Question

Yasmine is asked to describe the structural organization of chloroplasts. She writes the following sentence:

Answer 1

Answer:

C. Exchange the positions of "stroma" and "grana."

"A chloroplast contains thylakoid stacks, called grana, that are surrounded by fluid-filled stroma."

Explanation:

A dynamic biochemical process, photosynthesis, occurs within the chloroplasts of plants. Here, to form stable carbohydrates, light energy is transformed into chemical energy.

              6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2

Carbon Dioxide + Water + Light       Glucose + Oxygen

Chloroplasts are tiny, highly-folded, membrane-bounded organelles containing enzymes, pigments and other molecules that mediate photosynthesis. In the stack of grana,  pigments like chlorophyll, absorb light energy for the light-dependent reactions.
