The chemical that promotes phototropism is?
Auxin is the chemical that promotes phototropism in plants. Auxin is produced at the tips of plant stems and helps cells elongate, causing the plant to bend towards a light source.
What is the effect of auxin on different parts of plants?
Auxin is a plant hormone that regulates growth and development by promoting cell elongation, particularly in stems and roots. In stems, auxin facilitates upward growth by concentrating on the side away from light, causing the plant to bend towards the light (phototropism). In roots, auxin influences downward growth and root development, but in higher concentrations, it can inhibit root elongation. Overall, auxin plays a crucial role in coordinating directional growth and responses to environmental stimuli.
What causes plant stems to exhibit positive response to light?
Plants exhibit positive response to light through phototropism, a process regulated by the hormone auxin. When one side of the stem is exposed to light, auxin accumulates on the shaded side and promotes cell elongation, causing the stem to bend towards the light source. This helps the plant maximize light absorption for photosynthesis.
Why do plant stems grow toward the light and the roots toward the ground?
If you grow the Stem in the dark then it wouldn't be healthy/wouldn't grow, and if you grow the Root not towards the ground then it will be wobbly and go ON the ground INSTEAD of going into the ground and wouldn't grow :)
How do plant stems response to light?
Plant stems respond to light through a process called phototropism, where they grow towards a light source. This response is mediated by the hormone auxin, which accumulates on the shaded side of the stem, causing cells to elongate and bend the stem towards the light. This allows plants to optimize their exposure to light for photosynthesis.

How do plant hormones control the growth of roots and shoots?
Auxin controls the growth of the plant. Auxin in the roots of the plant inhibits growth whereas in the stems in the stems it encourages growth.
What are some examples of phototropism?
IN PLANTS plant stems grow towards light (Auxins are plant growth hormones. They work by making cells grow longer, and divide more.) The Auxin collects on the dark side of the shoot; therefore, more growth will occur on this side of the plant. Therefore, the shoot will gradually lean towards the sun , important for photosynthesis. They need light for photosynthesis
What is the plant hormone that causes plant leaves and stems to exhibit positive phototropisms called?
auxin
Gibberellins are hormones that are used to enlarge the stems of fruits and vegetables which hormone's growth does it promote?
Auxin

Over time the stems of the plant curve toward the light coming in the window this process is called?
phototropism
What causes a stem to bend towards light?
this is called a tropism, where the growth of a plant in a particular stimulus, (light in this case). A chemical called auxin causes the elongation of cells. When a shoot is illuminated from one side, auxin is transported down the shaded side. This shaded side then elongates more rapidly than the illuminated side, causing the shoot to bend towards the light. Also the stimulus(light) must be detected by the tip of the plant shoot or root.
How do plant stems response to light?
Plant stems respond to light through a process called phototropism, where they grow towards a light source. This response is mediated by the hormone auxin, which accumulates on the shaded side of the stem, causing cells to elongate and bend the stem towards the light. This allows plants to optimize their exposure to light for photosynthesis.
Stems and leaves grow using positive what?
stems and leaves grow using positive phototropism. That means growing towards the source of light. Mostly we reffer to the sun in this case. Even so, stems and roots can as well grow away from the source of light, that is negative phototropism.
