Answer 1

Answer:

D. Legumes have a swollen leaf base called Pulvinus

Lamina contains veins and veinlets that transmit water to different regions of the leaf. Petiole is flexible thin structure that helps in fluttering of leaves in the air. Based on the presence or absence of petiole, plants are classified into petiolate and sessile respectively. Since petiole is absent in grass, it is considered to be sessile. Legumes have a swollen leaf base called Pulvinus.
