What happens when the stomata on a plant's leaves are open?

a.) oxygen and water escape the leaves and carbon dioxide enters it.
b.) sugars and nutrients are transported up to the leaves from the roots.
c.) sunlight is able to enter the leaves and photosynthesis takes place.
d.) water enters the leaves and carbon dioxide escapes from the leaves.

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.

c. heat from the poles back down towards the equator.
