On what basis are the folding of Mimosa leaves and the coiling of tendrils around support different?
Answer and explanation
Correct answer: Mimosa movement is rapid and based on changes in water pressure, while tendril movement is growth based
Mimosa leaf folding is a rapid, non-growth movement caused by changes in turgor or water pressure in specialized cells after touch. A tendril coils around support more slowly because contact causes unequal growth on its two sides; this is a growth movement. Both responses involve a stimulus, but their mechanisms and speed differ. Thus A is correct, while B, C and D incorrectly apply animal processes or deny stimulation.
