1. After mitosis, two cells are obtained, and after meiosis, four.
2. After mitosis, somatic cells (body cells) are obtained, and after meiosis, germ cells (gametes are sperm and eggs; plants produce spores after meiosis).
3. After mitosis, identical cells (copies) are obtained, and after meiosis – different ones (hereditary information is recombined).
4. After mitosis, the number of chromosomes in daughter cells remains the same as in the mother cells, and after meiosis decreases by 2 times (there is a reduction in the number of chromosomes; if there weren’t, then after each fertilization the number of chromosomes would double); alternation reduction and fertilization ensures a constant number of chromosomes).

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.
