What is Photosynthesis

In the process of photosynthesis, plants turn simple carbon dioxide into high-energy compounds. They absorb the carbon dioxide from the air. The energy for this is provided by sunlight. The Greek word “photo” means light, the word “synthesis” means “composition”. So something is put together with the help of light.

Photosynthesis occurs in the green parts of plants. They are green because they have small green dye parts in their cells. This dye is called chlorophyll. It first breaks down the carbon dioxide and then reassembles it into glucose with the help of sunlight. In German, glucose is simply called glucose. For this procedure, the plant additionally needs water, which it absorbs with the roots.

During photosynthesis, another substance is produced, namely oxygen. But the plants do not need it at all. That’s why they’re putting him back in the air.

For us humans, photosynthesis is so important because we and all animals do exactly the opposite of plants when we breathe: we need the oxygen that we breathe in through the air. When we exhale, carbon dioxide enters the air again. This is a cycle in nature that never stops.

However, humans and animals also use the sugar produced by photosynthesis. Namely, it turns into vegetables, fruits, cereals and many other foods. But also wood, cotton and many other things are created only with the help of photosynthesis.

Without air, we could not live on Earth. Oxygen is needed for a person to breathe. Plants do not need oxygen to live, they release the oxygen to the environment. This process is called photosynthesis. It is chemical and takes place in the plant.

The rain forests bring us the most oxygen. Tropical rainforests are found mainly in Asia and South America. There are so many trees and plants growing there that they can supply the whole world with oxygen. For this reason, the Amazon rainforest is also called the “Green Lung of the Earth”.

For a better picture in your head: a one-hundred-year-old beech tree emits as much oxygen as 50 people need to breathe in one hour.

How does photosynthesis work?

The process of photosynthesis needs sunlight, carbon dioxide and water. The process takes place in the chloroplasts of the leaves. The chloroplasts are a component of the plant cell. There is the dye chlorophyll. The chlorophyll gives the leaves their color. In addition, the chlorophyll is needed to form glucose and oxygen with the help of light, water and carbon dioxide. The green dye turns the sunlight it receives into chemical energy.

First, the carbon dioxide is split and, with the help of light, is assembled into glucose. The plant also needs water for the process. It takes this up through the roots.

In the end, the plants release the oxygen to the environment, because they can not do anything with it. They need glucose to continue growing, so the process is also necessary for the plant world. Glucose is glucose that can be converted into starch. With this starch, the plants can get to fats and protein substances. This is the food for plants.
