Sheela wants to make a computer model of a land ecosystem. Part of her model simulates the chemical processes of photosynthesis that involve the creation of sugars. Which chemical processes are these?

The options to this question are missing, the options are:

A. the light-dependent reactions

B. the light-independent reactions

C. the dark reactions

D. the reactions in the mitochondria

The answer is A

Explanation:

Photosynthesis is a unique phenomenon carried out by cells of autotrophic organisms. Photosynthesis, which generally involves the synthesis of food in form of sugar, occurs in two distinct stages viz: light-dependent and light-independent stages.

These two processes are important to the overall result of the photosynthetic process. However, the light-dependent stage (needs light to occur) produces the energy needed for the synthesis of sugars. The light-dependent stage which takes place in the thylakoid membrane of the CHLOROPLAST synthesizes the NADPH and ATP molecules, which enters the light-independent reactions to be used to power (ATP) and provide electrons (NADPH) needed for the purpose of creating sugar (glucose).

Hence, the part of Sheela's model that is simulating the chemical processes of photosynthesis are the light-dependent reactions.
