➢Mitosis is important for sexual reproduction indirectly.
➢ It allows the sexually reproducing organism to grow and develop from a single cell into a sexually mature individual.
➢ Mitosis permits organisms to continue to reproduce through the generations.
➢ It is a same division through which identical daughter cells are produced having the same amount and type of genetic constitution as that of the parent cell.
➢ It is responsible for growth and development of multi-cellular organisms from a single-celled zygote. ➢ The number of chromosomes remains the same in all the cells produced by this division.
➢ Thus, the daughter cells retain the same characters as those of the parent cell.
➢ It helps the cell in maintaining proper size.
➢ Mitosis helps in repairing wear and tear in body tissues, replacement of damaged or lost part, healing of wounds and regeneration of detached parts (as in tail of a lizards).
➢ It is a method of multiplication in unicellular organisms.
➢ If mitosis remains unchecked it may result in uncontrolled growth of cells leading to cancer or tumor.
