Variation and evolution
Question
- A. Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Cloning (biology only) because students must describe tissue culture as using small groups of plant cells to grow identical new plants.
- B. Scale confusion: Claiming mitosis produces gametes. This would blur Mitosis vs meiosis instead of testing Cloning (biology only).
- C. Process confusion: Forgetting chromosome number is maintained in mitosis but halved in meiosis. This misses the objective focus on describe tissue culture as using small groups of plant cells to grow identical new plants.
- D. Evidence confusion: It moves into a neighbouring Unit 4.6 idea rather than Variation and evolution / Cloning (biology only).
Answer
The correct option is Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Cloning (biology only) because students must describe tissue culture as using small groups of plant cells to grow identical new plants.. It is the only option that keeps Mitosis vs meiosis separate and answers the approved learning objective in Cloning (biology only).
Explanation
The correct option is Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Cloning (biology only) because students must describe tissue culture as using small groups of plant cells to grow identical new plants.. Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Cloning (biology only) because students must describe tissue culture as using small groups of plant cells to grow identical new plants. is correct because Mitosis produces identical cells; meiosis produces genetically different gametes. The learning objective says students must describe tissue culture as using small groups of plant cells to grow identical new plants, so the answer must stay inside Cloning (biology only). The alternative options are wrong because they either claiming mitosis produces gametes., forgetting chromosome number is maintained in mitosis but halved in meiosis., or drift away from meiosis questions must focus on gametes, halved chromosome number, sexual reproduction, or variation..
Common mistake
Cloning (biology only) common mistake 1
Giving a vague answer instead of directly addressing: Describe tissue culture as using small groups of plant cells to grow identical new plants..
Answer by clearly explaining how to describe tissue culture as using small groups of plant cells to grow identical new plants..
