About 250,000 species of seed bearing plants
Seeds of legumes, such as beans and peas, typically have hard seed coats. Other species with hard seed coats include sunflowers, squash, and nuts like acorns and pecans. Hard seed coats help protect the seed from injury and ensure proper germination conditions are met.
Softening of seed coats helps the seed germinate. After soaking the seed in hot water (do not boil), for 5-6 hours the coat will soft. Plant immediately after taking the seed out of the water.

Monocotyledon seeds have a single seed leaf, making them generally easier to split open compared to dicotyledon seeds, which have two seed leaves. The structure of monocot seeds is simpler, allowing for easier access to the embryo inside. Dicot seeds, on the other hand, tend to have harder seed coats that may require more effort to split open.
To crack open a peach seed, you can use a nutcracker or a hammer to carefully apply pressure until the seed cracks open. Be cautious not to damage the seed inside.
Hooks and spikes on a seed are used for their dispersal.They can attatch themselves on the furry coats and get carried over long distances.
