|
|
|
________ is when a molecule of high concentration wants to go to an area of low concentration

reduces
|
|
|
What are the 5 classic PGRs?
|
Auxin, gibberellic acid, abscisic acid, ethylene, cytokinins
|
|
|
Auxin is responsible for what four functions in a plant?
|
Apical dominance, sink strength, reproductive growth and development, tropisms
|
|
|
What plant functions are Gibberellic acids responsible for?
|
Bolting, stimulate seed germination
|
|
|
What plant functions are Abscisic acid (ABA) responsible for?
|
Promotes seed dormancy, closure of stomata,
|
|
|
What plant functions does Ethylene have in a plant?
|
fruit ripening, leaf abscission, epinastic growth
|
|
|
what plant functions do Cytocinnins have in a plant?
|
cell division, and shoot development in tissue culture
|
|
|
Parthenocarpic fruit refers to what kind of fruit?
|
seedless fruit
|
|
|
This type of fruit can continue to ripen even after being picked, resulting from ethylene in the fruit.
