why the photo above is called the embarrassed daughter plant?
because when touched the leaves will close.
The uniqueness of this plant is when its leaves are touched, blown, or heated it will immediately "close". This is caused by changes in turgor pressure on the leaf bone. Stimulation can also be felt other leaves that do not come untouched. This motion is called seismonasti, which is influenced by touch stimulation (tigmonasti), which is like a tigmonasti movement of the shy princess leaves that does not care where the direction of touch comes from. Embry daughter plant closes its leaves to protect itself from plant-eating animals (herbivores) who want to eat it. The color of the lower leaves of the embarrassed daughter's leaves is pale, showing a pale color, the animal that had wanted to eat this plant would think that the plant had withered and became no longer interested in eating it. This plant also buds at sunset and rupture once the sun rises.
