Lymphoid tissue consists of spleen, tonsils, lymph
nodes, thymus gland, Peyer’s patches, liver, etc.

in the body. Lymphoid tissue share responsibility
with myeloid tissue (red bone marrow) for
producing agranular leucocytes.

Earthworm is a reddish-brown terrestrial
invertebrate that lives in the moist soil, rich in
humus. They are soft and naked, hence cannot
survive in the dry earth. Therefore, they lives in

take all the types of animals and vegetable foods
197 (a)
Epithelial tissue has free surfaces, which faces
either a body fluid or the outside environment
and thus, provides a covering or a lining for some
part of body. It is found on a lining of small
intestine and helps in secretion and absorption
198 (d)
Both white and red muscle fibres have myoglobin.
Myoglobin contains heme group which is
responsible for carrying of oxygen molecules to
muscle tissues.

present in connective tissue. These cells secrete
histamine (vasodilator), serotonin
(vasoconstrictor), heparin (anticoagulant). White
and yellow fibres are present in matrix of

on the ventro-lateral sides of the intersegmental
grooves, i.e., 5th to 9th segments, i.e., 5/6, 6/7,
7/8 and 8/9 segment. They leads into
spermathecae and serves to receive the sperms
from another worms during copulation
204 (d)
The skin of the frog is naked (without scales),
smooth and slippery. It consists of two regions
epidermis and dermis. Dermis contains sac-like
mucous glands that discharges slimy mucous
205 (d)
Epithelium cells of the intestine involved in food
absorption have microvilli on their surface to
increase surface area for food absorption.
206 (d)
In frog, heart is a muscular structure situated in
the upper part of the body cavity. It has three
chambers, two atria and one ventricle. As
ventricle is incompletely divided hence mixing of
oxygenated and deoxygenated blood is visible in
this heart. That’s why it is also called mixed circuit
heart
207 (d)
Earthworm’s intestine starts from the 15th
segment and continues till the last segment. A pair
of short conical intestinal caecae projects from the
intestine on the 26th segment

excretory and reproductive ducts. The undigested
solid waste moves into the rectum and passes out
through cloaca
212 (c)
A small spherical gall bladder lies between the
two main lobes of the liver. It stores bile secreted
by the liver before releasing into the duodenum
213 (b)

214 (d)
The thorax of a cockroach forms the middle part
of the body. It consists of three segments the
anterior prothorax, middle mesothorax, last
metathorax
215 (b)
Lymphocyte is not phagocytic in nature. They
produce antibodies as they are the key cells of
immune system.

A-Dendrites; B-Cyton; C-Axon
217 (a)
Alimentary canal
218 (b)
Thin Malpighian tubules in cockroaches are
present at the junction of mid gut and hind gut.
These tubules have excretory role
219 (a)
Blood vascular system of the cockroach is of open
type. Blood vessels are poorly developed and
opens into the haemocoel
220 (c)
The type of epithelial cells that line the inner
surface of fallopian tubes, bronchioles and small
bronchi, are known as ciliated epithelium.
221 (b)
White blood cells (leucocytes) are of two types :

Page| 46

Granulocyte : This types of WBC, have
granules in cytoplasm. These are
eosinophils, basophils and neutrophils.
Agranulocytes : This types of WBC, does
not have granules in cytoplasm, e.g.,
lymphocytes and monocytes.
222 (c)
Smooth muscles are called smooth, plain, non
striated involuntary or unstriped muscles due to
absence of striations. These nuscles occur in the
wall of hollow internal organs (alimentary canal,
gall bladder, bile ducts, etc.); in capsules of lymph
glands, spleen etc; in iris and ciliary body of eyes
etc. there is no connection of these muscles with
bones.
223 (b)
Spleen or blood bank is the largest mass of
lymphoid tissue present on the left side against
the stomach of jawed vertebrates. It acts as the
reservoir of important lymphocytes and plasma
cell reservoir and as a store house of RBCS
225 (c)
A pair of male genital pores are present on the
ventro-lateral sides of the 18th segment. They
serves for the exit of the sperms
226 (a)
In cockroach, fertilised eggs are stored in the dark
reddish to blackish brown capsule, (about 3/8II
(8 mm long) called oothecae. On an average,
females produces 9-10 oothecae, each containing
14-16 eggs
227 (a)
Excretory system of a frog consists of a pair of
kidneys, ureters, urinary bladder and cloaca
228 (c)
Monocyte is the largest WBC, which involves in
phagocytosis of pathogen like bacteria.
229 (c)
Gizzard is a muscular oval sac in segment 8-9 of
the earthworm. It helps in grinding the soil
particles and decaying leaves which earthworm
eats
230 (c)
Connective tissues are classified into three types
loose connective tissue, dense connective tissue
and specialised connective tissue
231 (d)
All the statements are correct
232 (c)
In females, the 7th sternum is boat-shaped and
together with 8th and 9th sterna it forms a genital
pouch whose anterior part contains it female
gonopore, spermathecal pores and collateral
glands
233 (d)
Loose connective tissue, also called areolar
connective tissue, is the ‘packing material’ of the
body that anchors blood vessels, nerves and body
organs. It contains fibroblasts that synthesize the
fibres and ground substance of connective tissue
and wandering macrophages that phagocytize
pathogens or damaged cells. The different fibres
types include strong collagen fibres and thin
elastic fibres formed of the protein elastin.
234 (b)
Earthworm is ureotelic animal. Their excretory
matter is mainly urea. Their discharge of waste
matter via gut is an adaptation to conserve water
by its reabsorption in the gut
235 (a)
Ommatidia of cockroach is the visual unit. Each
eye consists of about 2000 hexagonal ommatidia
with the help of which, a cockroach can receives
several images of an object
236 (c)
Integumentary nephridia are attached to the
inner surface of the body wall in all the segments
except the first two. They discharge waste matter
to the exterior by nephridiopores. Therefore, they
are responsible for the exonephric excretion
237 (b)
Morphology refers to the study of externally
visible features, i.e., shape, size, colour, symmetry
238 (c)
The midbrain of the frog is characterised by a pair
of optic lobes in it
239 (b)
Earthworm is also known as ‘friends of farmers’
because they make burrows in the soil and make
it porous which helps in the respiration and
penetration of developing plant roots. The
process of increasing fertility of the soil by
earthworm is called vermicomposting
240 (c)
The skin of frog is smooth and slippery due to the
presence of mucous not of gelatinous sheath

242 (d)
Haversian canal is one of many channels formed
within bone by the development of osteoblasts in
concentric rings around them and whose function
is to facilitate the linking of the living parts. Each
canal may contain an artery, a vein and a nerve
and the canals ramify throughout the bone
communicating with the bone marrow and the
periosteum.
243 (a)
The columnar epithelium is composed of a single
layer of tall and slender cells. If the columnar cells
bear cilia on their free surface they are called
ciliated columnar epithelium. They are mainly
present in the inner surface of hollow organs like
bronchioles, oviduct and fallopian tubes. Their
function is to move particles or mucus in a
specific direction over the epithelium.
