Question

What is nutation?

Answer 1

Nutation refers to the bending movement of roots, stems, leaves, and other plant organs caused by differences in growth in different body parts. Simple nutation occurs in flat leaves and flower petals, caused by uneven growth on both sides of the surface.

Complete answer:
To answer this answer, first, we need to learn about the different movements of flowers. Plants mainly show two types of movement. Growth-dependent movement is known as the tropic movement and non-growth-dependent movements are known as a nastic movement.

Plants do not move from one position to another, but they also make movements in response to external stimuli. There are different types of movement shown by plants. It may or may not be a movement for growth. Plants mainly show two types of movement. Growth-dependent movement is known as the tropic movement and non-growth-dependent movements are known as nastic movements.
Tendril, a plant organ specializing in anchoring and protecting vine stems in botany. Modified leaves, leaflets, leaf tips, or leaf stipules may be tendrils, but they may be derived from modified stem branches. Some special plant structures serve a similar function, but the tendril is unusual in being a specialized lateral organ with a powerful twining propensity that causes any entity encountered to be surrounded by it.
Nutation refers to the bending motions of the stems, roots, leaves, and other organs of the plant caused by growth variations in the various parts of the organ. Nutational movements are normally distinct from variational movements triggered by temporary changes in water pressure within plant cells.

Note:
Nutation is a spontaneous movement of plants whereas; tropic, tactic, and nastic movements are induced movement of plants.
