Food

Plants are the main source of food for humans. Plants, unlike humans and animals, manufacture their own food. They do so by the process known as Photosynthesis in their green leaves by use of sunlight.  They can convert and store the Light energy in the form of Carbohydrates. This process takes place in the leaves (chlorophyll) by use of carbon-dioxide and water.

From this manufactured food, they consume some of it and store the remaining. This is stored in the form of fruits, seeds, tuberous roots, etc. This fruits and other parts of plants are consumed by humans. The food is in the form of vegetables, fruits, grains, Cereals, leaves, seeds, mushrooms, etc.

Furniture & Shelter

Plants are the important source of furniture. The plant wood is used to build houses and also to make other furniture items.

Importance of Plants in nature

Environment and the Climate are interlinked mainly with plants. The presence of plants influences Rainfall, humidity, and temperature. Cutting down plants also imbalance the environment which will indirectly affect human life.

In cities and towns, there is a rise in gaseous pollution like(CO2, CO, SO2, etc.). So city environments are highly polluted and unsafe for living.  This is due to automobiles and factories ejecting toxic gases and also reducing the healthy Oxygen ratio of air. Air Pollution causes diseases of various types. So growing plants on the roadside, parks, etc. helps minimize the gaseous pollution. For the benefit of plants oxygen, they can even be grown in office, residential areas, Education institutes, etc. For this, we can use low maintenance plants like indoor potted plants, hanging plants, etc.
