An auxin is a class of plant growth substance which plays an essential role in coordination of many growth and behavioural processes in the life cycle of a plant.
Auxin hormone
Phototropism is the biological process for auxin's.
Auxin is a hormone that is found solely in plants.
auxin
Auxin is the chemical that promotes phototropism in plants. Auxin is produced at the tips of plant stems and helps cells elongate, causing the plant to bend towards a light source.
Auxin is a plant hormone that is involved in many signal processes. It is most commonly talked about in apical dominance
auxin plays an important role in the growth of meristemetic tissue so as to increase the height of plant.
The chemical name for auxin is indole-3-acetic acid (IAA).
The effect of auxin on root growth is called root initiation or root elongation. Auxin promotes cell division and cell elongation in the root, leading to increased root growth.
yes
b auxin increases the quantity of cytoplasm in a cell ps... are you in my class?
No, the auxin produced on the side facing the light source simply moves to the side away from the light. This causes cell elongation on the side opposite the light, making the stem appear to "grow toward the light"
