1.	Give an example and explain how plants may immediately respond to a stimulus.
Answer» 1. The plant responding to stimulus is mimosa pudica is the example. 2. Mimosa pudica leaves have pad like sweelings at the base are called PULVINI. 3. Here cells contain water and large intercellular spaces. Due to water pressure pulvini hold the leaf errect. 4. When we touch the leaves, an electrical impulse is generated due to plant hormone. 5. Because of this hormone water in the pulvini cells which are closer to the leaf vein migrate to other side’of the cells. 6. Then pulvini loss its fitness hence leaves become fold. After 20 to 30 minutes water comes back leaves become errect.
