Photosynthesis and cell respiration are complementary processes in which organisms acquire desired substances. They all consume and produce the same way (water, glucose, oxygen, carbon dioxide) in various ways. Through these processes plants will get the carbon dioxide they need, and organisms will get the oxygen they need. They are also necessary for energy exchange necessary for living to survive.
Photosynthesis is the process by which green plants produce their own food by converting light energy into chemical energy. Leaf chlorophyll converts carbon dioxide, water, minerals to oxygen and glucose. Photosynthesis occurs in the chloroplasts of cells. This process provides energy directly or indirectly to all living creatures. Without it, life on Earth will not exist.
Cell respiration, on the other hand, is a process by which living creatures convert oxygen and glucose to carbon dioxide and water to generate energy. It does not require the presence of sunlight and always occurs in vivo. Cell respiration occurs in cell mitochondria
Photosynthesis requires energy and produces food, but cell respiration breaks down food and releases energy. Plants do photosynthesis and breathing, but animals can breathe only.
Photosynthesis and cellular respiration are interdependent. Energy conversion that occurs in photosynthesis is used to promote reaction in cell respiration. Let's see an example. Grass is a plant that uses photosynthesis to make its own food. When it converts light energy into chemical energy in the form of glucose, glucose is used to form a new plant structure and the lawn grows. Outdoor cattle eat grass and break down glucose during cell respiration. The chemical energy of glucose is converted to ATP and used to power cows to live and grow
Photosynthesis is the process of converting light energy into chemical energy in the form of glucose called chloroplast. Glucose produced by photosynthesis is then used during cell respiration. In cellular respiration, the energy stored in the binding of glucose molecules is resolved and converted to another type of energy ATP. Both photosynthesis and cellular respiration start with one energy and convert it to another energy, but the type involved is different. Photosynthesis uses light energy to create complex molecules in anabolic reactions, cell respiration breaks down these molecules and releases energy in catabolic reactions.
