Which causes plants to respond positively to sunlight?
Auxin's cause plants to respond positively to sunlight. Auxin's were the first major plant hormone to be discovered. Auxin's, produced in the meristems of plants, are responsible in promoting cell elongation.
What have scientists researched about the effect saltwater has on the growth of plants?
Scientist have discovered that the inner layer of tissue in the branching root is sensitive to salt and activate a stress hormone. This hormone stops root growth.
What is the function of acetic acid in mitosis?
Acetic acid acts as a plant growth hormone. Plants that have been treated with acetic acid typically have more cells that are in the mitosis phase than untreated plants.
Does green light affect plants?
Green light does affect plants, but it doesn't really provide much help in the plants' growth. Plants that are green absorb all the colors of light except the color green, which is reflected off the plant. This is why we see the plant as green.
Why are plant hormones used?
Growing cuttings. Cuttings develop much bigger root systems if they are dipped in hormone rooting powder or planted in rooting compound containing growth hormone - making it possible to clone plants quickly and cheaply. * Producing fruit without seeds. To do this, growth hormones are sprayed onto unpollinated flowers to make them grow fruit without fertilisation. * Ripening fruit. The plant hormone ethene is sprayed on fruits to make them ripen fast and all at the same time before harvesting. Bananas are harvested before they are ripe to reduce damage to them during transport, and then sprayed with ethene to ripen them. * Increasing the size of fruit. For example, grapes are sprayed with the hormone gibberellin to increase the size of the fruit. * Controlling weeds. Some synthetic weed killers which selectively kill unwanted plants contain growth substances that speed up the metabolism. As a result weeds like dock and dandelion grow so fast that their food and water supply cannot keep up, so they run out of energy and die
What is the growth hormone that stimulates plants elongation?
auxin
What Is the Growth hormone that Stimulates plants Cells elongation called?
auxin
How do plants grow up when gravity pulls everything down?
Humans grow too, yet we are pulled down. Plants, like most living organisms, grow by cellular reproduction. This replicates cells, making a plant larger. A hormone called auxin stimulates cell growth. The hormone is gravotropic, which means in plant shoots, it stimulates cell growth upwards, the opposite way in which gravity is forcing the plant.
How does phosphate affects plant growth?
In plants, phosphate stimulates root growth and helps prevent disease.
Why is abscissa acid know as stress hormone in plants?
Abscisic acid stimulates the closure of stomata in the epidermis and increases the tolerance of plants to various kinds of stresses.therefor it is called as the stress hormone
What is the site of primary growth for plants?
one answer: cell growth, which is caused by photosynthesis.
What is the growth of plants root downward and shoot upward called?
Elongation of the meristematic tissue
What hormone causes plants to grow toward light?
Auxin is a chemical which makes plants grow faster.Specifically, the chemical in question can be described as a plant hormone or phytohormone to regulate growth. The terms comes from the Greek word αυξειν (auxein) for "to grow, to increase." Auxin may occur naturally -- often in cooperation with the plant hormone cytokinin -- or synthetically.
Which causes plants to respond positively to sunlight?
Auxin's cause plants to respond positively to sunlight. Auxin's were the first major plant hormone to be discovered. Auxin's, produced in the meristems of plants, are responsible in promoting cell elongation.
Does the color of light used on plants effect how well they grow?
Does the color of light effect how well plants grow?
Where are auxins produce?
Auxins are substances that promote stem elongation and inhibit the growth of lateral buds. They are produced in the stem buds and root tips of plants.
What have scientists researched about the effect saltwater has on the growth of plants?
Scientist have discovered that the inner layer of tissue in the branching root is sensitive to salt and activate a stress hormone. This hormone stops root growth.
