CELL DIVISION MITOSIS

MITOSIS Cell Division for Growth

Mitosis All the cells DNA is found in the cell nucleus in structures called chromosomes

When cells divide, the chromosomes appear, divide and separate Mitosis When cells divide, the chromosomes appear, divide and separate

Two new cells form with identical chromosomes to the original cell Mitosis Two new cells form with identical chromosomes to the original cell

Here are the main cell parts involved in mitosis- Centrioles Cell Membrane Nucleolus Chromatin network Nuclear Envelope

MITOSIS can be divided into FIVE different stages: Interphase Prophase Metaphase Anaphase Telophase

Remember the sequence IPMAT IInterphase PProphase MMetaphase AAnaphase TTelophase

DNA replication occurs MITOSIS – Interphase- This is the phase in between the cell dividing. DNA replication occurs

Chromosomes line up SINGLE FILE 7 MITOSIS – Metaphase - Chromosomes line up SINGLE FILE at the Equator

8 MITOSIS – Anaphase- Double stranded Chromosomes split to form TWO single stranded chromosomes

Single stranded chromosomes move to opposite poles 9 MITOSIS – Anaphase Single stranded chromosomes move to opposite poles

MITOSIS Original Cell Divides to form TWO new cells with the SAME number of chromosomes
