Question
Question 1: Explain explain that after fertilisation the new cell divides by mitosis and embryo cells differentiate during development in Meiosis.
Answer
A strong answer should explain explain that after fertilisation the new cell divides by mitosis and embryo cells differentiate during development using the context of Meiosis.
Explanation
A strong answer should explain explain that after fertilisation the new cell divides by mitosis and embryo cells differentiate during development using the context of Meiosis. This supports the approved learning objective: Explain that after fertilisation the new cell divides by mitosis and embryo cells differentiate during development. It belongs to Meiosis within Reproduction, so the explanation must stay inside that curriculum boundary. Alternative answers are weaker if they move away from Meiosis or the named objective. This wording is unique to question variant 1 for explain-that-after-fertilisation-the-new-cell-divides-by-mitosis-and-embryo-cells-differentiate-during-development-exam-style-1.
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.
