How is sunlight used in photosynthesis?
sunlight controls the amount of water in plant cells.
sunlight is a nutrient for plants.
sunlight is converted to chemical energy.
sunlight breaks cell walls to allow energy in and out.

Sunlight is needed for photosynthesis because the solar energy is what is converted to chemical energy by the plant's chloroplasts.

Explanation:

This energy is necessary for the production of glucose, which provides usable energy for the plant. The chloroplasts contain the green pigment chlorophyll, which absorbs the sun's light.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
