usually, peas spread their seeds by self-ejection. when the peas mature, their pods will crack, and the seeds in the pods will be ejected, and then they will take root and complete the spread. In addition, peas are also likely to spread through birds. Birds eat peas in their stomachs and then excrete them.

What does pea use to spread seeds

There are two ways for pea to spread seeds: the first is to eject itself, and the second is to spread seeds by animals such as birds.

① Self-propagation

After the pea pods are dried by the sun and turn yellow, the pods will automatically burst outward, and the seeds inside will be ejected and fall to the ground. This mode of transmission is called self-propagation.

② Animal transmission

The second type is to spread seeds by animals such as birds. When peas are ripe, animals such as birds will come to eat them, but peas are not easy to digest. So the pea ran in the bird's stomach and slowly pulled out with the bird's shit.

Common modes of plant seed transmission

Self-transmission

Crops grow in various forms, while some crops can spread by themselves. As we know, some fruits and seeds have their own weight, and when they are ripe, they will fall directly to the ground due to gravity, such as persimmon and Gynura macrophylla. Some fruits will eject themselves, such as capsules and pods.

wind propagation

dandelion is the most common wind propagation. Because dandelion seeds look like wings and feathers, they can fly in the wind. In addition, the seed surface area and weight of some crops are relatively large, which can also be scattered with the wind and spread the seeds far away.

water transmission

some crops have waxy seeds on the surface that do not touch water, and their skins have air chambers, which can float on the water surface and spread through streams or ocean currents. This kind of seed is common in aquatic plants.

bird transmission

The fruits of some crops are fleshy, especially berries, drupes and hidden flowers and fruits. After eating these fruits, birds will excrete their seeds through the digestive tract at will. This kind of communication is the most advanced, because the way of communication is the farthest.

animal transmission

Some mammals like to eat fleshy fruit or dried fruits, such as macaques like to eat the fruits of persimmon and banana. So it can also help these plants spread.

adhesion spread

This crop is still relatively rare, and Xanthium sibiricum is the most common one. Because the fruit of Xanthium sibiricum has barbs, it can stick to people's clothes or animal hair. Then with the activities of animals and people, the seeds are carried to other places, which is also the mode of transmission.
