Question

Zygospore is formed from

• A. Gametangial copulation
• B. Gametic union
• C. Zygote
• D. Oogamy

Answer 1

Answer: (A)

Gametangia are the sex organs of fungi. The male and female gametangia are born on two different fungal hyphae. The two gametangia from different sex unite together and form a fertilization tube through which the male gamete migrates into the female gametangium. This process of fusion of gametes in fungi is known as Gametangial copulation.

When the two gametes of opposite sex come together it is known as a gametic union. A zygote is formed by the fusion of male and female gametes.

Oogamy is a form of sexual reproduction. It is a form of anisogamy (heterogamy) in which the female gamete (e.g. egg cell) is significantly larger than the male gamete and is non-motile.

So, the correct answer is option A.
