What plant hormone is responsible for most tropisms?
Gibberellins are growth hormones that control plant height and bud development.
Plants lean toward the light because of plant hormones called what?
A growth hormone called auxin.
What is the name of the chemical that controls plant growth?
The plant growth hormone Auxin is controlled by circadian rhythms within the plant. The discovery explains how plants can time their growth to take advantage of resources such as light and water, and suggests that many other processes may be influenced by circadian rhythms.
What hormone is a growth?
A growth hormone is a chemical that has effects on plant growth
What hormone is responsible for apical dominance?
Apical dominance is a concentration of growth at the tip of a plant shoot, where a terminal bud partially inhibits axillary bud growth by using hormones.
Which plant hormone produced in apical meristems inhibits the growth of axillary buds?
The class of hormones called "Auxins" have this affect on plants.
The first plant hormone to be discovered was a type of?
growth promoting plant hormone
What are the disadvantages of synthetic plant hormones?
A hormone synthesized (unnaturally made) by something other than a plant, but made for the plant. And the "artificially" hormone made to act as the natural plant hormone.
What are plant hormones and what are their functions?
Plant hormones affect how plants grow. Unlike animal hormones, plant hormones are organic molecules. They aid in plant growth and survival. Cellular events like division and cell morphology are driven by hormone levels. In plants, meristematic tissue is composed of cells that are actively growing. This is where one is expected to find a relatively large concentration of plant hormones. Also, one will find higher hormone levels in root tips Auxin speeds up growth on one side of the plant. The flowers lean toward the sunlight. Cytokinin stimulates the growth of roots and is added to the tips of cuttings before planting to increase the likelihood of them rooting.
How is plant growth controlled?
plant growth controlled by hormone called auxin which is found in roots and shoots and sunlight break down auxin answered by rasool ebrahimi
What two plant hormones that regulate plant growth and development?
Auxin controls the growth of the plant. Auxin in the roots of the plant inhibits growth whereas in the stems in the stems it encourages growth.
Is gibberellin a plant growth hormone?
true
