Explain that the random fusion of gametes at fertilisation produces genetically different individuals
1 Answer Explain that crossing over and random orientation (independent assortment) of pairs of homologous chromosomes and sister chromatids during meiosis produces genetically different gametes
1 Answer Interpret photomicrographs and diagrams of cells in different stages of meiosis and identify the main stages of meiosis
1 Answer Describe the behaviour of chromosomes in plant and animal cells during meiosis and the associated behaviour of the nuclear envelope, the cell surface membrane and the spindle (names of the main stages of meiosis, but not the sub-divisions of prophase I, are expected: prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II and telophase II)
1 Answer Explain the need for a reduction division during meiosis in the production of gametes
1 Answer Explain what is meant by homologous pairs of chromosomes
1 Answer Explain the meanings of the terms haploid (n) and diploid (2n)
1 Answer Describe the role of gibberellin in the germination of barley
1 Answer Explain the role of auxin in elongation growth by stimulating proton pumping to acidify cell walls
1 Answer Describe the rapid response of the Venus fly trap to stimulation of hairs on the lobes of modified leaves and explain how the closure of the trap is achieved
