH. Answer: 5) Which of the following statements about photosynthesis is false? A) Sunlight excites electrons from chlorophyll, which are captured by ATP. B) In the light reactions, electrons eventually wind up on NADPH. C) Photosynthesis involves many redox reactions similar to the electron transport chain used during cellular respiration. D) During the light reactions, ATP and NADPH are synthesized. E) A waste product of the light reactions is 02. Answer:

Answer 1

QUESTION 1

In this case, remember that photoreceptor absorb a determined wavelength but they reflect the opposite color. If you are observing a red color in the leaf, the leaf is reflecting only the red color.

QUESTION 2

Stomata permit CO2 to enter the leaf and O2 to escape. In fact, these structures are involved in the gas exchange and transpiration of the plant.

QUESTION 3

Chlorophyll is found in the thylakoid
