In the alternation of generations in a fern, which statement is correct?

hard MCQ 5 marks Class 10 · Science · How do Organisms Reproduce
  1. The sporophyte generation is diploid and produces spores by meiosis.
  2. The gametophyte generation is diploid and bears spores.
  3. Both sporophyte and gametophyte are haploid.
  4. The sporophyte produces gametes directly.
Answer
The sporophyte generation is diploid and produces spores by meiosis.

The correct answer is The sporophyte generation is diploid and produces spores by meiosis. — Thus the correct answer is: The sporophyte generation is diploid and produces spores by meiosis.

Step-by-step solution

  1. Recall that in alternation of generations the sporophyte is the diploid phase and reproduces by producing spores through meiosis.
  2. Read each option and compare with this definition.
  3. Option A states that the sporophyte is diploid and produces spores by meiosis, which matches the concept.
  4. Options B, C and D contain incorrect information about ploidy or reproductive products.
  5. Select the option that correctly describes the sporophyte.
  6. Thus the correct answer is: The sporophyte generation is diploid and produces spores by meiosis.
Common mistake: Confusing which generation is diploid and which produces spores

Concept tested: Alternation of generations
