When agriculture started people also started to settle down in groups. This led to the development of civilization and in modern day cities and towns. The first agricultural practices were started beside the river banks due to the reason that the soil was very fertile and water for irrigation was also easily available. </span>
Answer: NADPH and ATP
Explanation:
The mechanism of photosynthesis can be divided into two phases, light reaction, and carbon fixation. During the light reaction, photosynthetic pigments absorb radiant energy and undergo a series of photochemical reactions and convert the trapped energy into chemical energy which is stored in the form of NADPH and ATP. These two compounds constitute the assimilatory power. Light reaction is light dependent and it takes place in the grana of the chloroplast.
