What is Photosynthesis? Reaction and Gasses Involve During Photosynthesis Process

What is Photosynthesis?

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of organic molecules such as glucose. Carbon dioxide and water are converted into glucose and oxygen during photosynthesis.

The process of photosynthesis involves two main stages: the light-dependent reactions and the light-independent reactions. During the light-dependent reactions, light energy is absorbed by chlorophyll molecules in the chloroplasts of plant cells, and this energy is used to generate ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). The ATP and NADPH produced in the light-dependent reactions are then used to power the light-independent reactions, also known as the Calvin cycle, which produces glucose and other organic molecules from carbon dioxide and water.

Photosynthesis is a vital process for the survival of most life on Earth, as it is the primary means by which energy enters the ecosystem. Plants use the glucose produced by photosynthesis as a source of energy for growth and reproduction, and the oxygen released during photosynthesis is essential for the survival of most animals, including humans.

Type of gasses release during photosynthesis.

During photosynthesis, plants release oxygen gas (O2) as a byproduct of the light-dependent reactions. This oxygen is released into the atmosphere and is used by animals and other organisms for respiration.

In addition to oxygen, plants also release small amounts of water vapor (H2O) during photosynthesis, as water is used as a reactant in the light-dependent reactions. However, the majority of the water used during photosynthesis is actually retained by the plant and used for various cellular processes.

It's worth noting that during cellular respiration, which is the process by which organisms convert glucose and oxygen into energy, carbon dioxide gas (CO2) is released as a byproduct. So while photosynthesis releases oxygen and water vapor, cellular respiration releases carbon dioxide. These two processes are interconnected and help to maintain a balance of gases in the atmosphere.

Is It Possible Photosynthesis Process Without Sun?

Photosynthesis is a process that is powered by light energy, typically from the sun, so it is not possible for photosynthesis to occur without some source of light. However, it is worth noting that some organisms, such as certain types of bacteria, are capable of carrying out a form of photosynthesis called "anoxygenic photosynthesis" that uses different wavelengths of light than those used by plants and algae.

Anoxygenic photosynthesis can occur in the absence of sunlight, using other sources of light such as infrared light or light produced by chemical reactions. However, this form of photosynthesis is not as efficient as the type carried out by plants and algae, and it is typically only found in specialized organisms that live in extreme environments where other sources of energy are scarce.

Overall, while some organisms can carry out forms of photosynthesis without sunlight, the vast majority of photosynthesis on Earth is powered by sunlight, and it is a critical process for the survival of most life on the planet.
