The eukaryotic cell cycleThe cell cycle extends from the "birth " of a cell , resulting from cell reproduction , to the time the cell itself divides in two.
The eukaryotic cell cycle
Slide2Mitosis :-
All living cells arise from pre-existing living cells.
During an uninterrupted process of nuclear division known as mitosis, newly formed daughter nuclei receive the same diploid number (2n) of chromosomes as the parent cell.
Slide3Phases of mitosis
Slide4Meiosis
:-Meiosis, the process that produces haploid daughter cells in diploid
organisms, resembles mitosis, but with two special features, the first is the halving of the number of chromosomes ,and the second is an exchange of genetic material– pieces of chromosomes– between homologous chromosomes .
Slide5Slide6Slide7Gametogenesis :-
The production of gametes is called gametogenesis,
which includes oogenesis and spermatogenesis in human.Oogenesis:-Oogenesis is the development of eggs within the ovaries.Oogenesis

Spermatogenesis is the formation of sperm cells.
