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.
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.
Where is abscisic acid produced in a plant?
Abscisic acid is primarily produced in the chloroplasts of plant cells, as well as in other plant cell organelles such as the peroxisomes and cytosol. It is synthesized in response to various environmental stresses like drought, cold, and high salinity, and plays a crucial role in regulating plant growth and stress responses.
Light and carbon dioxide and what all affect the opening and closing of stomata?
Light, carbon dioxide levels, and the hormone abscisic acid are the main factors that influence the opening and closing of stomata. Light triggers stomatal opening by promoting photosynthesis, while increased levels of carbon dioxide and abscisic acid can cause stomata to close to prevent water loss. Temperature and humidity can also play a role in regulating stomatal movement.
Does the stomata close to keep the plant from losing water?
Yes, stomata can close to prevent excessive water loss through transpiration. This closure is controlled by factors such as humidity, light intensity, and the plant's water status.
Which functional group does Abscisic acid have?
Abscisic acid has a carboxylic acid functional group.
What is The hormone that keeps seeds from germinating?
abscisic acid
Does abscisic acid slow down growth?

Helps plants to become dormant in winter?
Abscisic acid
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.
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.

Do abscisic acid keeps seeds from sprouting and buds from developing during the winter?
yes
Are tomates an acid?
yes. in tomatoes there are some acids: citric acid, ascorbic acid (vitamin c), abscisic acid. pH of ripe tomatoes is about 4.2
