Essential Idea:
Reproduction in flowering plants is influenced
by the biotic and abiotic environment
Understandings:
- Flowering involves a change in gene expression in the shoot apex
- The switch to flowering is a response to the length of light and dark periods in many plants
- Success in plant reproduction depends on pollination, fertilization and seed dispersal
- Most flowering plants use mutualistic relationships with pollinators in sexual reproduction
Applications:
- Methods used to induce short-day plants to flower out of season
Skill:
- Drawing internal structure of seeds
- Drawing of half-views of animal-pollinated flowers
- Design of experiments to test hypotheses about factors affecting germination
