How do seeds germinate?

Seeds begin to germinate if the soil in which they lie is warm and moist. First, the sprout feeds on the supply of "food" that is in the seed.

But as soon as the first leaves appear in the plant, it begins to produce food itself. Seeds of chestnuts are covered with a hard brown shell. Over the winter, this shell rots, and the seeds take root.

The seed swells in the water and its shell cracks. A root grows out of the alkali. The root branches out in tiny hairs. A sprout appears. He reaches up and makes his way out of the ground.

Do all plants come from seeds?

No, not all. For example, wild strawberries propagate by lateral shoots - a mustache. When the mustache touches the ground, it takes root. And after two or three weeks, the new plant is completely ready for an "independent life."

The largest seeds are in the giant fan palm. Their weight is 20 kilograms
