Meristems are
plant tissue
Meristems are found in
plant tissue
of areas that are still
growing
Meristems
produce cells that can
differentiate
into any cell type
Meristems act like embryonic
cells
Meristems
can divide and differentiate into any
cell
type for aslong as it lives
Root hair cell has hairs to increase
surface area
of roots to absorb more
water
Stem cells are found in early stage embryos and can differentiate into any cell
Stem cells are crucial for
growth
,
repair
and development in organisms
Adult stem cells are only found in certain places:
bone marrow
Adult cells aren’t as
versatile
and
can’t
produce any type of cell, only certain ones
Stem cells can be used to make new
blood cells
or
skin cells
Stem cells
can be used in medicine to treat
paralysis
Stem cells can be used in medicine to cure
sickle cell ammonia
with
bone marrow
transplant to produce red blood cells
Risks of stem cells:
tumour
development due to
uncontrollable
cell division
If transported
stem
cells are not grown using the patient, the body may recognise it as a a foreigner and trigger
immune system
to attack.
In stem cells,
virus
can live inside of stem cell and then infect patient to make them even more
ill
People have ethical issues with
stem cells
and believe embryos shouldnt be used as it is a
waste
of a potential life.
a cell that is not already a specialised cell
a stemcell cannot change and then change again
