Question

What are the disadvantages of cross-pollination?

Answer 1

The disadvantages of cross pollination are _

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

(3) The process is uneconomical for the plants because the flowers have to be large, coloured, scented and have produced nectar ----- for attracting pollinating agents.
