Bioenergetics: Photosynthesis and Energy Flow

Conclusion

The simplest way to understand what photosynthesis is, would be to know that it refers to the process of producing and releasing oxygen into the air. It is a process performed by plants to produce their own food, and it requires direct sunlight, carbon dioxide, and water (H2O). In the process of photosynthesis, plants decompose the molecules of hydrogen and carbon dioxide into hydrogen, carbon, and oxygen, to produce glucose, which forms the source of their energy, growth, and food.

Significance of Photosynthesis in Life
Photosynthesis is directly related to the life and survival of all the other living creatures on earth. It not just supplies oxygen, without which, breathing and being alive would be difficult, but it also supplies food and energy to all.


Among all the living organisms on planet earth, only plants are capable of producing their own food and deriving energy from it. No other living creature can produce their food and thus, depend on plants or other creatures which feed on plants to survive. Therefore, by producing energy, the plants supply all the necessary nutrients and energy directly and/or indirectly to the other living creatures. The production of this energy is possible through photosynthesis.


Going by all the above facts, it is evident how photosynthesis plays a vital role in regulating the life cycle on Earth. Now you may realize its importance every time you breathe in and out, and take a look at the plants at your backyard, neighborhood, or front garden. Sunlight, water, and plants work together to supply the raw source of energy to us, and help us breathe in oxygen to live on. Life without photosynthesis would thus be impossible.
