Which of the following situations correctly describe the similarity between an angiosperm egg and a human egg?
i. Eggs of both are formed only once in a lifetime
ii. Both the angiosperm egg and human egg are stationary
iii. Both the angiosperm egg and human egg are mobile
iv. Syngamy in both results in the formation of zygote
Choose the correct answer from the options given below:
A. ii and iv
B. iv only
C. iii and iv
D. i and iv
I. Both angiosperm and humans remain active during their reproductive phase. So, eggs of both are formed many times during their lifetime not just once.
II. Human eggs are not stationery. Once the egg is released from the ovary. It reaches the uterus.
III. In angiosperms both the gametes are non-motile in nature.
IV. The egg after releasing from the ovary reaches the uterus which shows that the human egg and the angiosperm egg both undergoes syngamy of the male and female gamete to form an embryo.
Hence, only statement iv stands true.
