Question

Leaf movement in Mimosa helps to protect it from herbivores and insects.
A. Reduce photosynthesis and protect from grazers
B. Protect from high wind
C. Releasing phytohormones
D. Regulate its growth

Answer 1

Hint: The leaves of the Mimosa exhibit this rapid folding by altering the turgor pressure. Turgor pressure is defined as the amount of water pressure in the cell that is pushing against the cell wall. The Mimosa exhibits this same movement during the night and when it is exposed to abiotic factors like excessive rain and heat, in order to protect the plant from physical damage or desiccation.

Complete answer:
Leaf movement in Mimosa helps to protect it from herbivores and insects. The Mimosa pudica, commonly known as the sensitive plant, exhibits one of the many wonders of nature. When it is touched by another organism, its leaves fold in and its stems become thin. This rapid folding deters herbivores, grazers and insects from eating the Mimosa plant as the plant appears smaller, duller when folded. At the same time it exposes the sharp spines on the plant stems.

Hence the correct answer to this question is option A. Reduce photosynthesis and protect from grazers.
