What are the 4 types of seeds and how are they spread?

The four types of seeds are:

1. Drupe seeds (e.g., cherries) that are often spread by animals who eat the fruit and excrete the seeds.
2. Nut seeds (e.g., acorns) that are typically dispersed by animals that store them for later consumption.
3. Winged seeds (e.g., maples) that are carried by the wind due to their lightweight and aerodynamic shape.
4. Berry seeds (e.g., tomatoes) that can be spread by water, animals, or human activities, often through consumption and subsequent excretion.

Each type has developed specific adaptations for effective dispersal in their environments.
