Chlorenchyma cells are parenchymatous cells that perform photosynthesis in plants. These cells are specifically adapted for this function and contain chloroplasts, which are responsible for capturing light energy and converting it into chemical energy through the process of photosynthesis.

Chlorenchyma cells are found in the mesophyll of leaves, where they are closely packed together to form a continuous layer. They are also present in other green parts of the plant, such as the stems and fruits.

Here are some key characteristics of chlorenchyma cells:

1. Chloroplasts: Chlorenchyma cells contain a high concentration of chloroplasts, which are the organelles responsible for photosynthesis. The chloroplasts contain the pigment chlorophyll, which gives plants their green color and enables them to absorb light energy.

2. Large central vacuole: Chlorenchyma cells typically have a large central vacuole, which helps maintain the turgidity of the cell. This allows the chloroplasts to be positioned close to the cell surface, maximizing their exposure to light.

3. Thin cell walls: The cell walls of chlorenchyma cells are thin and flexible, allowing for efficient gas exchange and the movement of nutrients between cells.

4. Interconnected cytoplasm: Chlorenchyma cells are interconnected through plasmodesmata, which are small channels in the cell walls that allow for the exchange of materials and communication between cells.

5. Photosynthetic function: Chlorenchyma cells are responsible for producing glucose, the primary source of energy for plants. Through photosynthesis, they convert carbon dioxide and water into glucose and oxygen, using light energy absorbed by the chlorophyll.

Overall, chlorenchyma cells are highly specialized for photosynthesis and play a crucial role in the production of food and oxygen in plants. Their unique structural and functional adaptations enable them to efficiently capture and utilize light energy for the synthesis of glucose, supporting the growth and survival of the plant.

Answer is d because chlorenchyma is type of parenchyma which store chlorophyll pigment help in photosynthesis.
