What is a change in the way a plant grows in response to sunlight?
Phototropism is the change in the way a plant grows in response to sunlight. This process involves the plant bending towards the light source to optimize its exposure to sunlight for photosynthesis.
What is the stimulus of a plant growing toward light?
The stimulus for a plant growing toward light is phototropism, which is the plant's growth response to light direction. In this process, cells on the side of the plant that is away from the light elongate more than those on the side facing the light, causing the plant to bend toward the light source. This response is primarily regulated by the plant hormone auxin, which redistributes in response to light, promoting growth on the shaded side. This adaptation helps maximize light absorption for photosynthesis.
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.
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.
Which of these terms can be defined as a plant's response to light?
Phototropism refers to a plant's response to light, where the plant grows toward or away from a light source.
What causes thigmotropism?
It is the directional response of a plant organ to physical contact with a solid object.
What do you call a plant response?
Phototropism, where the plant "turns" to arrange its leaves for better exposure to light. This process is regulated by growth regulators in the plant. Photo = light Tropism from the Greek "trope" or turning. See picture
What cellular process causes a plant's leaves to swell?
lack of water
When A plant grows toward the light. The plant and action is an example of?
Phototropism is the plant's growth response towards light. It allows plants to maximize light absorption for photosynthesis by growing towards the light source. This process involves the plant hormone auxin, which causes cells to elongate on the shaded side of the plant, leading to bending towards the light.
What is a change in the way a plant grows in response to sunlight?
Phototropism is the change in the way a plant grows in response to sunlight. This process involves the plant bending towards the light source to optimize its exposure to sunlight for photosynthesis.
Which culprit originates an allergic response and causes Juan to sneeze when he sniffs the morning glory flower?
Harmless plant proteins
What is the growth of plant roots down word and shoots upward called?
Elongation of the meristematic tissue
Which process causes the leaves of a plant to become larger?
The process that causes leaves to become larger is called cell division and elongation, which is driven by the plant hormone gibberellin. This hormone promotes cell growth and expansion in the leaves, leading to an increase in their size.
How do tree branches grow downward?
Tree branches grow downward due to a process called gravitropism, where the plant's cells sense gravity and grow in response to it. This causes the branches to grow in a downward direction, helping the tree maintain its balance and stability.
What is plant growth in response to touch?
Plant growth in response to touch is called thigmotropism.
Can you explain how a plant that opens and closes responds to its environment"?
A plant that opens and closes in response to its environment does so through a process called tropism. This is when the plant's cells respond to external stimuli, such as light or touch, by changing their shape or orientation. For example, the opening and closing of a plant's leaves in response to light is known as phototropism. This allows the plant to optimize its exposure to sunlight for photosynthesis.
Which process causes they gradual change shown in the plant community?
Succession is the process that causes the gradual change in plant communities over time. It involves a series of stages where new species gradually replace existing ones, leading to a more stable and diverse ecosystem. This process can be triggered by disturbances such as fire, flooding, or human activities.
