What is a plant? 

Kingdom Plantae includes multicellular, autotrophic organisms. Plants have a basic metabolism, the ability to sexually reproduce, the ability to respond to the environment, diversity and evolution just like other organisms in other kingdoms.However, plants are the primary producers in food webs and oxygenation of the atmosphere.

Plants are everywhere. They are not only beautiful to observe, plants replenish our supply of oxygen, which they give off during photosynthesis, and give off water, which lowers the temperature of the air. Plants are the food source of many other living things, and are what makes life on our planet possible for other organisms.
