What are the requirements to grow seeds?

• water

• sunlight(warmth)

• air

• soil

• space

Why do the seeds need to be away from the parent plant?

• Less competition: if seeds grow too close to the parent plant, they compete for water, sunlight, and nutrients.

• New places: moving away allows seeds to grow in new areas.

What are different methods of seed dispersal?

• Wind dispersal: some seeds are lightweight and have special structures, like wings or fluff, that allow them to be carried by the wind. Such as dandelion and maple seeds.

• Water dispersal: seeds from plants that grow near water often float and can be carried away by rivers, streams, or oceans. Such as coconut.

• Animal dispersal: animals play a big role in seed dispersal. Some seeds have hooks or sticky surfaces that attach to animal fur, such as bur. While other seeds are eaten by animals after digestion. Such as berries.

• Explosive dispersal: some plants have seed pods that burst open when they are dry, scattering seeds in all directions. Such as pea.
