This is the result of DNA replication and 1 cell division. ... Meiosis is used to produce gametes which are sperm and egg cells, the cells of sexual reproduction.
They are similar because crossing over happens in both.
In multi-celullar organisms , the cell cycle produces groups of cells that perform the same function. These groups of cells form what it is called a tissue. A tissue is made up of cells that all are specialised to perform the same function. A bunch of tissues form an organ. Organs are more complex in structure and functions.
lots of different organs together form an organ system.
