Answer   Reasons why it's called 'plastic surgery.'   * It's a Greek word 'plastikos' meaning to mold or shape.  * Plastic surgery dates back centuries. Ancient â¦ India skin grafts were used for reconstruction purposes. Romans repaired damaged ears of soldiers.  * Plastic surgery was inspired by war.
Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of interphase. During prophase, the parent cell chromosomes â which were duplicated during S phase â condense and become thousands of times more compact than they were during interphase.
In meiosis, A cell undergoes reduction division and, a human cell which is of 46 chromosomes, forms 4 cells of 23 chromosomes each. During the union of Gametes, 23 chromosome from the father's sperm and 23 from mother's egg cell fuse to form a diploid zygote of 46 chromosomes, and later embryo. If this meiosis doesn't happen a child would be having 92 chromosomes which is impossible at all costs. Hence meiosis is essential.
