Question

Which among the following statements are true for sexual reproduction in flowering plants?

(i) It requires two types of gametes.

(ii) Fertilisation is a compulsory event.

(iii) It always results in the formation of zygotes.

(iv) Offspring formed are clones.

• A. (i) and (iv)
• B. (i), (ii), and (iv)
• C. (i), (ii), and (iii)
• D. (ii), (iii), and (iv)

Answer 1

The correct option is C

(i), (ii), and (iii)

The correct option is C.

Explanation of the correct option:

Statement (i):

Sexual reproduction is a process that involves two parents and produces two types of gametes, male and female.

Statement (ii):

1. Fertilization is the union of haploid male gametes, sperm, and haploid female gametes, ovum.
2. During fertilization, the gametes combine to form the zygote. This necessary occurrence ensures the survival of the species.

Statement (iii):

1. Fertilization is the union of haploid male gametes, sperm, and haploid female gametes, ovum.
2. The product of fertilization is a zygote.

Explanation of the incorrect options:

Statement (iv):

Clones are offspring produced through asexual reproduction. However, genetic recombination and variation in the progeny can be seen in sexual reproduction.

Final answer: Statements (i), (ii), and (iii) are true.
