Q: which of the following statements best describes the relationship that exists between the formation of glucose and its use?

1: plants contain chloroplasts to undergo photosynthesis and make glucose directly, but they also use mitochondria for cellular respiration.

2: plants contain chloroplasts to undergo photosynthesis and make glucose directly, so they do not need mitochondria.

1. Plants contain chloroplasts to undergo photosynthesis and make glucose directly, but they also use mitochondria for cellular respiration.

Explanation:

The end product of both photosynthesis and cellular respiration is to provide energy but each of these processes is essential in its own way and necessary for proper maintenance of plants and animals.

In cellular respiration, glucose and oxygen combine to form energy in the form of ATP along with water and carbon dioxide.

In photosynthesis, carbon dioxide and water molecules undergo series of reactions under the presence of light energy to produce glucose and oxygen.

Both these processes release different, essential molecules for energy.
