Essay on Plants |Benefits, Uses & Importance of Plants

Every tree that we see around us was a tiny plant some years ago. The countless benefits of plants cannot be neglected. They are the main source of food for all living beings. They may not depend on us but our lives depend on them for sure. There are more than 300 thousand species of plants on this planet. When a plant grows, it makes the area around it greener and beautiful. It is a fact that people who live closer to greenery are healthier and happier than people who do not live near greenery. Composition of Plants

A plant has around 95% of water. Plants need water, soil and sunlight for their survival. They will die in absence of these things. They have a waxy layer of their surface to prevent them from drying out. They prepare their own food in the presence of sunlight by a process called ‘photosynthesis’.
There is a pigment in plants to give them green color which is called ‘chlorophyll’. They also have a well-developed metabolic system which includes anabolism as well as catabolism.
Importance of Plants
The importance of plants in our life is inexhaustible. They are very important for survival of every specie living on Earth. They provide us food, shelter, habitat and medicines.
Just a single tree can provide food and shelter to many species like insects, birds and reptiles.These green plants produce food for all organisms and these foods are rich in vitamins and carbohydrates that are necessary for our health.
We get clean water because of plants. They move water from soil to atmosphere through a process called transpiration.
Without plants, our water cycle will be disrupted and our oxygen supply will be cut short because they improve oxygen level and reduce carbon dioxide level. In short, we will not be able to survive without plants.
Plants maintain balance in ecosystem. They also help to purify the air that we breathe. They help to fight global warming by maintaining the global temperature to save us from scorching heat.
They also cool down the air as they lose moisture and reflect heat upward through their leaves. They maintain a balance in temperature by reflecting harmful radiations of sun. They play an important role to convert carbon dioxide to oxygen through a process called ‘photosynthesis’.
So, more trees mean more oxygen and less carbon dioxide in atmosphere. If there are less plants that means there will be more carbon dioxide in air and with more CO2, more of sun’s radiations will be reflected to earth, instead of space.
These radiations will cause our average temperature to rise. As a result, the oceans will be warmer and at some point, we will all fry to death.
The importance of plants is not just limited to being a source of food or oxygen. Plants are also used for various medicinal purposes.
These medicines are safer because of lower side effects. There is a therapy called herbal therapy that is one of the oldest types of treatments this world has ever known. Herbal remedies have proven to be genuine and more effective.
Conclusion
Plants are very important for survival of living beings. It is because of plants that we breathe fresh air. It is our responsibility to take care of plants because our lives depend on their survival. Without them, every specie will die because of lack of oxygen on planet.
Unfortunately, people cut down these trees to make furniture and other wooden materials. We need to understand that plants also have a life. Therefore, it is very important to have awareness about plants and taking necessary measures to promotes tree plantation.
