Significance of Photosynthesis
Photosynthesis is the process by which plants and other things make food. It is a chemical process that uses sunlight to turn carbon dioxide into sugars the cell can use as energy. As well as plants, many kinds of algae, protists and bacteria use it to get food.
Photosynthesis is very significant for life on Earth. Most plants either directly or indirectly depend on it. The exception is certain organisms that directly get their energy from chemical reactions; these organisms are called chemoautotrophs.
There are three main factors affecting photosynthesis:
Photosynthesis can happen in different ways, but there are some parts that are common.
Photosynthesis is important because all living things need oxygen to survive. All producers make oxygen and sugar for the secondary consumers and then the carnivores eat animals that eat the plants.
- 6 CO2(g) + 6 H2O + photons → C6H12O6(aq) + 6 O2(g)
- carbon dioxide + water + light energy → glucose + oxygen
Photosynthesis is important because all living things need oxygen to survive. All producers make oxygen and sugar for the secondary consumers and then the carnivores eat animals that eat the plants.
Plants make their own food and pass their energy down to humans when we consume the nutrients from the plants. Photosynthesis creates clean air for humans to breathe. It also allows plants to grow, which feeds humans. It also produces oxygen which is the gas we need to live.Factors affecting photosynthesis
There are three main factors affecting photosynthesis:
- Light intensity
- Carbon dioxide concentration
- Temperature
Significance of Photosynthesis in points
- Photosynthesis helps in the conversion of solar energy into organic matter.
- Photosynthesis consumes atmospheric carbon dioxide and yields carbohydrates and molecular oxygen.
- Photosynthesis evolves molecular oxygen for use by other living organisms and maintains the level of atmospheric oxygen which is continuously consumed by plants and animals during respiration.
- Photosynthesis produces carbohydrates and used by plants and animals to synthesize organic acids, proteins, fats, nucleic acids, pigments, hormones, vitamins, alkaloids and other metabolites
Significance of photosynthesis
ReplyDelete1. Photosynthesis is a source of all our food and fuel. It is the only biological process that acts as the driving vital force for the whole animal kingdom and for the non-photosynthetic organism.
2. It drives all other processes of biological and abiological world. It is responsible for the growth and sustenance of our biosphere.
3. It provides organic substances, which are used in the production of fats, proteins, nucleoproteins, pigments, enzymes, vitamins, cellulose, organic acids, etc. Some of them become structural parts of the organisms.
4. It makes use of simple raw materials such as CO2, H2O and inexhaustible light energy for the synthesis of energetic organic compounds.
5. It is significant because it provides energy in terms of fossil fuels like coal and petrol obtained from plants, which lived millions and millions of years ago.
6. Plants, from great trees to microscopic algae, are engaged in converting light energy into chemical energy, while man with all his knowledge in chemistry and physics cannot imitate them
