NEET BIOLOGY

Detailed explanation-1: -Some plants like the pea plant climb up other plants or fences by means of tendrils. These tendrils are sensitive to touch. 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.

Detailed explanation-2: –The stem of a pea plant is very weak. As it can not stand by its own, it climbs with the help of another plant or wall and sticks with them.

Detailed explanation-3: -Peas need a trellis for climbing. Peas are adapted to climb with beautiful little tendrils. They’re modified leaflets and one of the things I love most about peas! While some plants like trees have woody tissues to hold them up, other plants climb on other structures (and woody plants) to get vertical.

Detailed explanation-4: -The growth in the tendrils of pea plants occurs when cell division takes place in the tendrillar cells that are away from the support. It causes the tendrils to bend toward the support and curl around it.

Detailed explanation-5: -To support the weak and thin stems, the terminal leaves are modified into thin, wiry, coiled structure called tendrils. Tendrils coil around the nearby objects and support the plant to climb up.
