Mother plant has an idea.

"Plant Mother has a Way" comes from the first volume of the second grade of People's Education Publishing House (including 20 17 edition). The Chinese textbook "Plant Mother has a Way" is a poem, which vividly expresses scientific knowledge in the form of verse by personification, and the language is catchy. It is a popular science work that I can never get tired of reading. This text vividly tells how dandelion, xanthium sibiricum and pea spread their seeds.

Mother plant has an idea. If the child grows up,

You have to say goodbye to your mother. There are homes everywhere.

Cattle and horses have feet, birds have wings,

Is there any way to travel with plants?

Mother dandelion prepared a parachute,

Give it to your doll.

As long as the wind blows gently,

The children set out in succession in the wind.

Mama Xanthium has a good idea.

She dressed the child in barbed armor.

As long as you hang animal fur,

Children can go to fields and valleys.

Mother pea has a better idea.

She put the pod in the sun,

Bang, the pod exploded,

The children skipped away from their mother.

There are many ways for plant mothers.

Look carefully if you don't believe me.

There is a lot of knowledge there,

Careless children can't get it.

Methods of Plant Mother Spreading Seeds Dandelion Mother Spreading Seeds with the Wind; The mother of Xanthium sibiricum hangs the fur of animals with small thorns to spread seeds; Mother pea spreads seeds by elasticity.

Other ways for plants to spread seeds: hydraulic transmission.

Coconuts are spread by water. When the coconut is ripe, it falls into the sea and drifts away with the sea. When the fruit of the water lily is ripe, it will sink to the bottom of the water. After the pericarp decays, the seeds covered with spongy exocarp will float and drift to other places.

Animal transmission

Cherry, wild grape and wild ginseng are eaten by birds or other animals. Because it can't be digested, it is discharged with feces and spreads in all directions. ; Pine nuts were taken away by squirrels when storing winter grain; When butterflies and bees collect nectar, flowers spread through pollen.

wind dispersal

Willow spreads seeds far away through flying catkins; Dandelion is also spread by the wind.

Mechanical communication

The fruit of impatiens will bounce off, crack and shoot a bullet in all directions. This is a method of mechanical sowing.
