Phases
The phase where the sister chromatids pull away from each other.
ANAPHASE
What happens during interphase?
During the Interphase the cell grows and makes a copy of its DNA
Why is mitosis important for cell division?
It is important because it is a way of making more cells that the same as the parent cells.
How is cytokinesis different from mitosis?
In cytokinesis, the cytoplasm splits. Mitosis is when the cell gets prepared to split.
The phase where chromatin condenses into chromosomes.
PROPHASE
How long does it last?
18-20 hours
How is mitosis different from meiosis?
Mitosis is cell division for the asexual reproduction of unicellular eukaryotic cells while Meiosis is the type of cell division for gametes in sexual reproduction.
True or False? Cytokinesis divides the nucleus.
FALSE
The phase where the cytoplasm is split.
CYTOKINESIS
What are three subphases? How are they different?
1. G1 - This is the longest stage and this is where the cell grows
2. Synthesis - this is where DNA is being copied.
3. G2 - Very similar to G1, makes sure the cell is ready to go through mitosis.
What are some factors that can cause errors in cell division?
- Interphase doesn't work properly and does not prepare the cell for mitosis.
- Failure to Kinect spindle fibers.
True or False? Cytokinesis comes after mitosis.
TRUE
The phase where the spindle fibers connect to the chromosomes at the centromeres.
METAPHASE
What happens when cells exit interphase?
It then enters Mitosis and can complete its division.
What is the role of spindle fibers in mitosis?
They are necessary to equally divide the chromosomes in a parental cell into two daughter cells during Mitosis.
What is the end result of cytokinesis?
Two daughter cells are made.
The phase where two nuclei form.
TELOPHASE
How does DNA replication occur during interphase and why is it necessary for mitosis to run smoothly?
The DNA is doubled and prepared when it goes through the phases which will allow it to split into two daughter cells.
What are the different stages of mitosis and what happens during each stage?
- Prophase - chromatin condenses into chromosomes
- Metaphase - Spindle fivers connect to the chromosomes at the centromeres.
- Anaphase - Sister chromatids pull away from each other.
- Telophase - Two nuclei form.
What is the difference in the cytokinesis stage in animals and plant cells.
- In plants, the division starts in the center of the cells and moves towards the cell walls
- In animals, the division starts at the edges of the cell and moves towards the center.
