Question

Which of the following situations correctly describes 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 motile transported.
(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)

Answer 1

The correct option is B (iv) only

Human egg	Angiospermic egg
Humans are reproductively active throughout their reproductive phase. So, the eggs don't form only once in their lifetime, it produces many times.	Angiosperms are also reproductive throughout their reproductive phase. So, egg produces much time during their reproductive phase.
Human eggs are not stationary. During the process of ovulation, eggs are released from the ovary and transported to the uterus through the fallopian tube.	Angiospermic eggs are stationary. Eggs remain closely packed in the ovary.
Human eggs are not actively motile like human sperm.	Angiospermic eggs are non-motile. That's why for the process of fertilization male gamete enter inside the ovary through the stigma and style.
Syngamy (zygote) formation takes place during the fertilization process.	Syngamy (zygote) formation takes place during the fertilization process.

So, the correct answer is ' Syngamy in both results in the formation of zygote '.
