which type of cell is usually present in cortex

parenchyma

which type of cell is usually present in pith

parenchyma

which type of cell is usually present in medullary rays

parenchyma

In leaves, the ground tissue consists of thin-walled chloroplast containing
cells and is called

mesophyll

which type of plants has cambium is present between phloem and xylem

dicots

vascular bundle having cambium b/w phloem and xylem, this type of vascular bundle is called

open vascular bundle

type of vascular bundle

conjoint closed

type of vascular bundle

conjoint open

When xylem and phloem within a vascular bundle are arranged in an alternate
manner along the different radii, the arrangement is called

radial

the xylem and phloem are jointly situated along the same radius of vascular bundles

conjoint

radial vascular bundle is seen in

roots

conjoint vascular bundle is seen in

stems and leaves

The cortex of dicot roots consists several layers of thin-walled_____

parenchyma

The innermost layer of the cortex of dicot root is called

endodermis

The tangential as well as radial walls of the endodermal cells of the dicot root have a deposition of water-impermeable, waxy material suberin in the form of

casparian strip

thick-walled parenchymatous cells of dicot root referred to as

pericycle

Initiation of lateral roots and vascular cambium during the secondary growth takes place in which layer of dicot root

pericyle

The parenchymatous cells which lie between the xylem and the phloem of dicot root are called

conjuctive tissue

presence of two to four xylem and phloem patches is seen in

dicot root

All tissues on the innerside of the endodermis such as pericycle, vascular bundles and pith of dicot root constitute the

stele

Presence of polyarch xylem bundles is the characteristic of

monocot root

Pith is large and well developed in

monocot root

pith is inconspicuous in

dicot root

The outer hypodermis of dicot stem, consists of a few layers of

collenchyma cells

cortical cells of dicot stem consists of

parenchyma cells

which layer of dicot stem is rich in starch grains

endodermis

present on the inner side of the endodermis of dicot stem and above the phloem in the form of semi-lunar patches

pericycle

pericycle is formed of

sclerenchyma

In between the vascular bundles of dicot stem there are a few layers of radially placed parenchymatous cells, which constitute

medullary rays

the cross section of ____ shows the ring arrangement of vascular bundles

dicot stem

dicot stem has

endarch protoxylem

dicot root has

exarch protoxylem

A large number of rounded, parenchymatous cells with large intercellular
spaces which occupy the central portion of the dicot stem constitute the

pith

hypodermis of monocot stem has

sclerenchyma

Palisade parenchyma is present on

adaxial surface

Peripheral vascular bundles are generally smaller than the centrally located ones seen in

monocot stem

Spongy parenchyma is present

abaxial surface

The vascular bundles of dicot leaf are surrounded by a layer of thick walled

bundle sheath cells

certain adaxial epidermal cells along the veins modify themselves into large, empty, colourless cells

bulliform cells
