How do auxin promote the growth of tendrill around a support
Answers
•Some plants like pea plant climb up other plants or fences by means of tendrils.
• These tendrils are sensitive to touch and when they come in contact with any support, the part of the tendril in contact with the object does not grow as rapidly as the part of the tendril away from the object.
• This causes the tendril to circle around the object and thus cling to it.
• this type of movement is also called Thigmotropic movement because the plant parts move in response to the stimulus of touch and these are growth moments.
HEY FRIEND HERE IS UR ANSWER ,
Auxins are the plant hormones produces at the tip of a shoot and root. Auxins are present at the tip of tendrils. When tendrils are attached around any support their growth is slowed down as auxins are sensitive to touch. This make them move to the other side of the tip to get support this makes the other side grow faster than the side of tendril in contact with the support and the tendril bends towards the support.
