Section 1 - Specialised Cells and Stem Cells Flashcards
(11 cards)
What are red blood cells specialised for
carrying oxygen from the lungs to the body’s tissues
What are white blood cells specialise for
defending the body against diseases
Cell differentation
the process which a cell changes to become specialised for its job
How do cells change
they develop different organelles into different types of cells
This allows them to carry out specific function
Undifferentiated cells
stems cells that can divide to produce more undifferentiated
They can differentiated into different type of cells
Where are stem cell found more in
early human embryos
One adventage for using stem cells to cure disease
stem cells transferred from the bone marrow of a healthy person to replace faulty cells in sick people
One risk of using stem cells to cure diseases
stem cells frown in the lab mat be contaminated with a virus which could be passed on to a patient making them sicker
arguements for stem cell research
Curing suffering patients is more important than the right of embryos
Embryos used in research are often unwanted ones from fertility clinics which would be destroyed
arguements against stem cell research
human embryos shouldn’t be used for experiments since each one is a human life or has the potential to be one
Scientists should find and develop more other sources so people could be helped without using embryos
Explain how adults stem cells are different to embryonic stem cells
Adult stem cells can not turn into any type of cells, only certain ones
