What is the definition of mitosis?
Mitosis is
cell division
producing two
identical
cells.
What type of cells does mitosis occur in?
Mitosis occurs in
body/somatic cells
.
What is maintained during
mitosis
regarding
chromosomes
?
Mitosis maintains the same chromosome number.
What are the stages of mitosis and their key events?
**
Interphase
**: Cell prepares for division.
**
Prophase
**: Chromosomes condense.
**
Metaphase
**: Chromosomes line up at the equator.
**
Anaphase
**: Chromosomes are pulled apart.
**
Telophase
**: New nuclear membranes form.
**
Cytokinesis
**: Cell splits into two.
What is the purpose of mitosis?
Mitosis is for
growth
,
repair
, and
replacement
.
What is the primary result of mitosis when a single cell divides?
Two identical daughter cells are produced.
Why are the daughter cells produced by mitosis identical?
They have the same number and type of
chromosomes
.
Compare mitosis and meiosis in terms of cell production.
Mitosis
: Produces identical cells, maintains
chromosome
number.
Meiosis
: Produces diverse
gametes
, reduces chromosome number by half.
What is the key characteristic regarding chromosome number during mitosis?
Each daughter cell has the same number of chromosomes as the
parent cell
.
If a cell with 30 chromosomes begins mitosis, how many chromosomes will it have at the end of Anaphase?
60
60
60
What is the function of the centromere during mitosis?
It holds
sister chromatids
together
What is the relationship between Anaphase and Cytokinesis?
Anaphase separates
chromatids
, Cytokinesis divides the cell
How does the process of mitosis relate to the overall life cycle of a cell?
Mitosis is crucial for
growth
, repair, and
reproduction
Why is it important for cells to maintain the same chromosome number after mitosis?
To ensure genetic stability across
generations
What happens to the chromosomes during Prophase?
Chromosomes
condense
and become visible
What is the significance of the stages of mitosis in cell division?
Each stage ensures accurate and equal division of
chromosomes
How does the behavior of chromosomes during Anaphase affect the outcome of cell division?
It ensures equal distribution of
genetic material
What is the role of
cytokinesis
in the
cell cycle
?
It divides the cytoplasm to form two cells
What happens to the chromosomes during the Interphase before mitosis?
DNA duplicates
, forming
sister chromatids
What is the final outcome of mitosis in terms of cell number?
Two identical
daughter cells
are formed
How does Anaphase ensure genetic consistency in daughter cells?
By separating
sister chromatids
into individual
chromosomes
What happens to the nuclear membrane during
Telophase
?
New nuclear membranes form around chromosomes
What is the role of Anaphase in ensuring accurate cell division?
It separates
sister chromatids
to ensure equal distribution
What is the significance of genetic consistency in mitosis?
Each
daughter cell
receives identical genetic material
What happens to chromosomes during Cytokinesis?
The cell divides into two
identical
cells
How many chromosomes does a human cell have before mitosis?
46
46
46
What role does mitosis play in tissue repair?
It generates new
identical
cells
What is the primary purpose of mitosis?
To create identical
daughter cells
What stage follows Anaphase in mitosis?
Telophase
What are the stages of mitosis in order?
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
What happens during cytokinesis?
The
cell
physically divides into two cells.
What is the role of sister chromatids during mitosis?
Sister chromatids separate during
Anaphase
.
What happens to sister chromatids during Anaphase?
They separate and move to
opposite
poles
If a cell has
30
30
30
chromosomes, how many individual chromosomes are present during Anaphase?
60
60
60
What is the role of mitosis in asexual reproduction?
It produces
identical
offspring
from a
single
parent
