Question

Winged pollen grains are present in

• A. Mustard
• B. Mango
• C. Cycas
• D. Pinus

Answer 1

The Correct Option is D

To determine which plant has winged pollen grains among the given options, let's examine each one closely in the context of their botanical characteristics.

1. Mustard: Mustard plants belong to the family Brassicaceae, which typically exhibit small, spherical pollen grains that are not winged. These pollen grains are transported by insects primarily.
2. Mango: The mango plant (Mangifera indica) has pollen grains that are typically ovoid or spherical and are transported by insects. They are not winged either.
3. Cycas: This is a genus of seed plants where pollen grains are generally not winged. Cycads have wind-pollination but their pollen grains are usually round and not specifically adapted with wings.
4. Pinus: Pinus belongs to the conifer group, which includes species whose pollen grains are characteristically winged to aid in wind dispersal. Winged pollen helps in floating and traveling longer distances in the air.

Based on the characteristics discussed, the correct answer is Pinus because it is a gymnosperm, which commonly has winged pollen grains that facilitate wind pollination over long distances. The wings on the pollen grains increase buoyancy, allowing them to travel through the air more effectively.

In conclusion, the presence of winged pollen grains is a distinguishing feature of Pinus among the given options.
