Importance of plants to human beings

  1. Plants take in carbon dioxide and give off oxygen. Animals take in oxygen when they breathe. Cells need oxygen, and they use gas to get the energy they need to do their work.
  2. During photosynthesis, plants take in carbon (IV) oxide, which helps lower the amount of carbon (IV) oxide in the air. When carbon (IV) oxide builds up in the atmosphere, it keeps the heat from the sun and creates a greenhouse effect.
  3. Plants are the only source of food for all other living things. Herbivores eat only plants, while carnivores eat animals that eat plants. Humans, on the other hand, can eat both plants and animals.
  4. Medicines have been made from plants like ginger, bitter leaf, garlic, etc.  Plants are used to make drinks like tea, coffee, wine, beer, fruit juice, and barley. 
  5. Plants can also be used to make wood, paper pulp, cotton, tannin, linen, etc.
