Photosynthesis for Kids

In science, photosynthesis is defined as 'a process wherein the synthesis of compounds is facilitated with the aid of radiant energy, usually in plants, but also in some species of algae and bacteria'. Even though this is an apt definition of the process, it would be a bit harsh on our part to expect the kids to grasp the same. The ideal definition of photosynthesis for kids would be a process by which plants capture sunlight and use it to convert carbon dioxide and water into food. Given below is the simplified version of the photosynthesis process, intended to make the concept easier for the kids to understand.

Photosynthesis for Kids
Going by the simplest possible definition, photosynthesis is the process by which plants convert the carbon dioxide into their food, with the help of the energy derived from the Sun. The most essential components of this process include direct sunlight, water, carbon dioxide and chlorophyll. Other than the plants, even some algae and bacteria species resort to this process in order to generate food. That, however, doesn't mean that only these plants and organisms benefit from this process. Various other living beings, including humans are either direct or indirect beneficiaries of the process of photosynthesis.

Steps of Photosynthesis for Kids
The leaves and stem of the plants have microscopic holes, which are known as stomata, from which the carbon dioxide enters these plants. At the same time, water enters the plant through their roots. After being absorbed by the roots, this water travels all the way through the stem to reach the leaves. The leaves of the plant derive the green color owing to the presence of a green pigment, known as chlorophyll, in them. When the sunlight falls on the leaves of the plant, this chlorophyll captures the energy in it, and stores it for further use. This energy is eventually used to convert water into hydrogen and oxygen. This hydrogen is combined with the carbon dioxide in order to produce the food for the plant, whereas the oxygen, which is a by-product of the entire process, is let out through the stomata. The same process is carried out in organisms like bacteria and algae, wherein hydrogen is used to produce food, and oxygen is let out as a waste product. Going through the diagram of photosynthesis for kids given above will make the concept easier for you to understand.

Importance of Photosynthesis for Kids
The process of photosynthesis is as important for the humans and animals, as it is for the plant growth process. Other than glucose, which is an important source of carbohydrates, photosynthesis also produces proteins, fats and water soluble sugars. We cannot produce these nutrients on our own, and hence have to depend directly on plants, or other animals which feed on these plants, to derive them. Photosynthesis is vital to facilitate the process of respiration in humans and animals as well, as our oxygen requirements are fulfilled by the oxygen produced during this process. This process also regulates the amount of carbon dioxide in the atmosphere, and any fluctuations in the same can result in adverse effects on the environment.

This was brief information about what is photosynthesis. For kids, understanding the process by which the plants produce their food can be fascinating enough. However, they also need to understand the importance of photosynthesis for humans and other animals. The basic fact is that the process of photosynthesis plays a crucial role in making our planet the only planet with life. That being said, the onus is on us to ensure that this process continues undisturbed, as any hindrance in the same is bound to result in direct consequences on our life.
