Answer 1

Answer:

hey mate here is your answer ❤️❤️❤️❤️❤️

ANSWER:-

• Cross pollination produces better offspring but the yield is not higher because not all pollen grains are able to reach the stigma of other flowers and incompatibility barriers are also there in which pollen of one species is not able to germinate on the stigma of other species. Hence statement A is incorrect.

• Cross pollination occurs in unisexual as well as bisexual flowers. In some plants, bisexual flowers have adaptations that prevent self pollination such as floral barriers, heterostyly, dicliny etc. and only cross pollination can occur in such flowers. Hence, statement B is incorrect.

• Cross pollination can occur over long distances where the pollination is carried out by means of pollinating agents such as wind, water, insects, birds etc. Hence statement C is incorrect.

• Cross pollinated plants need to produce a large number of pollen grains as most of them are lost in their journey from one flower to another flower. Hence, statement D is correct.

So, the correct answer is D.

answer =it requires reproduction of large number of pollen grains..
