Question

what is main site of photosynthesis in plants

Answer 1

$\textbf{Chlorophyll of the leaves}$ are the main sites of photosynthesis.

" Photosynthesis "

It is the process by which green plant and some other organism use sunlight to synthesize nutrients from carbon dioxide and water.

The main product form here is glucose and by products are oxygen and water.

Here it takes place in chlorophyll and I'm presence of sunlight.

There are two stages of photosynthesis :

1. Light reactions :

It occurs in the grana where photon are absorbed so as to excite electrons of chlorophyll to a higher energy level. These activated elctrons are harnessed to form ATP from the ADP and reduce NADP to NADPH. Wayer ia also spotted here and oxygen is released.

2. Dark reactions :

Calvin cycle occurring in chlorophyll here carbon combine with 5-carbon sugar called ribulose biphospahte. This unstable compound breaks down into 3-carbon compound. This then forms glucose.

• chloroplasts

The Cell. All green parts of a plant, including green stems and unripened fruit, have chloroplasts, but the leaves are the major sites of photosynthesis in most plants (FIGURE 10.2)..
