What is the definition of mitosis?
Mitosis is cell division producing two identical cells
What are the phases of mitosis?
Prophase, Metaphase, Anaphase, Telophase
How does mitosis contribute to the replacement of old cells?
By producing new identical cells to replace them
How many daughter cells are produced in mitosis?
Two identical daughter cells
What is the main purpose of mitosis?
To ensure each daughter cell receives identical chromosomes
How does mitosis differ from meiosis in terms of chromosome number?
Mitosis maintains the original chromosome number
What mnemonic can help remember the order of mitosis phases?
PMAT
What is the purpose of mitosis in the body?
To grow bigger and fix injuries
What is mitosis compared to in the explanation?
Making copies of toys
What is the outcome of mitosis?
More cells that are just like them
Why is mitosis important for living organisms?
It allows growth and healing
How do chromosomes behave during mitosis?
They line up and then split apart
What are the steps of mitosis?
Prophase
Metaphase
Anaphase
Telophase
What happens after chromosomes split during mitosis?
Two new rooms are built for them
How many phases are there in mitosis?
Four phases
What are the key events in telophase of mitosis?
Nuclear envelopes reform around each set of chromosomes
Cytokinesis occurs, dividing the cytoplasm
How does mitosis differ from meiosis?
Mitosis creates identical cells, meiosis creates diverse cells
What are the key events in anaphase of mitosis?
Sister chromatids separate
Chromosomes move to opposite poles
What happens to the nuclear envelope during prophase?
It breaks down
Why are the phases of mitosis important?
They ensure complete genetic material distribution
What are the key events in prophase of mitosis?
DNA condenses into chromosomes
Nuclear envelope breaks down
Spindle fibers begin to form
What are the key functions of each step in mitosis?
Prophase: DNA condenses, spindle fibers form
Metaphase: Chromosomes align at the cell's center
Anaphase: Chromosomes separate and move to poles
Telophase: New nuclear membranes form around each set
What reforms around each set of chromosomes during telophase?
Nuclear envelopes
What happens to sister chromatids during anaphase?
They separate
How can the steps of mitosis be remembered easily?
Using the phrase "Please Make Another Toy"
What are the key differences between mitosis and meiosis?
Mitosis:
Produces 2 cells
Chromosome number: Same
Purpose: Growth and repair
Meiosis:
Produces 4 cells
Chromosome number: Half
Purpose: Reproduction
How does mitosis contribute to growth?
It increases the number of cells
What forms during prophase of mitosis?
Spindle fibers
Why is mitosis important for body tissues?
It allows for growth and repair of tissues
What occurs during cytokinesis?
Division of the cytoplasm
What role does mitosis play in repair?
It replaces damaged or lost cells
What is the main purpose of mitosis?
Growth and repair by creating identical cells
What is the difference between mitosis and meiosis?
Mitosis maintains chromosome number, meiosis reduces it
What is the primary function of mitosis?
To create two identical daughter cells
How does cytokinesis differ from mitosis?
Cytokinesis divides the cytoplasm, mitosis divides the nucleus
What is the role of spindle fibers in mitosis?
They attach to centromeres and help separate chromosomes
What does mitosis ensure about genetic information in daughter cells?
Each cell has the same genetic information
What are the key functions of mitosis?
Growth: Increases cell number for tissue development
Repair: Replaces damaged or lost cells
Asexual Reproduction: Enables reproduction without a partner
What happens during each phase of mitosis?
Prophase: DNA starts to condense.
Metaphase: Chromosomes line up in the middle.
Anaphase: Chromosomes split and move apart.
Telophase: New nuclei form around separated chromosomes.
What happens to the DNA during mitosis?
It gets ready for cell division
