Question
- A. It means students should be able to explain that after fertilisation the new cell divides by mitosis and embryo cells differentiate during development.
- B. It means embryo is never assessed in Reproduction.
- C. It means learners only need to memorise the topic title for Meiosis.
- D. It means students should give the opposite of the approved learning objective.
Answer
The correct answer is It means students should be able to explain that after fertilisation the new cell divides by mitosis and embryo cells differentiate during development..
Explanation
The correct option is It means students should be able to explain that after fertilisation the new cell divides by mitosis and embryo cells differentiate during development. because it directly reflects the approved learning objective: Explain that after fertilisation the new cell divides by mitosis and embryo cells differentiate during development..
Common mistake
Misunderstanding the role of mitosis after fertilisation
Students often think that fertilisation itself is a mitotic division, or that the zygote immediately undergoes mitosis to produce a single cell, rather than recognising that fertilisation restores the diploid chromosome number and the resulting zygote then divides by mitosis to form the embryo.
Explain that fertilisation is the fusion of two haploid gametes to create a diploid zygote. The zygote then undergoes a series of mitotic divisions (cleavage) to increase cell number while maintaining the chromosome number, and these cells subsequently differentiate into the various tissues of the developing embryo.
