The light dependent reactions take place in thea)matrix of the mitochondria.
b. stroma of the chloroplast.
c. stroma of the mitochondria.
d. thylakoid of the chloroplast.

The correct answer is D) Thylakoid of chloroplast.

Light dependent reaction is the first phase of photosynthesis that takes place in the thylakoid membrane of the chloroplast.

In this phase, energy from sunlight is captured by chlorophyll and converted into chemical energy in the form of ATP and NADPH.

This is further utilised in the formation of carbohydrate (glucose) during the next phase that is the light independent phase.

Thus, option D) is the right answer.

the answer is c.) there is a warm front in region a and a stationary front in region b.
