In nature, all living things belong to living things. Organisms should be divided into several realms. Organisms that can survive and feed themselves are called plant realms, which are called plants for short.
Characteristics of plants: photosynthesis, six organs, roots as vegetative organs, etc. Most of the energy of green plants is obtained from sunlight through photosynthesis.
Plants have obvious cell walls and nuclei, and the cell walls are composed of glucose polymer-cellulose. In other words, it can use water, minerals and carbon dioxide to produce food with the help of light energy and chlorophyll that animals do not have.
After oxygen is released, glucose, an energy-rich substance, remains as a component of plant cells. Aristotle divided living things into plants (usually motionless) and animals (often moving to get food). In the Linnaeus system, it is divided into two fields: plant kingdom and animal kingdom.
Plants have the ability to adapt to the environment, but the intensity is not the same, which is ok in cities or farmland. They all need photosynthesis and the support of water during their growth. If plants never water, they will die. Moreover, we need sunshine, nutrients and air. Only in this way can we grow and reproduce better. Plants have a life cycle, but the length is different.
