9.4.U1 Flowering involves a change in gene expression in the shoot apex.
9.4.U2 The switch to flowering is a response to the length of light and dark periods in many plants.
9.4.U3 Success in plant reproduction depends on pollination, fertilization and seed dispersal. [Students should understand the differences between pollination, fertilization and seed dispersal but are not required to know the details of each process.]
9.4.U4 Most flowering plants use mutualistic relationships with pollinators in sexual reproduction.
9.4.A1 Methods used to induce short-day plants to flower out of season. [Flowering in so-called short-day plants such as chrysanthemums, is stimulated by long nights rather than short days.]
9.4.S1 Drawing internal structure of seeds.
9.4.S2 Drawing of half-views of animal-pollinated flowers.
9.4.S3 Design of experiments to test hypotheses about factors affecting germination.
