Paper Plate Mitosis


Mitosis is the stage of the cell cycle where the cell divides. Mitosis is used by multicellular organisms to grow or replace damaged cells. This paper plate mitosis activity uses pipe cleaners to show the stages of mitosis.

The key thing to remember about mitosis is that it produces two new daughter cells from one parent cell. Each daughter cell is genetically identical to the parent cell.

Mitosis is different to Meiosis where each new cell is not identical to the parent cell and only has half the number of chromosomes of a normal cell.

We used pipe cleaners and paper plates to demonstrate mitosis in a very basic way!

Interphase

This is when a cell is getting ready to divide. It increases the number of subcellular structures ( mitochondria, ribosomes etc), duplicates its DNA and forms chromosomes.

A chromosome has two arms, the left has the same DNA as the right.

Each arm is called a chromatid.

Mitosis

When a DNA has copied it’s contents and DNA it can go through the process of mitosis to divide.

Prophase

Chromosomes condense to become shorter, the membrane around the nucleus breaks down leaving the chromosomes free in the cytoplasm.

Metaphase

Chromsomes line up in the middle of the cell.

Anaphase

Spindle fibres form and pull the chromosomes apart. One chromatid from each chromosome moves to each end of the cell.

Telophase

Membranes form around each set of chromosomes. Each new cell now has it’s own nucleus.

Finally the cytoplasm and cell membrane divide to give two separate new cells. This is cytokinesis.

Mitosis – Quick Facts

Mitosis is where one cell divides into two genetically identical cells.

Mitosis occurs mostly for growth and replacement of damaged cells.

Mitosis is part of the cell cycle and usually divided into 5 stages.
