Nature can be infinitely beautiful with its colors and showy plants. But among fragrant flowers and green leaves, we easily forget that plants are an absolute necessity for life on earth.

Where do we humans really get the energy we need? Well, the energy we get from the sun and it is photosynthesis that with the help of energy from the sun converts carbon dioxide and water into oxygen and dextrose or glucose as it is also called. When we then eat, the glucose in our cells is converted into energy, water and carbon dioxide. It can be said that this is photosynthesis but vice versa. Target group: from 12 years, Duration: 3 minutes.
