There is a plant hormone called auxins. In a plant such as a sunflower, the auxins will distribute themselves on the dark side of the plant where they will cause the the expulsion of H+ ions decreasing the Ph of the cells on the dark side of the plant. This decrease in Ph will cause a weakening of the cell wall and swelling will occur ultimatly allowing the plant to move and organize itslef towards sun light.

Is tropism the movement of a plant towards or away from a stimulus?
Towards. As in, phototropism. The tendency of plants to grow towards light.
What is an example of a non growth plant movement?
An example of a non-growth plant movement includes the tendency of a plant to bend in the direction of light.
Why did coconut trees bend towards the sea?
phototrophism- the trees lean towards the area where they will bestreceivelight at a greater surface area. plus the sea reflects a lot of incoming light towards the trees
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 plants respond stimuli?
The stimuli that plants respond to include light, water and gravity. Plants grow towards light (phototropism). Also in some plants the flowers will follow the sun as it moves across the sky. Plant roots grow towards water (hydrotropism). Plant roots grow towards gravity/towards the centre of the earth (geotropism). Source(s): I'm a Biology teacher. this is bullcrap it is fake
What is the thing that plants do this towards the light?
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.
When plants bend toward the light what is it called?
Plants bend as they need light for photosynthesis. Its scientific term is phototropism.
Do convex lenses cause light to bend?
Yes, they make light bend inwards towards a focus point.
A ray of light traveling from air to water will bend which direction?
The ray will bend towards the normal.
How do plants grow towards light?
plants grow towards light because of something called photo-tropism. this is why they will grow towards light. Search up Phototropism on Google!
How is the role of auxin in the bending of stems toward light?
Auxins move from their source into the rest of the plant, where they stimulate cell elongation. A higher concentration of auxins accumulate in the shaded part of a stem and causes the plant to move towards the light.
Is tropism the movement of a plant towards or away from a stimulus?
Towards. As in, phototropism. The tendency of plants to grow towards light.
When light passes through a prism why does the light ray bend towards the base of the prism?
reflection
What types of mirrors bend light rays in towards each other?
convex
How does a plant grow towards the light?
Green plants respond to the stimulus of light. Most stems and leaves grow towards light. HINt: If you have never noticed a plant that has sat in a sunny window for to long always bends towards the light.
Why do the roots of plants bend away from sun light?
why roots of plant grow away from light
What is the purpose to how the stems grow?
Yes, they normally grow up and will bend towards light.
