APBIO-BMNJFP

Within the chloroplasts of plants, thylakoids are found in vertical stacks known as grana.

Which of the following BEST explains why this structural arrangement of thylakoids within chloroplasts evolved?

Plants with this trait lost less water via transpiration and could survive better in drier environments.

B

Plants with this trait could capture more photons and make more carbohydrates.

C

Plants with this trait were able to create a proton gradient without acidifying the stroma.

D

Plants with this trait were able to avoid photorespiration on hot dry days.
