Reproduction: How Life ContinuesPractice Questions & MCQs

Q1. Which term is described: 'fusion of male and female gametes'?

• A.Fertilisation
• B.Gamete
• C.Pollination
• D.Meiosis

Answer: A. Fertilisation

What is the textbook's take? Asexual = single parent -> identical offspring (binary fission, budding, fragmentation, spores, vegetative propagation); sexual = two gametes -> zygote with variation; matching the stem's described feature against this list => the option answering the question = Fertilisation. Does that line up with one of the options? Yes - Correct. And the rest? option B) 'Gamete' is incorrect: Gamete: a haploid reproductive cell; option C) 'Pollination' fails since Pollination: transfer of pollen from anther to stigma. Pick: A) Fertilisation.

Q2. Which term is described: 'the cell formed after fertilisation'?

• A.Zygote
• B.Pollination
• C.Meiosis
• D.Germination

Answer: A. Zygote

NCERT fact (biology, chapter 'Reproduction: How Life Continues'): Asexual = single parent -> identical offspring (binary fission, budding, fragmentation, spores, vegetative propagation); sexual = two gametes -> zygote with variation; matching the stem's described feature against this list => the option answering the question = Zygote. Why option A fits - Correct. Distractor analysis: option B) 'Pollination' is wrong because Pollination: transfer of pollen from anther to stigma; option C) 'Meiosis' is wrong because Meiosis: division that forms haploid gametes. Final answer - A) Zygote.

Q3. Which term is described: 'a haploid reproductive cell'?

• A.Gamete
• B.Meiosis
• C.Germination
• D.Stamen

Answer: A. Gamete

Which principle settles this? Asexual = single parent -> identical offspring (binary fission, budding, fragmentation, spores, vegetative propagation); sexual = two gametes -> zygote with variation; matching the stem's described feature against this list => the option answering the question = Gamete. Does that line up with one of the options? Yes - Correct. And the rest? option B) 'Meiosis' is incorrect: Meiosis: division that forms haploid gametes; option C) 'Germination' is wrong because Germination: the sprouting of a seed into a seedling. Pick: A) Gamete.
