5.5 Mutlicellular Life Outline
Multicellular organisms depend on interactions among different cell types.
•
Tissues are groups of ______________________________________________________________________________.
•
Organs are groups of _________________________ that perform a specific or related function.
•
Organ systems are groups of _________________________________ that carry out similar functions to help maintain homeostasis.
Specialized cells perform specific functions.
•
Cells develop into their mature forms through the process of _______________________________________________.
•
Cells differ because different ______________________________________________________________________________.
•
A cell’s ____________________________ in an __________________________ helps determine how it will differentiate.
•
An early animal embryo generally takes the shape of _______________________________________________________..
•
The ball folds inwards forming an inner layer( ____________________) and outer layer of cells( _________________) and middle
layer that separates them ( ________________________)
•
Endoderm forms, _________________________________________________________________________________________.
•
Mesoderm forms ________________________________________________________________________________________.
•
Ectoderm forms ________________________________________________________________________________________
Stem cells are unique body cells.
•
•
Stem cells have the ability to
–
__________________________ and ___________________________ themselves for long periods of time
–
remain ________________________________________________
–
develop into a variety of ____________________________________________________________________
Stem cells are classified into three types based on ability to develop into differentiated cell types of different tissues.
•
____________________________, or growing into any other cell type
•
__________________________, or growing into any cell type but a ___________________________ cell
•
_____________________________________, or growing into cells of a closely related cell family
•
•
Stem cells come from adults and embryos.
•
Adult stem cells are partially _______________________ cells found in specialized cells of
_________________________________________________________________________________________________
•
They can be taken from patient, grown in _______________________ and put into patient with ___________________
•
This helps to avoid ______________________________________________________________________________.
•
Adult stem cells can be hard to _____________________________________________________________.
•
Adult stem cells may contain more ______________________________________________ than embryonic stem cells.
•
Once thought that adult stem cells were only _____________________________ ( ____________ stem cell could only
produce ______________________ cells)
•
____________________________________ can cause a multipotent adult stem cell to possibly give rise to a
___________________________________________
•
The use of embryonic stem cells raises ______________________________________________________
•
Embryonic stem cells come from ________________________________________________.
•
Taken from cluster of undifferentiated cells( __________________________________________________________.
•
Embryonic stem cells are __________________________________ and can be __________________________________
•
They can be used to form any of the __________________________ _____________________ in humans.
•
If used in a transplant, the risk is higher that the stem cells will be ______________________________________ .
•
There is also the potential for ESC to grow ________________________________________________
The use of stem cells offers many currently realized and potential benefits.
•
Stem cells are used to treat ___________________________________________________________________.
•
Stem cells may cure ___________________________________________________________________________.
•
Stem cells may revolutionize the __________________________________________________________________.
