Question

Which among the following is an incorrect statement?

(a) Zygote is formed by fusion of male and female gametes and is diploid in nature

(b) Zygote undergoes reduction division to form a structure called sporophyte

(c) Sporophyte undergoes meiosis to produce spores

(d) Spores germinate to form new thallus

This question was posed to me in an interview.

This intriguing question comes from Plant Kingdom in section Plant Kingdom of Biology – Class 11

Answer 1

Correct option is (b) Zygote undergoes reduction division to form a structure called sporophyte

To explain I would say: Zygote is formed by fusion of male and female gametes and is diploid in nature. Zygote doesn’t undergo reduction division immediately after fusion. They instead form a structure called as sporophyte. Sporophyte undergoes meiosis to produce spores. Spores germinate to form new thallus.
