Give examples of nuclear-free cells. Explain the reason for their nuclear freeness. What is the difference between life of nuclear-free cells from cells with a nucleus?
Prokaryotes – cells of microorganisms, instead of the nucleus containing chromatin in the cell, which contains hereditary information.
In eukaryotes: mammalian red blood cells. At the site of the nucleus, hemoglobin is located in them and, therefore, the binding of O2 and CO2 increases, the oxygen capacity of the blood — gas exchange in the lungs and tissues proceeds more efficiently.
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.
