Adaptations of organisms (Edexcel Int. A-level Biology)

Topic 4: Plant structure and function, Biodiversity and Conservation (Edexcel Int. A-level Biology)

All 10 lessons included in this bundle are highly detailed and are fully-resourced. The lesson PowerPoints and their accompanying worksheets contain a wide range of tasks that will engage and motivate the students whilst covering the following specification points as set out in topic 4 of the Edexcel International A-level Biology specification: * The structure and ultrastructure of plant cells * The function of the organelles in plant cells * The structure and function of starch and cellulose * The similarities and differences between the structures, position and functions of sclerenchyma, xylem and phloem * The importance of water and inorganic ions in plants * Understand that classification is a means of organising the variety of life based on relationships between organisms * New taxonomic groupings * The meaning of the terms biodiversity and endemism * Know how biodiversity can be measured within a habitat and within a species * Comparing biodiversity between habitats using the index of diversity * The adaptations of organisms to their environment * Use of the Hardy-Weinberg equation * Changes in allele frequency are the result of mutation and natural selection * Evaluate the methods used by zoos and seed banks in the conservation of endangered species and their genetic diversity If you would like to sample the quality of lessons in this bundle then download the cellulose & starch and modern-day classification lessons as these have been uploaded for free
