The growth of a green plant

Do you really know how a green plant can grow? Some people thought they knew the answer already. Some people might say the answer is because we give water to the plant, or because of the sun, or because the plant takes substances from the soil to grow. None of these answer is wrong, but still cannot explain how. In this article, we will start an easy learning about how a green plant grows.

The first investigation about a green plant was set up by a Belgian scientist named Jan van Helmot in the year of 1605. He found that a willow tree took substances from the soil to grow. He found that plants needed water to dissolve the substances in the soil.

Green plants take two kinds of substances from the soil. One is called Nitrates, which are compounds of Nitrogen and Oxygen. The other one is called Phosphates, compounds of Phosphorus and Oxygen. Different kinds of plant needs different amount of these substances. As a green plant grows, the substances in the soil will be decreasing. That is why we need Fertilizers as an addition substances to be put back in the soil.

First investigation had proven that green plants need water to dissolve the substances, that is why we need to water the plant. But after many investigation, it was found that green plants also use substances that they took from the air, called Carbon Dioxide. Green plants can make foods for their lives such as sugars and starches from carbon dioxide and water.

But not only that, green plants also need heat and light to make food from substances dissolved in water and from Carbon Dioxide in the air. The heat and light that green plants need is come from the Sun.

Now we know what makes green plants grow. The information presented above will do one of two things: either it will reinforce what you know about  or it will teach you something new. Both are good outcomes.
