Plants spread seeds in many ways such as gravity, wind, hooks, animals, pepper pot, exploding, or floating.
The largest seed in the world is the double coconut. It measures up to 1.6 feet (50 cm) around the middle.
There were frozen seeds found in Canada, thought to be over ten thousand years old, and when they were defrosted and planted, they still grew.
If a seed is planted upside down, it will still grow right side up because seeds can sense gravity.
Some orchid seed pods hold over three million seeds inside of them.
If you shine a light on a plant from a sideways angle, the plant will grow towards the light and you'll end up with a sideways plant.
