Explanation
The process in which light is converted to energy is known as photosynthesis. This energy is later used by living organisms to fuel their organic activities. The chemical energy from this process of photosynthesis is stored in the forms of sugar and carbohydrate molecules. This is then synthesized from carbohydrate and water. This is where the name photosynthesis originates from. Photo means light, while synthesis means the combination and putting together something. Oxygen is released as a by-product of the process of photosynthesis. This is the oxygen that most living organisms, most especially animals, depend on. Most algae and cyanobacteria perform the process of photosynthesis. These organisms are known as photoautotrophs. It is important to note that photosynthesis contributes highly to the oxygen content on the earth’s atmosphere. Most living organisms are dependent on this process.
It is essential to note that photosynthesis can be performed differently by different organisms. However, this process begins with the conversion of light to energy. The light-matter is absorbed by chlorophyll which is a green matter contained in most plants. The chlorophyll is held in the chloroplasts which are found in leaves. Chloroplasts are abundant in most green plants. In bacteria, these chloroplasts are located in the plasma membrane. This reaction can be termed as a light-dependent reaction. This is because it depends on the light on a more substantial basis for this process to be completed. In some of the light-dependent reactions, some energy synthesized is used in the stripping of oxygen electrons from substances such as water. This process also involves the splitting of water. Two hydrogen compounds are created as a short term reservoir of energy. This splitting of hydrogen compounds is used in the creation of two compounds known as Adenosine Triphosphate and nicotinamide adenosine dinucleotide.

General usage
The process of photosynthesis is used to provide oxygen for all living organisms. The carbonic cycle would not be possible without the process of photosynthesis. Organisms that require oxygen for their survival would die, including plants. It is important to note that green plants depend hugely on photosynthesis as a way of making their food.
Photosynthesis is essential due to the following reasons;
It is a source of oxygen in the atmosphere for both plants and animals.
It highly contributes to the oxygen cycle between the ocean, animals and plants.
It indirectly and directly affects life on earth.
It provides energy for most plants, animals and humans.
It is important to note that photosynthesis allows for energy extraction through the Adenosine Triphosphate produced during the process of photosynthesis. Living beings take part in the process of photosynthesis, either directly or indirectly. This part will explain the importance of cellular respiration and its usage for living organisms. Cellular respiration involves three critical steps. The process of glycolysis is the first step. This involves the breaking down of glucose to produce pyruvate molecules and a bit of adenosine triphosphate. The second step involves the transportation of pyruvate molecules to the mitochondria. The process of anaerobic respiration occurs, which consists of the transport of energy into the mitochondria without the use of oxygen. The third step of cellular respiration requires oxygen, and this is the process of aerobic respiration. The food energy enters the electron chain transport and aids in the production of ATP
Cellular respiration is the opposite of photosynthesis in plants. Living beings breathe in oxygen from the process of photosynthesis and give out carbon dioxide. Carbon dioxide is used in the process of photosynthesis to make foods for the plants. This explains the symbiotic relationship between animals and plants. These processes depend on each other. In essence, the photosynthesis process is used in the process of cellular respiration.
Part of biology
Biology describes the different living organisms that exist together in the world today. Photosynthetic plants are known as photoautotrophs. It is important to note that not all plants use carbon dioxide to carry out the process of photosynthesis. Photo heterotrophs use organic compounds as a source of carbon. Algae and cyanobacteria release oxygen into the atmosphere through the process of oxygenic photosynthesis. This is the most common type of photosynthesis employed by living organisms. It is important to note that there are different varieties of oxygenic photosynthesis used by living organisms. This is most common in the types of bacteria that consume carbon dioxide instead of synthesizing it.
The process of photosynthesis is used in biology to explain the relationship between human beings or rather animals and plants. Animals and plants co-exist peacefully and are dependent on each other. Plants depend on animals for carbon dioxide, while animals depend on oxygen for breathing and life. The process of photosynthesis is also used to explain the process by which plants make their food. It is important to note that plants use this process majorly as a source of food and energy. Animals, including human beings, obtain food from animals. This is because plants store their food in places such as roots and stems of plants. In essence, the process of photosynthesis is used to explain the relationship that exists between man and plants. It also helps us understand plants and the different processes that occur in the course of a living organism.
