What causes the light from far away galaxies to bend?
If the light from a distance galaxy passes near a massive cosmic object, then the gravity of that object will distort space-time. That will cause the light to bend.
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.
If light passes into a material where the speed of light is faster does the light bend torward or away from the boundry between the material?
If light passes into a material where the speed of light is faster, it will bend away from the boundary between the two materials. This occurs because light travels more slowly in denser materials, and when it exits into a less dense medium (where it travels faster), it refracts away from the normal line at the boundary. This behavior is described by Snell's law.
Which plant hormone causes plants to bend toward light?
Auxin is the plant hormone responsible for causing plants to bend towards light. This process, called phototropism, occurs when there is a higher concentration of auxin on the shaded side of the plant, causing cells to elongate and the plant to bend towards the light source.
What is the process of plant growing towards darkness?
The process of plants growing towards darkness is known as "negative phototropism." While most plants grow towards light (positive phototropism), certain species exhibit a tendency to grow away from light sources, often in search of more favorable conditions or to escape unfavorable light. This response is mediated by plant hormones like auxins, which redistribute unevenly, causing the plant to bend away from the light and grow towards darker areas. This behavior can help plants optimize their chances of survival in competitive or shaded environments.
When plants bend toward the light what is it called?
Plants bend as they need light for photosynthesis. Its scientific term is phototropism.
Which of the following seedlings will probably bend toward the light?
Seedlings typically bend toward light in a phenomenon known as phototropism. Of the options provided, the seedling that is most likely to bend toward the light is the one with the geotropism. Geotropism is the response of a plant to gravity, causing its roots to grow downward and shoots to grow upward, steering away from the light source.
How light brings about tropic movement in the stem and root of a flowering plant?
photo tropism is the growth-response to light in a plant. stems exhibit positive photo tropism while most roots exhibit negative photo-tropism
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.
When light is traveling fast in a medium which way will it bend?
When light travels fast in a medium, it tends to bend away from the normal. This is known as refraction. Refraction occurs due to the change in speed of light as it moves from one medium to another, causing it to bend towards or away from the normal depending on the speed change.
What causes the light from far away galaxies to bend?
If the light from a distance galaxy passes near a massive cosmic object, then the gravity of that object will distort space-time. That will cause the light to bend.
Define the word tropism please help need it for an exam on Friday help aye bezzi?
an orientation of an organism to an external stimulus, as light, esp. by growth rather than by movement. like phototropism...plants bend to where the light is showing geotropism...plants roots grow downward with respect to the force of gravity hydrotropism....plant roots strench down to where water is negative tropism....when a plant that is in the shade bends to where the sunlight is myspace.com/lil_cc_princess
What cause plants to bend towards the light?
Plants bend towards light through a process called phototropism, which is driven by the unequal distribution of the plant hormone auxin. When light shines on one side of a plant, auxin accumulates on the shaded side, promoting cell elongation there. This growth causes the plant to bend towards the light source, optimizing its ability to photosynthesize. This adaptive response helps maximize light absorption for energy production.
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).

What makes plants bend?
the sun makes plants bend because it happened.
If light passes into a material where the speed of light is faster does the light bend torward or away from the boundry between the material?

Is the amount of bending influenced by the amount of time seedlings spend in the light?
Yes it is, the plants need for sunlight will bend the stem to increase its reception of light.
