It depends on how you look at it. However maybe we can say it is a messenger or "control packet" where a cell or a tissue tells another cell or tissue, for instance on the opposite side of the plant, to do something to fulfill a need or begin another part of the plant life cycle.
For instance, it has been my speculation that gibberellin is made by cells when they are experiencing deficiencies in sugar. So roots that are experiencing sugar shortages, might make gibberellin.
The various things that gibberellin does, are attempts to fix this problem. So gibberellin stops root growth because roots don't make sugar they just use it; gibberellin causes the release and dissolving of stored starch in cells; it causes the shoot to lengthen, presumably because the plant thinks it's being shaded; and it stops the senescence or dieing off of leaves and shoot branches, as sugar is made in the shoot and every bit helps, at least in the beginning of such a crisis.
Scientists have found that there might be a complex starch that acts as a signal for a plant to begin flowering. Say if the root released that, it might travel to the buds in the shoot and start the flowering process.
A hormone synthesized (unnaturally made) by something other than a plant, but made for the plant. And the "artificially" hormone made to act as the natural plant hormone.
The plant hormone ethylene.
Yes however auxin is a plant hormone
growth promoting plant hormone
Giberallin is a hormone.It is a plant hormone.
abiscisic acid is a plant hormone which stops the plant from growing
Auxin is a hormone that is found solely in plants.
That hormone is Ethylene.Fomula of it is C2H2
A growth hormone is a chemical that has effects on plant growth
Plant hormone is a chemical that regulates plant growth. These chemicals are produced with in plant and are present in very low concentration. Examples are auxins, Gibberellins, cytokinin's etc.
kinetin is a plant hormone that, when paired with auxin (another plant hormone), results in prolific growth of undifferentiated cells.
auxin. which is a hormone in the plant which stimulates cell division and cell elongation.Auxin
the hormone commonly present in plant for tea plantation are auxins
The plant hormone that stimulates the final stages of cell division is cytokinins
the plant hormone Ethylene
Its definitly animal and a mammal but I'm not sure which.
An Imak hormone. It comes from the shatif of the nucleus.
The plant hormone that is responsible for breaking the dormancy cycle in plants is gibberellins. The endosperm of a plant forms the food supply for the new sporophyte plant.
Gibberellic acid, or GA3, is a simple gibberellin, pentacyclic diterpene acid. This plant hormone promotes the elongation and growth of plant cells.
this acid helps in doing nice functiong of our body and is useful
