Meristems: aka embryonic tissue(the origin)
areas where the rapid new growth originates.
Types:
Apical:- root point(cap) and stem apex elongation.
these give rise to!(down arrow)
Primary Meristems.:- these cells undergo division before differentiation.(pro-cambium(forms the vascular cambium and it’s side tissues))(, ground cambium(makes pith and cortex filler cells))(, protoderm(makes the epidermis for the plant as well as leaf primordium; found also on top of apical meristem))
So, primary growth forms primary tissues forms primary plant body.”don’tchaknow”
Lateral:- increases girth of roots and stems and is what we call secondary growth. (vascular cambium)(cork cambium grows newer filler cells and inner dermis)(intercalary cambium grows nodes on plants)
DFW word of the day
Meristem - N:
The undifferentiated plant tissue from which new cells are formed, as that at the tip of a stem or root.
ETYMOLOGY:
