Ciliated epithelium lines the inner surface of fallopian tubes, bronchioles and small bronchi.
Squamous epithelium lines alveoli.

(171)Answer : (1)
Hint:
Transport of substances
Solution:
Blood is the fluid connective tissue of body. In all connective tissues except blood, the fibroblast cells secrete
fibres of structural proteins collagen or elastin.

Communication junctions (intercalated discs) at some fusion points allow the cells to contract as a unit, i.e.,
T0

when one cell receives a signal to contract, its neighbours are also stimulated to contract.

Hint:
Excitability is property of structural and functional cells of this tissue.
Solution:
Neural tissue present in CNS & PNS, controls the functions of the body. Cardiac muscles regulate heart
contraction and skeletal muscles cause movement of body parts.
(175)Answer : (2)
Hint:
Generation of action potentials requires characteristic of a tissue termed excitability.
Solution:
The excitable character of nervous tissue allows generation of nerve impulses that help in regulation of most
body tissues. The neuroglial cells constitute more than one-half the volume of nervous tissues of our body. The
property of division is shown by glial cells, so they can be responsible for tumors but neurons do not exhibit
that property.

(176)Answer : (2)
Solution:
If the columnar or cuboidal cells bear cilia on their free surface they form ciliated epithelium. Their function is to
move particles or mucus in a specific direction over the epithelium. They are mainly present in the inner
surface of hollow organs like bronchioles and fallopian tubes.

Solution:
Cartilage is solid and pliable and resist compression.

Bones have a hard and non-pliable ground substance, rich in calcium salts and collagen fibres which give
bone its strength.
(178)Answer : (1)
Solution:
Lamellae are absent in cartilage.
(179)Answer : (4)
Solution:
Ligament is a dense regular connective tissue.
(180)Answer : (3)
Hint:
Fluid connective tissue.
Solution:
Examples of loose connective tissues are areolar tissue and adipose tissue. Specialized connective tissue
include skeletal connective tissue like cartilage, bone and fluid connective tissue like blood and lymph. Muscle
tissue comprises muscles of body which enable movements of the body.

(181)Answer : (1)
Solution:
In tight junctions, the two adjacent cell membranes are fused together to stop substances from leaking across
the tissue.
(182)Answer : (3)
Hint:
Property to decrease in size is associated with muscular tissue.
Solution:
Property of excitability and conductivity is common to muscular and neural tissue.

Solution:
In unicellular organisms, all functions like digestion, respiration and reproduction are performed by a single
cell. Hydra, Scypha and Planaria are multicellular invertebrates.

Solution:
Abundant intercellular substance is present in connective tissue.

(188)Answer : (2)
Hint:
Squamous epithelium consists of thin, flattened and polygonal cells.
Solution:
Blood vessels facilitate diffusion of various molecules such as gases, so they must have thin walls which is a
feature of squamous epithelium. Squamous epithelium is present in endothelium of blood vessels, alveoli of
lungs etc., for the same reason that they can easily allow passage of molecules across them.
(189)Answer : (3)
Solution:
Mast cells produce histamine, heparin and serotonin.
(190)Answer : (4)
Solution:
Squamous epithelium forms the innermost wall of blood vessels (endothelium), air sac (alveoli) of the lungs.

(191)Answer : (2)

(192)Answer : (3)
Solution:
Areolar tissue is loose connective tissue.
(193)Answer : (2)
Solution:
The fibres of skeletal muscles are striated and multinucleated whereas cardiac muscles are uninucleated.
(194)Answer : (1)
Solution:
Cardiac muscle fibres are present in heart and are branched.
(195)Answer : (2)
Solution:
The squamous epithelium is made of a single thin layer of flattened cells with irregular boundaries.

(196)Answer : (2)
Solution:
In a typical muscle, such as the biceps, striated skeletal muscle fibres are bound from the outside by an elastic
but tough covering called sarcolemma.

(197)Answer : (4)
Solution:
Transport of nutrients is done by blood.
(198)Answer : (2)
Solution:
Muscle fibres are elongated cells of muscular tissue that require energy to bring about movement.

(199)Answer : (1)
Hint:
Cardiac muscles are striated and involuntary
Solution:
All smooth muscles are involuntary and unstriated but cardiac muscles are involunary and striated. Similarly,
all voluntary muscles are striated (skeletal muscles) but all striated muscles are not voluntary e.g. cardiac
muscles are striated and involuntary.
