Explain the directional movement due to growth in response to touch in a pea plant.
Marking-scheme solution
Pea plant develops tendrils which help it to climb up other plants or fences or some other support. When they come in contact with any support, the part of the tendril in contact with the support does not grow as rapidly as part of the tendril away from the support. This causes the tendril to circle around the support and thus cling to it.
