What is cell differentiation?
Transformation of a
stem cell
into a
specialized
cell
Why are specialized cells important for the body?
They form different
organs
and tissues
What controls the specialization of stem cells?
Genes
control which specialized cell forms
Why is cell differentiation important for the body?
It allows different
body parts
to perform specific tasks
What does a specialized cell do?
Performs unique functions like
muscle
or
nerve
cells
What is a stem cell?
An
unspecialized
cell that can
divide
How can the process of differentiation be compared to career choices?
Like choosing a career path in
high school
What would happen without differentiation in the body?
Our bodies would be a mass of
identical
cells
What is the significance of the different chromosome arrangements during the stages of cell division?
They ensure the proper segregation of
genetic material
to the daughter cells
How does cell differentiation contribute to the overall function of an organism?
Enables
specialization
of cells
Supports complex body functions
Allows for diverse tissue types
What is the primary role of differentiation in development?
It creates
specialized
cells
Why is cell differentiation important in multicellular organisms?
It allows different
body parts
to have specific functions
What is the process by which multicellular organisms develop?
Cell differentiation
What is the difference between differentiation and growth in cells?
Differentiation: Cells change
type
and specialize
Growth: Cells increase size and number
What is the outcome of repeated divisions of stem cells?
Creation of
various cell types
What does growth involve in terms of cell characteristics?
Increasing
size
and
number
of cells
What is the primary function of blood cells?
Transport
oxygen
Where can skin cells be found?
On the
surface layer
of the body
How can differentiation be compared to a band?
Each member plays a
distinct
instrument
Allows the band to function together
Creates a harmonious outcome, like
specialized
cells in the body
What are the key differences between mitosis and meiosis?
Mitosis:
Single cell division
Produces 2
genetically
identical
daughter cells
Maintains
chromosome
number (2N)
Meiosis:
Two
successive
cell divisions
Produces 4 genetically
distinct
daughter cells
Reduces
chromosome number by
half
(from 2N to N)
How do blood cells function in the body?
They transport
oxygen
through
blood vessels
What do unspecialized stem cells develop into?
Specialized
cells
What roles do specialized cells serve in the body?
They have unique roles like
muscles
and
brain cells
What happens to a stem cell during differentiation?
It divides and specializes into different
cell types
What is the structure shown in the image?
Cell division
What type of cells do stem cells develop into during differentiation?
Specialized cells
What are the stages of differentiation?
Stem cell
: unspecialized cell
Committed precursor cell
: starts to specialize
Specialized cell
: like muscle or nerve cell
Why are both differentiation and growth necessary for complex organisms?
They
enable
proper
function
and
development
How does cell differentiation occur in multicellular organisms?
One
stem cell
divides into two identical
daughter cells
Daughter cells specialize differently
Repeated divisions create various cell types
What are the two important processes in cell development?
Differentiation
and
growth
What does differentiation involve in terms of cell function?
Changing
what a cell does
What is the significance of cell differentiation?
It builds complex
organisms
and enables specific tasks
What is the significance of having various cell types in the body?
It allows for
specialized functions
in different body parts
What type of cells are shown in the third image?
Bone cells
What is the function of bone cells?
They
provide
support
to
the
body
What type of cells are shown in the second image?
Surface
skin cells
What role do skin cells play in the body?
They provide
protection
as the surface layer
What type of cells are shown in the first image?
Blood cells
What is the role of specialized cells in multicellular organisms?
To perform
specific functions
Where are blood cells located?
In
blood vessels
