['The primary physiological effect of auxin in plants is to stimulate the elongation of cells in shoot. ... ', 'The higher concentration of auxin on the shaded side causes the cells on that side to elongate more rapidly resulting in bending of the stem tip towards the unilateral light.']

Alpha Naphthalene Acetic Acid (ANAA) is a growth hormone used to enhance or regulate growth and development of a plant. It acts as a catalyst for the new roots and protects the newly marcotted plants from fungus and disease that may have been introduced during the process.

Plant hormones as signal molecules regulate cellular processes in targeted cells locally and when moved to other locations of the plant. They also determine the formation of the root, stem, leaf, and flower and facilitate the shedding of leaves and the development and ripening of fruits.

Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. Example: Indole Acetic Acid (IA). Auxin is a plant hormone produced in the stem tip that promotes cell elongation.

Arborio rice stimulates the production of enzymes and hormones, helps protect the tissues of your body, helps your body to function normally and restores health. It also aids in the transports nutrients from your digestive tract to other areas in your body by regulating the digestive processes your body goes through.

Overview. Apical dominance occurs when the shoot apex inhibits the growth of lateral buds so that the plant may grow vertically. ... The apical bud produces a hormone, auxin, (IAA) that inhibits growth of the lateral buds further down on the stem towards the axillary bud.

How do roots grow towards moisture? An uneven amount of moisture either side of a root produces more auxin on the side with more moisture. This inhibits growth on that side, causing the root to bend in that direction, towards the moisture.

The hormone adrenaline floods into your bloodstream, putting your body on high alert. Your heartbeat quickens, which sends more blood to your muscles. Your breathing becomes fast and shallow, so you can take in more oxygen. Your blood sugar spikes.

Ivy doesn't harm trees A negative effect that ivy can have on a healthy tree is reducing the tree's capacity to produce energy. If ivy climbs through a tree's canopy, it can smother the leafing branches, which would limit the tree's ability to photosynthesise.

Auxin herbicides stimulate a variety of growth and developmental processes when present at low concentrations at the cellular sites of action. However, with increasing concentration and auxin activity in the tissue, growth is disturbed and the plant is lethally damaged.

Physiological effects are the alterations or changes which your body does on its own to maintain a constant inner state called 'Homeostasis' Including your circulation,respiratory rhythm,temperature,biochemicals like pH,pO2,pCO2,etc.

Auxin's characteristics don't exactly fit within a strict hormone definition. Although auxin may act at low concentrations and can be transported, it is not produced in a specific tissue. Auxin may also be too pleiotropic to be considered a hormone.
