Nutrition in plants is a very special vital function. Why? Animals need to eat plants or other animals; but plants can make their own food. Isn't it fantastic?

How can plants make their own food? They can do it thanks to the photosynthesis. In the photosynthesis, plants use water, minerals (nutrients), carbon dioxide and sunlight. Let's explain the photosynthesis!!



1 - Plants absorb water and minerals from the soil using their roots. That is what we call raw sap (water + minerals).

2 - Then, the raw sap goes up through the stem to the leaves.

3 - In the leaves, plants absorb sunlight and carbon dioxide (in the photosynthesis, plants absorb carbon dioxide and release oxygen to the atmosphere).

4 - The raw sap mixes with the sunlight and the carbon dioxide, transforming the raw sap into elaborated sap (raw sap + sunlight + carbon dioxide).

5 - The elaborated sap is the plant's food. It goes from the leaves to the rest of the plant.
