How do plant seeds travel?

There are many wonderful ways for seeds that must spread on the surface of the earth. The lowest myxospores spread by peristalsis, that is, they permeate outward like spilled syrup; The most advanced seeds are spread through the feet or fur of animals. Some top seeds can catch birds' feathers and claws and travel for free; Some people get into the bellies of birds and animals to travel. It's really warm there, but it's too stuffy there. Squirrels carry and bury the fruits of many trees, such as walnuts, pine nuts and chestnuts, so they travel around with the seeds of trees for free. People call ants porters of nature. They bear hardships and stand hard work. They don't know how many seeds they take with them every day, and they are transported to different places to start a new life.

Seeds spread by animal fur must have tools that can catch animal fur. Think about it, if you ride on the fox's tail, it suddenly hears the barking of hounds; Or, if you ride on the rabbit's back, it suddenly hears the fox's cry. How dangerous! Therefore, this kind of seed should be prepared for the strangest trip. They prepared many claws, hooks, clips and thorns.

When people travel to the suburbs or climb mountains in the outer suburbs, they will spend a lot of time picking the seeds of Bidens bipinnata and Xanthium sibiricum from their socks. They travel on your legs and come to a new place.

If you have a chance to go hunting in Africa, you will find a plant that can catch other things. The seeds of this plant all have mane-like arms, and at one end of the arm there are claws that can hold the lion's fur tightly. Look how brave they are! Riding on the lion's mane is only more than one meter away from the lion's maw. The seeds of flax have long hooks that can be wrapped around the ponytail.

In addition, seeds spread by bird feathers are usually sticky, because feathers are too smooth for seeds to catch them easily. These sticky seeds stick to the feet and tails of birds, and sometimes they can fly from Heilongjiang to Hainan Island. Many birds can fly hundreds of kilometers a day, flying over mountains and oceans, so the seeds traveling on the birds' backs are happier than any other seeds.

Some seeds also spread in the stomachs of birds and animals. Guess what? This seed is wrapped in very sweet fruits, such as mulberry, strawberry and watermelon. Their shells must be very hard, like small wooden boxes, or like small grains of sand, so that they will not wear in the sand sac of birds and will not roll up and down in the acidic gastric juice of animals and be destroyed. Because they are so carefully protected, the nucleoli in the stone will not be harmed, and they can smoothly fall far away from home through the intestines and stomach of birds and animals and start a new life.
