In phototropism, plant hormones control the growth and development of plants due to light.
For example, in positive phototropism, auxin, a hormone, speeds up the rate at which plant cells grow. It builds up on the shadier side of a plant, causing those cells to grow faster than the cells on the sunny side of the plant. With longer cells on one side than the other, the stem bends toward the light.
What else can I help you with?
Does all plants use phototropism to grow?
No, not all plants use phototropism to grow. Phototropism is the growth response of plants to light, where they grow towards a light source. While many plants exhibit phototropism, there are some plants that may not rely heavily on this mechanism for growth.
What is a sentence using the word phototropism?
Phototropism is when plants grow towards light.
What is a sentence example of phototropism?
We observed the phototropism of our plants.
What is it called when plants lean towards the sun?
expanentional growth
The plants lean toward the sun is what word?
The plants lean towards the sun is an example of positive phototropism, where plants grow towards a light source.
When plants bend toward the light what is it called?
Plants bend as they need light for photosynthesis. Its scientific term is phototropism.
Comparition and contraction between phototropism and gravitropism?
If I am not mistaken, phototropism is when plants grow towards the sun. Gravitropism is when plants grow towards the ground.
What examples of plants is phototropism?
The Sunflower plant inflorescence at the time of anthesis move toward the sun due to phototropism.
Do plants exhibit phototropism by growing towards light sources?
Yes, plants exhibit phototropism by growing towards light sources. This is a natural response that allows plants to maximize their exposure to sunlight for photosynthesis.
Phototropism in plants is mediated by what plant growth substance?
auxin
What is the role of phototropism?
The role of phototropism is to provide more energy for the plant. This gives it more energy because when photosynthis developes the light into energy, it actually needs light! Shocking. (Not really) So phototropism makes the plant lean twoard the sun.
The name of the response of plants to light?
a "tropism"; geotropism for response to gravity and phototropism for response to light
