The ability of a plant to bend toward a light source is known as phototropism. The hormone in a plant stem auxincauses elongation. Light destroys auxin when it strikes the stem. Because auxin is still present on the shaded side of the stem, the cells on the darker side are able to elongate more than the cells on the lighted side, causing the plant to bend toward the light. Phototropism by sunlight is also called heliotropism. The TickleMe Plant will fold it leaves and bend it branches when Tickled

∙ 14y agoA plant's ability to make food depends on its ability to absorb enough light energy. So, many plants move-in the small ways that they can-toward the Sun or other light sources (a characteristic known as phototropism). Some plants hold their leaves flat and open during the day-to catch as many of the Sun's rays as possible-and close them at night. Other plants change the direction their leaves face throughout the day, following the path of the Sun as it moves across the sky. When a plant grows in uneven sunlight-with the light hitting just one side of the plant, let's say-chemical messengers called hormones will cause more stems and leaves to grow on the lighted side so that the plant can gather enough of the sunlight it needs to make food. Phototropism explains why houseplants turn their leaves toward windows, growing into lopsided shapes unless they are rotated once in a while.

What is phototropism what does have to do with plants?
Tropism is the growth response of a plant caused by a stimulus. Gravitropism is the growth response of plant to gravity. The roots grow downward towards gravity, which is called positive gravitropism. The stem and upper part of a plant grow upward, away from gravity, which is called negative gravitropism.
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.
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.
What makes tree trunks bend?
A tree always wants to grow toward the Sun (phototropism), and individual branches will grow toward the brightest location, as openings in a forest or stand. The most successful vertical branch can often become the main trunk. Constant winds can also force trunks to bend, as they will attempt to grow vertically despite being bent by wind.
What auxin is not stable in light?
auxins are not stable in light because it will degenerate the hormones.so,when light touches at one side of the coleoptile,auxins will move to the other side (less sunlight).this makes the shoot grow faster at the side which have more auxins and slower at the place where there are less auxins and this makes the shoot bend towards the light source =P
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.
When a plant grows toward the light what do you call it?
Its called phototropism. It's actually really cool, the shaded side's cells elongate, causing the plant to bend towards the sun
What meant by phototropic movement?
When concluded that auxin accumulated on the side of the plant away from the light. When auxin flowed in this direction, the cells of the apical meristem elongated on that side and caused the plant to bend toward the light as growth continued.
When plants bend toward the light what is it called?
Plants bend as they need light for photosynthesis. Its scientific term is phototropism.
Which plant hormone causes plants to bend toward light?

Why does a plant bend when a tall building is near it?
It wanna grow where the light is.
Why do the roots of plants bend away from sun light?
why roots of plant grow away from light
What is the difference between taxis and tropism?
Tropism: is the growth response of a plant that results from certain stimuli. Tropism can be positive, in which case the plant will bend toward the stimulus, or negative, in which case the plant will bend away from stimulus. Taxis: Taxis in animals is the responsive movement of going toward or away from an external stimulus.
What is phototropism what does have to do with plants?
Tropism is the growth response of a plant caused by a stimulus. Gravitropism is the growth response of plant to gravity. The roots grow downward towards gravity, which is called positive gravitropism. The stem and upper part of a plant grow upward, away from gravity, which is called negative gravitropism.
