cell specialization Flashcards
multicellular organisim
collection of different types of cells doing different jobs
cell specialization
cells developing differently to perform particular functions
during development what happens in cells
genes turn off that aren’t needed for the cells particular task
stem cell
unspecialized cell
every cell starts off as
stem cell
stem cells form specialized cells when
exposed to the proper environmental conditions
when stem cells remain unspecialized what happens to them
the actively divide for long periods
stem cells are capable of being used to treat injury and diseases why?
it is possible for them to become any type of cell
embryonic stem cells
found in embryos and will eventually undergo differentiation to perform different functions
embryos can be used from
umbilical cords or placentas
(to collect large amounts you must destroy the embryo (ethical tissues)
adult stem cells can be found?
blood, skin, + neutral, tissue (where tissues need to be replaced due to damage)
adult stem cells from one organ can be used to regenerate
another organ
tissue come together to form
organs
organs come together
organ systems
cells come together to form
tissues
regeneration
process whereby a body part is replaced or re-growth
