B. gravity causes auxins to accumulate on the lower side of roots.
C. It depends on more rapid elongation of some cells than others
D. It is mediated by auxin as for phototropism
E. All of the above

What is the growth of the plant part towards the earth called?
The growth of a plant part towards the Earth is called gravitropism. This is a plant's response to gravity, where roots grow downward (positive gravitropism) and stems grow upwards (negative gravitropism).
What benefit is there for a plant's shoots to have positive gravitropism?
Positive gravitropism in a plant's shoots ensures that they grow upwards, toward light, which is essential for photosynthesis. This upward growth helps maximize the plant's exposure to sunlight, enhancing its ability to produce energy and nutrients. Additionally, by growing away from the soil, shoots can access better air circulation, which is crucial for gas exchange. Overall, positive gravitropism supports the plant's survival and growth in its environment.
Which part of the plant shows a positive response to gravity?
The roots of a plant show a positive response to gravity by growing downwards in the direction of gravity, a process known as gravitropism. This helps the roots to anchor the plant securely in the soil and absorb water and nutrients effectively.
What kind of tropism is exhibited by a growing plant stem?
Positive phototropism, where the plant stem grows towards a source of light.
What kind of tropism do roots play?
Gravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia
What would happen to a plant if all its parts had a positive response to gravitropism?
the plant would die out
What is the growth of the plant part towards the earth called?
The growth of a plant part towards the Earth is called gravitropism. This is a plant's response to gravity, where roots grow downward (positive gravitropism) and stems grow upwards (negative gravitropism).
Do plants grow downwards?
No, plants do not always grow downward. Plant roots always grow downward due to positive gravitropism or positive geotropism. Plant shoots always grow upwards due to negative gravitropism or negative geotropism.
What benefit is there for a plant's shoots to have positive gravitropism?
Positive gravitropism in a plant's shoots ensures that they grow upwards, toward light, which is essential for photosynthesis. This upward growth helps maximize the plant's exposure to sunlight, enhancing its ability to produce energy and nutrients.

A change in the direction a plant grows in response to gravity?
This change in direction is called gravitropism. Plants respond to gravity by growing roots downward (positive gravitropism) and shoots upward (negative gravitropism). This mechanism helps plants optimize their growth by maintaining stable positions in relation to gravity.
What kind of tropism is exhibited by a growing plant stem?
Positive phototropism, where the plant stem grows towards a source of light.
Will time upside down help a plant to grow faster?
well the scientific meaning of it is no because of gravitropism. gravitropism is the force of gravity on plant. dont know what gravitropism is: wikipedia search: gravitropism.

Gravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia
The response of roots growing downward is an example of what?
The response of roots growing downward is an example of gravitropism, also known as geotropism. This is a plant's natural reaction to gravity where the roots grow towards the Earth to anchor the plant and absorb water and nutrients.
How does gravitropism help a plant to survive?
Gravitropism is the growth response of a plant to gravity, enabling it to orient its roots and shoots appropriately. Roots exhibit positive gravitropism, growing downward to anchor the plant and access water and nutrients, while shoots demonstrate negative gravitropism, growing upward to maximize light exposure for photosynthesis. This orientation enhances the plant's ability to thrive in its environment, ensuring efficient resource utilization and overall survival. By adapting to gravitational forces, plants can maintain structural stability and optimize growth.
What is the meaning of gravitropism?
Gravitropism is when the roots grow deeper into the soil with the force of gravity pushing it. Wow, I'm in elementary school and my first person ever asking me something. It's a pleasure answering your question. I wish you luck on what ever your doing.
