Question

Explain how pollination is possible between two flowers borne on two different apple trees in a garden. Name any two agents that would be able to pollinate such flowers.

Answer 1

Pollination between two flowers on two different apple trees in a garden takes place by cross-pollination.

Cross-pollination:

1. It is the process of transfer of pollen grains from the anther to the stigma of the two different flowers.
2. There are two different flowers from two different trees in which cross-pollination occurs.
3. The offsprings are non-identical to the parent.

The two agents that can pollinate such flowers are wind and insects.

Wind pollination:

1. The pollination or transfer of pollen is carried out by wind currents. It is called anemophily.

Insect pollination:

1. The pollination or transfer of the pollen grains is carried out by the insects. It is called entemophily.
