Answer: (B) (2) Entomophily. Answer: B.
- A.(1) Anemophily
- B.(2) Entomophily✓
- C.(3) Hydrophily
- D.(4) Cleistogamy
Correct Answer
(B) (2) Entomophily
Solution & Explanation
Answer: B. Attractants (colour, fragrance) and rewards (nectar and pollen) are needed to sustain visits by animal pollinators — i.e. entomophily (insect pollination). Anemophily (wind) and hydrophily (water) are abiotic and do not offer rewards; cleistogamy is self-pollination in closed flowers needing no agent. NCERT: Ch 1, p.14, lines 32-35 — "the flowers have to provide rewards to the animals. Nectar and pollen grains are the usual floral rewards"
