Answer:
1. Life cycle of a cell starts from
G1 phase - S phase (synthesise phase) - G2 phase - mitosis.
2. By mitosis bcoz it restore nucleo cytoplasmic ratio means ploidy of cell remain same.
3. Bcoz of transformation of normal cells into cancerous cells by Carcinogens present in tobacco.,drugs .etc
4 mitosis occurs in plants animals
Binary fission occurs in bacteria and other single celled organism.
.
Both give rise to two daughter cells.
5.sex cells (n) are produced by meiosis from gamete mother cells(2n).
6.in meiosis ploidy of cell become half
Means diploid cell form haploid cells
And 4 haploid daughters cells are formed.
In mitosis, ploidy of cell remain same
Means haploid form haploid and diploid form diploid.
1 cell form 2 daughter cells.
Hope this helps you.. Frnd ❤️
