What can happen if mitosis is done without any regulation?
Mutations: tumors, cancer
100
What is the purpose of mitosis in multi-cellular organisms?
Cellular Growth and Repair
100
What is the function of the S stage during interphase?
The chromosomes are copied and duplicated to prepare for division.
100
What are some cells that don't undergo mitosis?
Heart muscle cells, nerve and brain cells,
200
What are the functions of the centrioles in mitosis?
They pull apart the chromosome pairs that are divided into two daughter cells.
200
At what rate do somatic cells divide?
Regulation of somatic cells is linked to your body's need for them. Some cells divide more than others and more cells need to divide if the body is still growing.

What is the purpose of mitosis in unicellular organisms
type of asexual reproduction
200
What happens in prophase and metaphase?
Prophase- chromosomes condense and nuclear membrane start to break apart
Metaphase- copied chromosomes align in middle of cell and the centrosomes are on opposite sides of the cell
200
What is it called when cancer cells spread to new parts of the body?
metastasis
300
What is the name of the daughter cell with half the number of chromosomes as the parent cell and are they products in MITOSIS
Haploid, no
300
Is cell division faster in adults or children?
Children, specifically embryos because the organs are still forming and growing
300
What happens when the cell gets too big?
It takes too long for nutrients and energy to travel along the cell membrane and get to the nucleus. Cell division starts
300
What happens in anaphase and telophase?
Anaphase- The chromosomes are pulled apart by the centrosomes into identical groups and move to opposite sides of the cell.
Telophase- Nuclear membrane starts to reform and cytokinesis starts to occur
300
What is the indention where the cell pinches together during cytokinesis before completely dividing
Cleavage furrow
400
What is the name given to a daughter cell the same number of chromosomes as the parent cell?
Diploid
400
True or False? The inner lining of your digestive tract receives a lot more damage than other organs. What does this cause?
True; cells divide more and are replaced every few days.
400
How does mitosis help maintain homeostasis in living things?
It repairs tissues, organs, body systems, and other important parts to keep the body healthy
400
What is the separation of the cytoplasm called?
Cytokinesis
400
True or False; Gametes can undergo mitosis as well as meiosis
False
500
What are the stages of mitosis in interphase before cell division?
G1, S, G2
500
What happens if damaged DNA is detected while undergoing the cell cycle?
The cycle stops and the cell attempts to repair or finish the DNA. This is crucial to prevent cancer cells.
500
What would happen if our cells couldn't undergo mitosis?
All of our cells would die causing all of our systems and organs to fail because the dying cells wouldn't be replaced with new cells.
500
How long does mitosis take in a typical human cell?
20-24 hrs.

What is the difference between binary fission and mitosis?
Binary fission mostly occur in prokaryotic cells while mitosis occurs in somatic cells in organisms.
