उत्तर
closing up of leaves of a sensitive plant on touching with an object
Explanation:
The closing of leaves in the sensitive plant (Mimosa pudica) is a thigmonastic movement caused by changes in turgor pressure, not by growth. Therefore, it is not a growth movement. The other options are tropic (growth) movements.
