Question

question 8 of 25
which phrase describes a feature of chloroplasts that aids in the production
of sugar through photosynthesis?
the student used potting soil to represent land, water to

a. a rigid internal structure
b. a green pigment called chlorophyll
c. a large network of membranes
d. enzymes for breaking down proteins

Explanation:

To determine the correct answer, we analyze each option:

• Option A: A rigid internal structure (like a cell wall) is not a feature of chloroplasts aiding in photosynthesis. Chloroplasts are organelles, and their internal structure for photosynthesis is related to membranes and pigments, not rigidity.
• Option B: Chlorophyll is the green pigment in chloroplasts that absorbs light energy, which is essential for the light - dependent reactions of photosynthesis that ultimately lead to sugar production. This is a key feature aiding in photosynthesis.
• Option C: While chloroplasts have a network of membranes (thylakoids), the description "a large network of membranes" is too vague and does not directly point to the function of sugar production as clearly as the presence of chlorophyll.
• Option D: Enzymes for breaking down proteins are related to processes like digestion or protein metabolism, not photosynthesis which is about sugar production from carbon dioxide and water using light energy.

Answer:

B. A green pigment called chlorophyll
