What are meristems?
Meristems produce unspecialised cells that
are able to divide and form any cell type in
the plant ­ they act like embryonic stem
However, unlike human stem cells, these
cells can divide to generate any type of cell
for as long as the plant lives…read more

Cloning Plants
Cuttings taken from an area of the plant
that is growing will contain unspecialised
meristem cells which can differentiate to
make any cell
This means a whole new plant can grow
from the cutting
This new plant will be a clone of the
original/parent plant…read more

Why clone plants?
Gardeners often take cuttings from plants
with desirable characteristics, and then
plant them to produce identical copies of
the parent plant…read more
