Question

Choose the correct statements among the following:
1. Duplication of genome, synthesis of other cell constituents, and division to produce new cells is called cell cycle.
2. Interphase is followed by a resting phase.
3. In every cell division, genetic variability will increase from generation to generation.
4. Plant cells can divide mitotically in both haploid and diploid cells.
Identify the correct option from the following:

• A. I, II
• B. III, IV
• C. I, IV
• D. II, IV

Hint:

Always cross-check definitions and biological processes like the cell cycle and cell division types while solving such questions — small differences in terminology often make or break the correctness.

Answer 1

The Correct Option is C

Statement I: Correct — The cell cycle includes genome duplication, synthesis of other materials, and division. Statement II: Incorrect — Interphase is a phase of intense activity preparing for division, not a resting phase. Statement III: Incorrect — Genetic variability increases during meiosis (due to crossing over and recombination), not in every cell division. Statement IV: Correct — Plant cells can undergo mitotic division in both haploid (e.g., gametophytes) and diploid (e.g., sporophytes) conditions.
