In which two parts of a chloroplast does photosynthesis occur
wlad13 [49]

Answer:

Grana and stroma

Explanation:

Photosynthesis is the process by which plants make their organic food. This process occurs in the chloroplast of the cell. Grana and stroma are the two parts that are involved in photosynthesis.

Grana are stacks of thylakoid which increase the surface area for light absorption. It is the place where light-dependent reaction occurs. Stroma is the fluid that surrounds grana. It contains the enzyme which is required in photosynthesis.  It is the place where light independent reaction occurs.

Stroma is the place where synthesis of organic material from carbon dioxide and water occurs. Therefore the correct answer is grana and stroma.
