Quiescent centre is found in plants at
root tip
cambium
shoot tip
leaf tip
A.
root tip
Quiescent centre is a region in the apical meristem of a root where cell division proceeds very slowly or not at all. Although, the cells are capable of resuming meristematic activity should tissue surrounding them to be damaged.
Portion of apical meristem that gives xylem tissue is called
protoxylem
procambium
metaxylem
tracheid
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
Age of a tree can be estimated by
its height and girth
biomass
number of annual rings
diameter of its heartwood
Interfascicular cambium is a
primary meristematic tissue
primordial meristem
type of protoderm
secondary meristematic tissue
Interfascicular cambium develops from the cells of
medullary rays
xylem parenchyma
endodermis
pericycle
