Question

Describe the advantages and disadvantages of cross pollination to the plants

Answer 1

Advantages of cross pollination:

The offspring are healthier.

The seeds are produced in larger number and are more viable.

The seeds develop and germinate properly and grow into better plants.

Results in new varieties because cross-pollination can be carried out between two different varieties of the same species or even two species.

Disadvantages of cross pollination:

It is not always certain as a pollinating agent is always required, and it may or may not be available at the suitable time.

Pollen grains have to be produced in abundance to ensure chances of pollination. This results in lot of wastage of pollen.

It is uneconomical for plants as they have to produce flowers that are large, perfumed and with nectar to attract insects.

Answer 2

Answer:

Advantages of cross-pollination-

1. The offsprings are healthier.

2. The seeds produced are abundant and viable.

3. New varieties may be produced by cross pollinating two different varieties of the same

species or even two distinct species.

Disadvantages of cross-pollination

1. The pollination is not always certain because some pollinating agent is always needed which may or may not be available at the proper time.

2. The pollen has to be produced in large quantity to ensure maximum chances of pollination which means a lot of wastage of pollen.

3. The process is uneconomical for the plant because the flowers have to be large, coloured, scented and have to produce nectar-for attracting pollinating agents.
