Interfascicular cambium develops from the cells of
medullary rays
xylem parenchyma
endodermis
pericycle
A.
medullary rays
In dicot stems, the cells of cambium present between primary xylem and primary phloem is the intrafasicular cambium. The cells of medullary rays, adjoining these intrafascicular cambium become meristematic and form the interfascicular cambium.
In dicot roots the innermost layer of the cortex is called endodermis. Next to endodermis lies a few layers of thick-walled parenchymatous cells called as pericycle.
Interfascicular cambium is a
primary meristematic tissue
primordial meristem
type of protoderm
secondary meristematic tissue
In the following pairs, where do you get lignin in both the element?
Tracheid and collenchyma
Sclerenchyma and sieve tube
Sclerenchyma and trachea
Parenchyma and endodermis
One of the characteristic of sieve tube is
it is a part of phloem
function is transport of inorganic solutes
it is dead cell
sieve plate is not present
Portion of apical meristem that gives xylem tissue is called
protoxylem
procambium
metaxylem
tracheid
Age of a tree can be estimated by
its height and girth
biomass
number of annual rings
diameter of its heartwood
