Solution
Each point: 1 Mark
Seed dispersal occurs by the following agents:
1. Dispersal by wind - The seeds that are dispersed by wind are usually light in weight and have wing-like structures for efficient propagation. The stigma of these flowers have hair like structures. eg: maple.
2. Dispersal by water - This kind of dispersal occurs in aquatic plants and plants which grow near water bodies. eg: coconut seeds.
3. Dispersal by animals - Some seeds have spine-like structures on them. They get stuck on the fur of the animals and get spread to different places.
