Study Notes
Seed Dispersal
- Seed dispersal is the movement of seeds from the parent plant to a new location.
- Crucial for plant reproduction as it prevents competition for resources (water, nutrients, air).
Methods of Seed Dispersal
-
Air:
- Seeds are small and light.
- Some have wings (e.g., pine, maple) or hairs (e.g., silk cotton, dandelion) to catch wind.
-
Water:
- Seeds of aquatic or water-adjacent plants are often small, hollow, or buoyant (e.g., lotus).
- Some have fibrous coverings and air pockets (e.g., coconut) facilitating water dispersal.
-
Animals:
- Animals eat fruits containing seeds and carry then away.
- Seeds may be carried outside of digestive systems (e.g., guava, berries).
- Some seeds have hooks or spines that attach to animal fur/feathers or clothing (e.g., cocklebur).
-
Explosion:
- Some fruits burst open when ripe to release seeds. (e.g., pea)
