Animals Exam Questions Fully Solved.
In multicellular animals, a group of similar cells alongwith
intercellular substances perform a specific function. Such an organisation is called _________. -
Answer tissue
The structure of the cells vary according to their function. Therefore, the tissues are different
and are broadly classified into four types namely, - Answer (i) Epithelial,
(ii) Connective
(iii) Muscular
(iv) Neural
We commonly refer to an epithelial tissue as _________ - Answer epithelium
___________________ is composed of a single layer of cells and functions as a lining for body
cavities, ducts, and tubes. The
compound epithelium consists of two or more cell layers and has protective function as it does
in our skin. - Answer Simple epithelium
On the basis of structural modification of the cells, simple epithelium is further divided into
three types namely, - Answer i) Squamous,
(ii) Cuboidal
(iii) Columnar
The _______ epithelium is made of a single thin layer of flattened
cells with irregular boundaries. They are found in the walls of blood vessels and air sacs of lungs
and are involved in functions like forming a diffusion boundary. - Answer squamous
The ___________ epithelium is composed of a single layer of
cube-like cells. This is commonly found in ducts of glands and tubular parts of nephrons in
kidneys and its main functions are secretion and absorption. The epithelium of proximal
convoluted tubule (PCT) of nephron in the kidney has microvilli. - Answer cuboidal
, composed of a single layer of tall and slender cells. Their nuclei are located at the base. Free
surface may have microvilli. They are found in the lining of stomach and intestine and help in
secretion and absorption - Answer columnar
If the columnar or cuboidal cells bear cilia on their free surface they are called
_________ epithelium - Answer ciliated
The function of ______ 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. - Answer ciliated
epithelium
Some of the columnar or cuboidal cells get specialised for secretion and are called
______________ - Answer glandular epithelium
isolated glandular cells found in - Answer alimentary canal
and multicellular glandular epithelium, consisting of cluster of cells found in - Answer salivary
gland
Exocrine
glands secrete - Answer mucus, saliva, earwax, oil,
milk, digestive enzymes and other cell products
___________ glands do not have ducts - Answer endocrine
The products of _______ glands called hormones are secreted directly into the fluid bathing the
gland. - Answer endocrine
________ epithelium is made of more than one layer (multi-layered) of cells and thus
has a limited role in secretion and absorption - Answer Compound
The main function is _______ is to provide protection against chemical and mechanical
