describe stem cells
undifferentiated
cells that divide by
mitosis
to produce more undifferentiated cells and
differentiate
into
different
types of cells
give types of animal stem cells
embryonic
and
adult
describe embryonic stem cells
come from early human
embryo
to differentiate into
most
types of cells
describe adult stem cells
come from adult
bone marrow
and differentiate into
certain types
of cells (
blood
cells)
give conditions treated by stem cells
diabetes
and
paralysis
give two medical uses of stem cells
faulty cell replacement and
therapeutic cloning
describe process of faulty cell replacement
extract
embryonic stem cells
stimulate
differentiation
replace
faulty
cells with
specialised
cell
describe process of therapeutic cloning
embryo produced with
same genetic material
as patient
embryonic stem cells
transplanted
to patient
embryonic stem cells
differentiate
inside patient
give disadvantages of stem cell treatment
limited
supply of embryonic stem cells, risk of
infection
, risk of
rejection
and
ethical
objections
give type of plant stem cell
meristem
describe meristem stem cell
found in growing
roots
and
shoots
to differentiate into
any
type of plant cell
give uses of meristem stem cells
produce
clones
of desired plants for particular
characteristic
or prevent
extinction
