There may be swollen regions at either end of the petiole known as pulvina (singular=pulvinus) that are composed of a flexible tissue that allows leaf movement. Pulvina are common in the bean family Fabaceae and the prayer plant family Marantaceae. A pulvinus on a petiolule is called a pulvinulus.

Answer 2

Answer:

The swollen part at the base of the petiole is called pulvinus

Explanation:

• Pulvinus is the bloated part present at the base of a leaf's petiole.
• The presence of pulvinus can be easily in the leaves of members from leguminosae, anacardiaceae and many more.
• Such leaf bases with pulvinus is called pulvinate leaf bases.
• These pulvinus helps leaves to carry out seismonastic movements (i.e. movements occurring in response to a physical stimulus) as seen in Mimosa pudica and also, helps some plants to carry out nyctinastic movements (i.e. movements occurring in response to darkness) as seen in Arachis hypogea.
