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.
What else can I help you with?
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.
Which functional group does Abscisic acid have?
Abscisic acid has a carboxylic acid functional group.
Which plant hormones affect(s) development in the plant body?
Several plant hormones play crucial roles in development, including auxins, cytokinins, gibberellins, abscisic acid, and ethylene. Auxins promote cell elongation and apical dominance, while cytokinins stimulate cell division and shoot formation. Gibberellins are involved in seed germination and stem elongation, whereas abscisic acid helps regulate stress responses and dormancy. Ethylene influences fruit ripening and leaf senescence, collectively coordinating various developmental processes in plants.
What are the hormones present naturally in plants?
Absisic Acid- prevents growth and can cause leaf drop in some plantsEthylene- promotes fruit ripening and leaf dropCytokinins- promote differentiation and overall growth of the plantGibberellins- promote seed germination and budding in flowersAuxin- promotes lateral growth
What is in abscisic acid?
Abscisic acid is a plant hormone that plays a role in seed dormancy, germination, and stress responses. It regulates various physiological processes such as stomatal closure, seed maturation, and growth inhibition. Abscisic acid is synthesized in response to environmental stresses like drought, high salinity, and cold temperatures.
What is The hormone that keeps seeds from germinating?
abscisic acid
Does abscisic acid slow down growth?
yes
What are the 4 hormones used in horticulture?
The 4 hormones commonly used in horticulture are auxins, cytokinins, gibberellins, and abscisic acid. These hormones play key roles in plant growth and development, including cell division, shoot elongation, fruit development, and stress responses. By manipulating the levels of these hormones, horticulturists can control various aspects of plant growth and physiology.
Are there any industrial uses for abscisic acid?

Helps plants to become dormant in winter?
Abscisic acid
What type of osmotic environment was present to bring about the abscisic acid trigger?
Abscisic acid is triggered in response to a low water potential or water stress in the plant's environment. This osmotic environment causes the plant to produce and release abscisic acid, which helps regulate processes related to water conservation and stress response.
