Expand the biological significance of mitosis for single-room and multicellular organisms.

Mitosis is a division in which an absolutely identical daughter is obtained from the mother cell. It consists of 4 phases, preceded by interphase: prophase, metaphase, anaphase and telophase.

1) For unicellular mitosis is a way of asexual reproduction. From one cell, two identical ones turned out.

2) In multicellular organisms, due to the complex structure and the appearance of sexual reproduction, mitosis can perform several functions: an increase in the number of somatic cells (for example, skin cells) for the growth of organs and their regeneration, the regeneration of the whole organism from a part (for example, from flat parts) or individual parts (tail in lizards) and asexual reproduction.
