Concept: This question tests your knowledge of plant morphology, specifically the modifications of stipules for support.
Why (B) is correct: In Smilax, the stipules are modified into tendrils. These tendrils help the weak stem of Smilax to climb and provide support.
Why other options are wrong:
- (A) Gloriosa: In Gloriosa, the leaf apex is modified into a tendril.
- (C) Pisum sativum: In Pisum sativum (pea plant), the leaflets are modified into tendrils.
- (D) Lathyrus aphaca: In Lathyrus aphaca (wild pea), the entire leaf is modified into a tendril, and the stipules become leaf-like (foliaceous) to perform photosynthesis.
Common Mistake: Students often confuse which part of the leaf (leaf apex, leaflet, entire leaf, or stipule) is modified into a tendril in different plants.
NEET Tip / Mnemonic: Remember "Stipules in Smilax" for stipular tendrils. For others, associate the plant with the specific leaf part: Gloriosa - Great Leaf apex; Pisum - Peaflets (leaflets); Lathyrus - Leaf tendril.
Correct Answer: (B)
Smilax
