Cell theory includes the following key points:
– A cell is an elementary unit of the living, capable of self-renewal, self-regulation and self-reproduction and is a unit of the structure, functioning and development of all living organisms.
– The cells of all living organisms are similar in structure, chemical composition and basic manifestations of life.
– Cell reproduction occurs by dividing the original mother cell.
– In a multicellular organism, cells specialize in functions and form the tissues from which the organs and their systems are built, interconnected by intercellular, humoral and nervous forms of regulation.
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.
