Answer:B. speeds up the growth of the plant on the shaded side

Explanation: plants have hormones.these hormones controls the activities of the plants by serving as specific chemical signals between cells. They are usually moved from where they are produced to the region of the plant where they act. Eg auxin, cytokinin, gibberellin etc

Auxin has the ability to cause enlongation in shoot cells and root . They cause the cells of plant to stretch. they are produced in the apical meristem,buds and leaves. They also causes the suppression of side buds.

When a plant is placed in a dark shade and a side is exposed to light, auxin gathers on the shaded part of the plant. This causes the cells in that area to enlongate and the plant bends towards the light.

Why are there more stomata in the bottom of leaves
Jobisdone [24]

Stomata play an important role in photosynthesis as they allow the plant to absorb carbon dioxide from the environment. In exchange, stomata allow oxygen, which is a waste product of photosynthesis, to be released. In the process, water vapor is also lost as the internal parts of the leaves are exposed. To reduce exposure, stomata are found on the underside of the leaves. They are protected from the sun as excessive heat can increase the rate of water vapor leaving and thus wither the plant. Stomata also have guard cells around the epidermis that close when too much water is being lost.
