James took two pea plants, placing one in a dark closet and the other on a sunny window sill. both are located in air conditioned rooms. he then measure the growth of the pea plants after a week. which of the following best describes the purpose of this experiment?

a. to determine the effect of sunlight on plant growth

b. to determine the effect of air conditioning on plant growth

c. to determine the effect of lack of water on plant growth

d. to determine the effect of enclosed spaces on plant growth

Answer;

A. To Determine The Effect Of Sunlight On Plant Growth

Explanation;

-Plants get energy from light through a process called photosynthesis. This is how light affects the growth of a plant. Without light, a plant would not be able to produce the energy it needs to grow.

-This means the plants that was placed in dark lacked an exposure to light, thus it was not able to carry out photosynthesis or make nutrients for itself. unlike the plant that was exposed to sunlight. Therefore, the plant that was exposed to sunlight had a higher growth rate as it was able to carry out photosynthesis.

the fossil record provides evidence of a common ancestor to many species.
