List current principles of cellular theory

– A cell is an elementary unit of the living. The cell is the smallest structural and functional unit of the living and is an open, self-regulating, self-reproducing system. There is no life outside the cage.
– All cells are similar in their chemical composition and have a general structural plan. The general principle of cell organization is determined by the mandatory functions necessary to maintain one’s own life. However, the cells have specific features associated with the implementation of special functions by the cells and resulting from cell differentiation.
– A cell comes only from a cell. Reproduction (increase in the number) of cells occurs only by dividing the previous cells. The billions of cells that make up a living organism have arisen as a result of the division of a fertilized egg (zygote), so all cells in the body are genetically the same.
– Multicellular organisms are complexly organized integrated systems consisting of interacting cells. In addition to cells, multicellular organisms include non-cellular components and giant multinuclear formations. A multicellular organism has new specific features and properties that are not a simple summation of the properties of its constituent cells.
– A similar cellular structure of organisms is evidence that all living things have a common origin.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
