photohomerone
Greater concentration of auxin in the cells facing light restrict cell elongation whereas on the other side (away from light) more elongation of cells takes place due to optimum amount of auxin. thus, the shoots turn towards light.
plant growth controlled by hormone called auxin which is found in roots and shoots and sunlight break down auxin answered by rasool ebrahimi
slow cell growth

Auxin controls the growth of the plant. Auxin in the roots of the plant inhibits growth whereas in the stems in the stems it encourages growth.
slow cell growth
true
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"
the shoots pull towards the sunlight and against gravity - the roots pull towards gravity and water
slows cell growth
the stimulus in this case is gravity .shoots grow up,away from gravity.roots grow down,towards gravity.again auxin control this growth.if a plant is put its side the auxin builds up on the lower side of the shoot and the root.in the shoot the auxin stimulates it to grow moreon the lower sidethis causes the shoot to bend upwardsin the root the auxin also builds up on the lower side.but Ayxin slows down growth in a rootso tht upper side of the root grows quicker than the lower sidethe root bends downwards
auxin
Auxin were the first plant hormones discovered. Charles Darwin was one of the first pioneers and wrote a book called The Power of Movement in Plants - 1880
