2. which of the following cell structures is the site of photosynthesis?
o a. golgi apparatus
o b. mitochondria
c. chloroplasts
d. centrioles

The cell structure that is considered the site of photosynthesis is known as chloroplasts. Hence, option C is the correct answer.

Photosynthesis is a significant process that takes place in plants. The process in which light energy obtained from the sun is converted into sugar molecules for the utilization by plants cells is known as Photosynthesis.  

Photosynthesis occurs at chloroplasts. Some of the significant features of the chloroplasts are listed as follows:

Thus, we can conclude that the chlorophyll present in chloroplasts is vital for photosynthesis and hence, chloroplasts are the cell structure that acts as the site of photosynthesis. Therefore, option C is the correct answer.
