Vedclass · Answer

(A) In plants, various parts undergo modifications to perform specific functions:$1$. In $Pea$ $(Pisum 	ext{ } sativum)$, the leaves are modified into tendrils to provide support for climbing.$2$. In $Opuntia$, the leaves are reduced to spines to reduce water loss, and the stem becomes fleshy and green to perform photosynthesis.$3$. In $Grapevine$ $(Vitis 	ext{ } vinifera)$, the tendrils are modifications of the stem, not the root.$4$. In $Rhizophora$, the roots are modified into pneumatophores (respiratory roots) to help in respiration in marshy areas, not the stem.Therefore, the correct pair is $Tendril - Pea - Leaf$.
