Auxins
the auxins in the plant and the gravity
Plants have things in them called auxins. The lighter the place, the more auxins a plant will have. Auxins make the plant's cells stretch towards the light, making the plant bend and get taller.
The control of plant growth is a reason why auxins are in weed killers. The hormone in question makes plants grow at the appropriate rate within the proper timespan. Weed killers try to alter, slow down or speed up growth to the detriment of the undesirable, unfamiliar vegetation in question.
A herbicide that only kills certain types of plants as opposed to others. Most selective herbicides kill dicotyledonous plants, and do not affect monocotyledonous plants. See related question

Auxins are substances that promote stem elongation and inhibit the growth of lateral buds. They are produced in the stem buds and root tips of plants.

Auxins are chemicals exist in plants to stimulate growth. When sunlight hits one side of the stem of a plant, the auxins move away and down from the sunlight. This causes the 'dark' side of the stem to grow faster than the 'lighted' side, which causes the stem to lean towards the source of the light.
Auxins are primarily transported in the phloem tissue of plants. They can move in both directions within a plant using the phloem, allowing for the long-distance signaling that regulates plant growth.
