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.
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.
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.
What is it call when Leaf blades grow larger as a result of cell division?
This process is called leaf expansion, where the leaf blades increase in size due to cell division and cell enlargement. This growth is often regulated by hormones such as auxins and gibberellins.
What is the functiOns of gibberellins?
Growth Promoters with the plants Hormones (regulators)
Why do farmers hormones auxins and gibberellins in plant?
preventing from scencences
What are the two types of plant hormones?
Auxins, cytokinins and gibberellins
What is the difference between abscisic acid and gibberellins?
Gibberellins are chemical substances that were isolated first from a fungus. Abscisic acid is the substace that keeps seeds from sprouting and buds from developing during the winter.
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 might a florist spray his plants with to encourage buds to open?
Gibberellins
What are some commercial uses of gibberellins?
Gibberellins are used in agriculture to promote plant growth, increase fruit size, and induce seedless fruit formation in crops such as grapes and citrus fruits. They are also used in the production of malting barley to promote uniform germination. Additionally, gibberellins are used in the floral industry to induce flowering in certain plants out of their normal blooming season.

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.
Gibberellins are hormones that are used to enlarge the stems of fruits and vegetables which hormone's growth does it promote?
Auxin
