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
Interfascicular cambium is a
primary meristematic tissue
primordial meristem
type of protoderm
secondary meristematic tissue
Portion of apical meristem that gives xylem tissue is called
protoxylem
procambium
metaxylem
tracheid
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.
Age of a tree can be estimated by
its height and girth
biomass
number of annual rings
diameter of its heartwood
Medullary rays are tissues made up of
phloem parenchyma
xylem parenchyma
sieve tube
sclerenchyma
