Final answer:
D) Chloroplasts are involved in photosynthesis is the correct statement. Chloroplasts, found in plants and algae, contain chlorophyll and conduct photosynthesis. Their structure includes a double membrane and internal thylakoid stacks, instrumental for converting light energy into chemical energy.
Step-by-step explanation:
The correct statement regarding chloroplasts is that D) Chloroplasts are involved in photosynthesis. Chloroplasts are specialized organelles found in plant and algal cells, essential for the process of photosynthesis. During photosynthesis, these organelles capture light energy using a green pigment called chlorophyll and convert it into chemical energy, in the form of glucose, using carbon dioxide and water. Chloroplasts have a unique structure with a double membrane envelope and internal thylakoid membranes, where the light-dependent reactions of photosynthesis take place. These thylakoid membranes are organized into stacks known as grana, and the space surrounding the grana is the stroma, where the light-independent reactions occur. Unlike animal cells, only autotrophic eukaryotic cells such as those of plants and algae contain chloroplasts.
