What happens in interphase? |
The cell grows then prepares for cell division by duplicating its genetic material. It's also the longest stage in the cell cycle |
|
|
What happens in prophase? |
The individual chromosomes pair up into x shaped chromosomes and the nuclear membrane begins to break down. Then the spindle fibres begin to form and start to pull to opposite poles of the cell. |
|
|
What happens in metaphase? |
The spindle fibres pull the x shaped chromosomes into a single line across the equator of the cell |
|
|
What happens in anaphase |
The spindle fibres begin to shorten then the x shaped chromosomes pull apart and moves the individual chromatids to opposite poles of the cell |
|
|
What happens in telophase |
This is the final stage in the cell cycle. One complete set of chromosomes is now at each pole of the cell. The spindle fibres also breakdown and a nuclear membrane forms around each set of chromosomes. They also separate completely |
|
|
What are the stages of mitosis |
-interphase -prophase -metaphase -anaphase -telophase |
|
|
What are the three phases of interphase |
-growth - preparation -replication |
|
|
What happens in early prophase |
-The replicated chromosomes pair up into x shaped chromosomes -the nuclear membrane begins to breakdown -spindle fibres begin to form - they begin to stretch across to opposite poles |
|
|
What happens in late prophase |
The spindle fibres finish forming and attach to the x shaped chromosomes at a point called the centromere and the nuclear membrane breaks down completely |
|
|
What happens in cytokinesis |
-the final stage of the cell cycle -in this stage the one cell containing two nuclei separate into two daughter cells -the new cells r identical to the original parent cell |
|
|
What is mitosis |
Mitosis is the processes in which the contents of the cells nucleus divide which produces to identical daughter nuclei |
|
|
What are some organelles that take place in cell division |
-DNA -Spindle Fibres -Chromosomes -Nuclei -Centrioles |
|
|
Daughter cells form from what ?? |
The parent cell |
|
|
Understand the cell cycle |
-growth and preparation - DNA replication -continued growth and preparation - Mitosis - cytokinesis |
