Cell Growth and Cell DivisionQuiz - Solve & Score
Q1. Meiosis produces how many cells?
- A.4
- B.2
- C.1
- D.8
Answer: A. 4
The idea this question leans on: Meiosis => 4 haploid cells. That fits the listed correct option directly - Correct. Looking at the others: option B) '2' misses the point - That is mitosis; option C) '1' misses the point - Four cells form. Hence the answer is A) 4.
Q2. Which process/term is described: 'produces two identical diploid daughter cells'?
- A.Mitosis
- B.Cytokinesis
- C.Karyokinesis
- D.Chromosome
Answer: A. Mitosis
NCERT fact (biology, chapter 'Cell: The Building Block of Life'): Identify the defining feature of the structure/tissue named in the question; match that feature against the four options => only one option is consistent with the textbook description; therefore the correct identification = Mitosis. Why option A fits - Correct. Distractor analysis: option B) 'Cytokinesis' doesn't hold - Cytokinesis: division of the cytoplasm after the nucleus; option C) 'Karyokinesis' fails since Karyokinesis: division of the nucleus. Final answer - A) Mitosis.
Q3. Which process/term is described: 'produces four haploid cells (gametes)'?
- A.Meiosis
- B.Karyokinesis
- C.Chromosome
- D.Interphase
Answer: A. Meiosis
NCERT fact (biology, chapter 'Cell: The Building Block of Life'): 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 = Meiosis. Why option A fits - Correct. Distractor analysis: option B) 'Karyokinesis' is wrong because Karyokinesis: division of the nucleus; option C) 'Chromosome' misses the point - Chromosome: thread-like DNA-bearing structure. Final answer - A) Meiosis.
