a) The five different types of Habitat are: 1. Forest 2. Desert 3. Grassland 4. Aquatic (e.g., Ocean, Freshwater) 5. Mountain b) Sexual propagation is a method of plant reproduction that involves the fusion of male and female gametes, typically resulting in the formation of a seed. This process leads to offspring that are genetically diverse from the parent plants. c) The difference between epigeal and hypogeal germination lies in the position of the cotyledons relative to the soil surface: • In epigeal germination, the hypocotyl elongates rapidly, pushing the cotyledons and plumule above the soil surface. Examples include beans and castor. • In hypogeal germination, the epicotyl elongates, while the cotyledons remain below the soil surface. Examples include maize and peas.
