Cells...Mitosis

A cell is the smallest living organism and it is often called the building block of life.

Cells divide by mitosis.



Mitosis is a process which results in the production of two daughter cells from a single parent. The daughter cells are identical to one another and to the original parent cell.

Interphase: The cells cromosomes duplicate and the nuclkeus is clearly visible.

Prophase: Each chromosome has duplicated and now consists of two sister chromatics. The nuclear envelope breacks down into vesicles.


Metaphase: The chromosomes align at the equitorial plate and are held in place by microtubles attached to the mitotic spindle and to part of the centromere.


Anaphase: The chromosomes have separated.


Telephase: The cytoplasm is begining to separate.
