Auxins and giberellins are?
Auxins and gibberellins are plant hormones involved in regulating growth and development processes. Auxins are responsible for cell elongation, root formation, and apical dominance, while gibberellins promote stem elongation, seed germination, and flowering.
Where are gibberellins made?
Gibberellins are primarily synthesized in the shoot tips of plants, particularly in the young leaves and developing seeds. Once produced, gibberellins are then transported to various parts of the plant to regulate growth and development processes.
What is the effect do gibberellins have on stem?
They cause stems to grow longer due to an extended internode distance.
What is produced in meristems?
Meristems produce new cells for plant growth and development. These specialized tissues are responsible for generating all the above-ground and below-ground parts of a plant, including stems, leaves, and roots.
How do the effects of abscisic acid differfrom those of gibberellins?
Abscisic acid inhibits seed germination, induces stomatal closure, and promotes dormancy to conserve water in plants, whereas gibberellins promote seed germination, stem elongation, and flowering by stimulating cell division and elongation. Gibberellins also counteract the effects of abscisic acid by promoting growth and development.
What are the two types of plant hormones?
Auxins, cytokinins and gibberellins
Why do farmers hormones auxins and gibberellins in plant?
preventing from scencences
A plant that produces too little of the gibberellins might?
A plant that produces too little gibberellins may exhibit stunted growth, reduced stem elongation, and delayed flowering. Gibberellins are important plant hormones that regulate various developmental processes such as germination, stem growth, and flowering.
What plant hormone is responsible for most tropisms?
Gibberellins are growth hormones that control plant height and bud development.
How does gibberellins cause plant growth by stimulating what?
Gibberellins stimulate plant growth by promoting cell elongation and division in stems and leaves, leading to increased plant height and overall growth. They also activate the germination of seeds by breaking dormancy and promoting seedling growth.
What substances help plant growth?
Growth regulators help in plant growth. Examples are auxin, gibberellins, cytokinens etc.
What hormone is lacking in dwarf varieties of plants?
Gibberellin hormone is usually lacking in dwarf varieties of plants. Gibberellins are a group of plant hormones that regulate plant growth and development, and a deficiency can result in reduced elongation and a dwarf phenotype in plants.
Both cytokinins and gibberellins promote plant growth. Compare the ways in which these hormones stimulate growth.?
Cytokinins promote cell division and growth mainly in lateral buds and roots, leading to bushier plants. Gibberellins, on the other hand, primarily promote stem elongation and leaf expansion by stimulating cell elongation. Both hormones work together to regulate various aspects of plant growth and development.
Which plant hormone is responsible for breaking the dormancy cycle in plants?
Gibberellins are plant hormones that are responsible for breaking dormancy in seeds by promoting germination and growth. They stimulate seed germination and help in initiating growth processes in plants.
Auxins and giberellins are?
Auxins and gibberellins are plant hormones involved in regulating growth and development processes. Auxins are responsible for cell elongation, root formation, and apical dominance, while gibberellins promote stem elongation, seed germination, and flowering.
Gibberellins cause plant growth by stimulating?
Gibberllins cause plant growth by stimulating cell division. It causes growth in the stems and leaves.
What of the plant hormones influence parthenocarpy?
Auxins and gibberellins are plant hormones that can influence parthenocarpy, the production of fruit without fertilization. Auxins promote cell division and expansion, while gibberellins regulate fruit growth and development, both of which are important for parthenocarpy to occur.
