How do flowers spread seeds?

Different flowers have different seed transmission methods, such as animal transmission, wind transmission, water transmission and ejection machinery transmission.

1. Rely on water to spread

Coconut: spread by water. After the coconut is ripe, the coconut falls into the sea and floats far away with the sea; the fruit of water lilies sinks to the bottom after ripening. When the pericarp is rotten, the seeds covered with a spongy outer seed coat float and float elsewhere.

2. Spread by birds or other animals

Cherries, wild grapes, wild ginseng rely on birds or other animals to eat seeds into their stomachs, and because they cannot digest them, they are excreted and spread in all directions; pine nuts are taken away by squirrels when they store food for the winter.

3. Spread by the wind

The red willow spreads its seeds to the distance by the flying of catkins.

4. Mechanical transmission

The fruit of impatiens will crack and send bullets in all directions, which is the way to mechanically spread seeds.
