tino4ka555 [31]

Answer:

$\boxed{\tt B. \ Conversion\ of\ light \ energy \ to \ chemical \ energy}$

Explanation:

This question asks us which process involves the chloroplast.

In plants, algae, and some bacteria, a process called <u>photosynthesis</u> occurs. This process takes place in the <em>chloroplasts. </em>In the process, the organism takes light energy from the sun, carbon dioxide, and water, and turns it into glucose and oxygen.

The glucose that is made becomes the food and energy for the organism. In another process, called cellular respiration, the sugar is turned into ATP, a kind of useable energy.

The best answer choice is B. Conversion of light energy to chemical energy. The chloroplasts convert light energy to sugar, and the sugar becomes chemical energy.
