The correct answer is chloroplasts. Photosynthesis is the process by which plants and other organisms convert light energy from the sun into chemical energy in the form of glucose. This process happens within specialized organelles called chloroplasts, which are only found in plant cells.
To determine the answer to this multiple-choice question, we need to understand where photosynthesis takes place in a plant cell. There are a few key organelles to consider: the nucleus, cell wall, chloroplasts, and ribosomes.
1. Nucleus: The nucleus is the central compartment of the cell that contains genetic material (DNA). While the nucleus plays a crucial role in controlling cell activities and reproduction, it does not directly participate in photosynthesis.
2. Cell wall: The cell wall is a rigid layer surrounding plant cells, providing structural support and protection. It helps maintain the shape of the cell but is not involved in photosynthesis.
3. Chloroplasts: Chloroplasts are the organelles in which photosynthesis occurs. They contain the pigment chlorophyll, which absorbs light energy required for photosynthesis. Inside the chloroplasts, light energy is converted into chemical energy, enabling the synthesis of glucose.
4. Ribosomes: While ribosomes are involved in protein synthesis within a cell, they are not directly related to photosynthesis.
Thus, the correct answer is "chloroplasts" because these organelles are essential in carrying out photosynthesis within a plant cell.
