Living cells breathe, feed, grow and multiply. In any living cell, complex and diverse reactions necessary for its vital activity are constantly carried out.
A cell is a small organism. In both multicellular and unicellular creatures, the cell produces its energy, breathes, feeds and releases metabolic products through the cell pores. Each organoid performs its functions: vacuoles accumulate various products of substances, the cytoplasm provides their movement, etc. With direct exposure, the cell is capable of being irritated. The nucleus stores information (DNA), which, during its division (cell reproduction), transfers its data to the new cell.
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.
