Answer 1

The correct option is B

Insects Or Wind

The correct option is B:

Explanation of the correct option:

1. Pollination by various agencies is highly dependent on the pollen grains and blooms generated by the plant.
2. The pollen grains generated by water hyacinth are small and light, but the pollen grains produced by water lily are big and sticky.
3. Insect pollination occurs in plants that produce vividly coloured blooms with a pleasant odour, as well as pollen grains that are bigger, sticky, and spiny.
4. Water lily and sunflower are examples of insect-pollinated plants.
5. Wind pollination occurs in plants that produce light-coloured blooms with no nice odour and pollen grains that are smaller and lighter in weight.
6. Water hyacinth, grasses, and cereal crops are among the plants pollinated by the wind.

Explanation of the incorrect option:

Option A:

1. Water hyacinth and water lily flowers are not buried in the water and do not discharge pollen grains into the water, hence they are not pollinated by water.
2. Eelgrass, common waterweed, is a water pollinated plant.

Option C:

1. Water hyacinth and water lily flowers are not buried in the water and do not discharge pollen grains into the water, hence they are not pollinated by water.
2. Eelgrass, common waterweed, is a water pollinated plant.

Option D:

1. Water hyacinth and water lily flowers are not buried in the water and do not discharge pollen grains into the water, hence they are not pollinated by water.
2. Eelgrass, common waterweed, is a water pollinated plant.

Final answer: In water hyacinth and water lily pollination takes place by insects and wind respectively.
