Question

Some plants like the pea plant climb up other plants or fences bynmeans of tendrils When they come in the contact with support,thenplant of the tendril in the object does not grow as rapidly as thenpart of tendril away from the object Explain

Answer 1

When the tendril comes in contact with the object the phytoharmone auxin diffuses to the other side of the plant which does not touch the object . Hence the part of plant which has auxin grows which appears like swirling around the object.

Hope this helps.

Answer 2

This is because of the different amount of auxins secretion in both parts.

Explanation:

When tendrils come in the contact with a support, the auxins ( a phytohormone ) that help in the plant growth, starts moving away from the part that is in contact with support toward the end that is away from support.

Due to less concentration of auxins the former part experiences less growth whereas the latter one undergoes more growth.
