Answer Key / Explanation : (a) -

(a)

Leaf tendrils Modified thread/spring-like sensitive structures of leaf or leaf parts, e.g., in sweet pea (Lathyrus odortus).

Leaflet hooks In unguis-cati (cat’s nail), the terminal leaflet are modified into cured hooks (as of cat) for climbing.

Pitcher Lamina in Nepenthes is modified into pitcher, which functions in catching and digesting microorganisms or storing water.

Bladder In Utricularia (an aquatic insectivore), a few leaf segments are modified into bladder (balloon-like structures) for trapping small aquatic organisms.
