HL Biology Summer work: Prior knowledge review of plant biologyTask: produce a knowledge bank (KB) containing what you have previously learned about plant biology. You may choose the precise structure of this KB, as long as the information is concise and well-organised, and you use diagrams. You must be able to find specific information quickly. For example, you may wish to create a placemat to chunk information into sections, or produce Q&A flashcards.Reviewing GCSE knowledge – plant transport and growthTo access the GCSE textbook please use: User: RGSstudent, Password: student1Page references are given for each questionDescribe stomata and explain why they are needed by a plant. Consider the processes of respiration and photosynthesis. [p61, 57]Define ‘transpiration’, using ideas of evaporation and diffusion [p70].Describe the route of water, through the plant, to replace water that is lost from the leaves through transpiration [p70].Explain how water is taken up from the soil, into the plant roots [p109, 88-89].Explain the effects of the following abiotic factors on the rate of transpiration: (a) temperature, using ideas of kinetic energy and evaporation, and (b) humidity, using ideas of water vapour gradient [p74].Describe at least three adaptations of plants in deserts [p75, 71]. Compare and contrast the structure and function of xylem and phloem vessels [p72, 76-77].Label diagrams of the stem, root and leaves, to show the location of xylem and phloem vessels [p73].Define ‘meristem’, including the importance of this tissue in plants [p222].Explain how the plant hormone auxin controls phototropism in shoot tips [p220-221].Describe how plant are grown from small groups of cells, when plants are cloned by tissue culture [p308].Reviewing KS3 knowledge – plant reproductionPlease use BBC bitesize KS3 website to help you find this information, but clicking through the section about plant reproduction. a diagram of a half-view of an animal pollinated flower, including anther, filament, ovary, ovule, petal, sepal, stamen, stigma, and style.Define the following terminology:PollinationFertilisationSeed dispersalExtension: Flowering plants often have mutualistic relationships with insects. Describe this type of relationship and explain how it applies to flowering plants and insects. ................
