What is a plantlet? Define the stimulus.

Plantlets are very small or young plants or undeveloped plant. New plants are grown from the plantlets. These plantlets are capable of growing into a mature adult plant once they are provided with a suitable substratum.

A stimulus is any change in an organism's physical or chemical environment (including internal or external environment). Sensitivity is the ability of an organism or a particular organ to detect external change or stimuli to give an appropriate reaction.
