Questions: The process of photosynthesis occurs primarily in a plant's leaves. What organelle is responsible for this process? Mitochondria The nucleus Ribosomes Chloroplasts

The answer is the fourth one (D): Chloroplasts.

Explanation for each option:

• Mitochondria: These organelles are responsible for cellular respiration, not photosynthesis. They convert chemical energy from food into a form that cells can use, which is ATP.

• The nucleus: This organelle contains the cell's genetic material and is responsible for controlling the cell's activities, but it does not directly participate in photosynthesis.

• Ribosomes: These are the sites of protein synthesis in the cell. They do not play a role in photosynthesis.

• Chloroplasts: These organelles are responsible for photosynthesis. They contain chlorophyll, the green pigment that captures light energy, which is then used to convert carbon dioxide and water into glucose and oxygen.

In summary, chloroplasts are the organelles responsible for the process of photosynthesis in plant leaves.
