Question
Chapter 24, Problem 1MCQ
Summary Introduction

Introduction:

Flowering plants are capable of reproducing by both asexual and sexual mode of reproduction. The asexual mode of reproduction constitutes only mitotic divisions, and in a sexual reproduction, mitosis is followed by meiosis.

Answer to Problem 1MCQ

Correct answer:

Although gametes are produced via mitosis in plants, genetic variation is primarily the result of meiosis. Therefore, option (a) is correct.

Explanation of Solution

Reason for the correct statement:

The diploid cells in plants undergo meiosis in order to produce haploid microspores and megaspores in which, genetic variation takes place as a result of crossing over. These cells then develop into the gametophytes, which produce egg cells and sperm by mitosis.

Option (a) is given as "mitosis; meiosis".

As, “The process of mitosis results in the formation of gametes, sperm and egg cells in the plants, and the process of meiosis leads to genetic variation in the plants”, is the right answer.

Hence, option (a) is correct.

Reasons for the incorrect statements:

Option (b), is given as “meiosis; grafting”.

Grafting is the artificial and asexual method of plant growth in which no gamete formation takes place. Hence, it is a wrong answer.

Option (c), is given as “budding; mitosis”.

Budding is an asexual mode of reproduction in which, no gamete formation takes place, and mitosis does not allow genetic variation. Hence, it is a wrong answer.

Option (d), is given as “binary fission, asexual reproduction”.

Binary fission is an asexual mode of reproduction, and asexual reproduction does not allow gamete formation and genetic variation. Hence, it is a wrong answer.

Hence, the options (b), (c), and (d) are incorrect options.

Conclusion

Gametes are produced via mitosis in plants, and genetic variation is primarily the result of meiosis in plants.
