The relationship between plant vegetative growth and reproductive growth is interdependent. The division between vegetative growth and reproductive growth of crops is usually based on flower bud differentiation, which used to be called vegetative growth and later belonged to reproductive growth. Actually, there is no strict boundary between vegetative growth and reproductive growth. For a considerable period of time, vegetative growth and reproductive growth were carried out at the same time, and there was obvious competition for nutrients.

It has obvious cell wall and nucleus, and the cell wall is composed of glucose polymer-cellulose. Plants have the ability of photosynthesis-that is, they can use light energy and chlorophyll that animals don't have to produce food by using water, minerals and carbon dioxide. After releasing oxygen, glucose, an energy-rich substance, remains as a component of plant cells.

The ancestors of all plants are unicellular non-photosynthetic organisms, which swallowed photosynthetic bacteria and formed a mutually beneficial relationship: photosynthetic bacteria live in plant cells. Finally, bacteria become chloroplasts, which are organelles that exist in all plants but cannot survive independently.
