• B. 2 and 3
• C. 1, 3 and 4
• D. 3 and 4

Answer 1

The correct option is A 1 and 2

Several organisms belonging to fungi, algae and bryophytes have haploid bodies.

The number of male gametes produced is several thousand times more than the number of female gametes produced and not vice versa. This is because a large number of male gametes fail to reach the female gamete during sexual reproduction.

In plants like algae, bryophytes and pteridophytes, gametes are transferred through water.

In a majority of organisms, male gamete is motile and the female gamete is stationary. However, in some fungi and algae, both male and female gametes are motile.
