Learning objective Time taken Learning Outcome Learning activity with opportunity to develop skills Assessment opportunities Resources Required practical 2: Preparation of stained squashes of from plant root tips; set-up and use of an optical microscope to identify the stages of mitosis in these stained squashes and calculation of a mitotic index. Measurement of cells and calculation of their actual size. 0.6 weeks knowledge of mitosis and the cell cycle, to identify cells in different stages of mitosis. Use measured values to calculate the actual size of cells. Explain what the mitotic index is and calculate the mitotic index from observed values. Learning activities: preparation and observation of squashes of root tip cells eg from allium, garlic or hyacinth observation and drawing of cells in various stages of mitosis, under a microscope calculation of actual size of cells and the mitotic index exam questions. Skills developed by learning activities: AO1 – knowledge and understanding the techniques and procedures for staining chromosomes and using microscopes AO2 – application of knowledge to use these techniques and identify stages of mitosis in tissue being observed AT d and e – students prepare, observe and draw Past exam paper material: Students could undertake the HBI3T ISA P from 2013 Specimen assessment material: AS Paper 2 (set 1) – Q1 Exampro: BYA2 Jan 05 Q1 BYA2 Jun 05 Q4
