structure X is the DNA or genetic material eg the chromosomes, which has to copy itself so that the new cell has information so that it can do basic funstions like respire. etc
So that the new cells have the same chromosomes as the parent cells.
Animal zygotes divide to form more cells. The zygote divides itself many times by mitosis until an embryo is formed.

After mitosis each daughter cell contains 46 chromosomes as the DNA replicates itself before the cell divides
When a cell divides into half, then two cells have emerged. The two cells can continue with the chain of dividing themselves into more halves. Each cell divides into two cells making a total of four cells. The number of cells that can cell can have when it divides, depends on how many times it has divided itself.
During Mitosis a cell splits into two identical new cells. The chromosomes copy themselves and then the cell divides in half. In Meiosis the diploid divides itself twice rather than once to create four haploid cells. This is the creation of sex cells.
Cytokenisis. Life of a cell; Interphase (growth, synthesize, growth... DNA making etc), Prophase, Metaphase, Anaphase, Telophase<cytokenisis happens in telophase; the cell splits in two.
A cell is a complete structure, it controls itself.
No. A cell membrane is a structure found in cells. It is not a cell in and of itself.
that would be binary fission....... resource: from my test :)
to reproduce
When a parent cell makes several nuclei and divides to make several daughter cells, it is called multiple fission. This process is common in some protists like amoebas and algae where multiple nuclei are produced before the cytoplasm divides to form several daughter cells.
