| List-I | List-II |
| A. Wind pollination | I. Bees |
| B. Water pollination | II. Grasses |
| C. Dominant biotic pollinating agents | III. Zostera |
| D. Tallest flower | IV. Amorphophallus |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-II, B-III, C-I, D-IV
Pollination needs an agent that carries pollen from the anther to the stigma. The agent may be abiotic (wind or water) or biotic (animals). Each pair below links an agent or a flower to its NCERT example.
(A) Wind pollination — this matches (II) Grasses. Grasses make light, non-sticky pollen in large amounts and have well-exposed stamens, so the wind carries their pollen easily.
(B) Water pollination — this matches (III) Zostera. Water pollination is rare. Zostera is a marine sea-grass, and Vallisneria and Hydrilla are the fresh-water examples.
(C) Dominant biotic pollinating agents — this matches (I) Bees. Many animals pollinate flowers, but among them insects, and bees in particular, do most of the work.
(D) Tallest flower — this matches (IV) Amorphophallus. Its flower is about 6 feet tall. It offers insects a safe place to lay eggs as its floral reward.
NCERT Extract:
Pollination – “… Wind-pollination is quite common in grasses. Pollination by water is quite rare in flowering plants and is limited to about 30 genera, mostly monocotyledons. … Some examples of water pollinated plants are Vallisneria and Hydrilla which grow in fresh water and several marine sea-grasses such as Zostera. … Among the animals, insects, particularly bees are the dominant biotic pollinating agents. … In some species floral rewards are in providing safe places to lay eggs; an example is that of the tallest flower of Amorphophallus (the flower itself is about 6 feet in height).”
