What are the main distinguishing features of animals?

Animals are characterized by a special way of feeding. Namely, nutrition only with already synthesized substances (they do not form nutrients for themselves from minerals through photosynthesis). All animals do not live long periods of time. Representatives of animals move around and they have organs and devices for this. Storage substances in animal cells are different from plants. There is no strong shell in the cage. In addition, there are no plastids and vacuoles in the cells. There is a cell center. Despite the external differences between plants and animals, they have some similarities in chemical structure and life.
