Text Solution

Verified by Experts

The correct Answer is:
B

In case of many terrestrial organisms (including both anigiosperms and humans) which exhibit internal fertilisation, syngamy occurs inside the body of the organism to form zygote.
Both the angiosperm and human remains reproductivity active throughout their reproductive phase. It means the formation of egg takes place not only once but many times in a lifetime.
In humans, once an egg has been released from ovary, the beating of cilia in the Fallopian tube moves the egg from the ovary to the uterus. So, the egg is considered as motile not stationary.
In flowering plants (angiosperms), the gametes are non-motile cells within gametophytes, but for the fusion to take place the non-motile male gametes are carried to female gamete by pollen-tubes.
