Both A and C

B
Both B and D

C
Both A and D

D

Solution

Starfish or sea stars are star-shaped echinoderms. Jellyfish are invertebrates belonging to the phylum Cnidaria. Flying fish is also called exocoetus. It is a marine fish. The cowfish is also called the horned boxfish and is recognisable by its long horns that protrude from the front of its head.
Question 2

D. Star fish - tubefeet

A
'A' and 'B'

B
'B' and 'C'

C
'C' and 'D'

D
'A' and 'D'

Solution

Cilia are the primary locomotary organs of paramecium which are covered throughout their body. Euglena have flagella and they move by beating up the flagella. Flagella are long, thin structures resembling a whip or a tail.
Question 3
1 / -0

Which of the following is the odd one?

A
Planaria

B
Liver fluke

C
Tapeworm

D
Ascaris

Solution

Planaria, tapeworm and liverfluke are all flatworms, whereas ascaris is a roundworm.
Question 4
1 / -0

Which of the following are sensitive to sulphur dioxide?

A
Algae

B
Lichens

C
Mosses

D
Ferns

Solution

Air pollutants dissolved in rainwater, especially sulphur dioxide, can damage lichens, and prevent them from growing. This makes lichens natural indicators of air pollution.
Question 5
1 / -0

Choose the group that contains fungi only.

A
Euglena, lichen

B
Yeast, mushroom

C
Anabaena, Amoeba

D
Paramecium, mycoplasma

Solution

Yeasts are eukaryotic, single-celled micro-organisms classified as members of the kingdom Fungi. A mushroom is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source.
Question 6
1 / -0

Which special structures are connected with wall of the lungs in class Aves?

A
Air Sac

B
Diaphragm

C
Spongy bones

D
Booklungs

Solution

An air sac is an extension of a bird's lung cavity into a bone or other part of the body. The air sac permits a unidirectional flow of air through the lungs.
Question 7
1 / -0

In Whittaker's classification, unicellular organisms are grouped under which of the following?

A
Kingdom Protists

B
Kingdom Fungi

C
Kingdom Monera

D
Kingdom Plantae

Solution

Monera is the taxonomic kingdom that includes prokaryotic organisms, which are organisms with cells that do not have a nucleus. Monera breaks down into four bacterial subcategories: archaebacteria, actinomycetes, mycoplasms and eubacteria.
Question 8
1 / -0

Bones of birds are

A
spongy and light

B
spongy and heavy

C
solid and heavy

D
solid and light

Solution

Spongy bones have honeycomb-like pockets, called trabeculae. In birds, these trabeculae widen to become air sacs. This makes the bones light and helps in flight.
Question 9
1 / -0

What is the major characteristic of phylum Annelida?

A
Flame cells

B
Metameric segmentation

C
Tentacles

D
Radial symmetry

Solution

Metamerism is the phenomenon of having series of body segments similar in structure, though some of them perform special functions. The body is divided into a series of segments, both externally and internally. Each segment is called a metamere and the segmentation is called metameric segmentation.
Question 10
1 / -0

Which of the following statement(s) is/are incorrect?

(i) Animals of phylum Coelenterata have a body made of two layers of cells.
(ii) Animals of phylum Coelenterata have a bilaterally symmetrical body.
(iii) Some of the animals of species Coelenterata live in colonies, while others have a solitary lifespan.

A
(i) only

B
(ii) only

C
(i) and (ii)

D
(i) and (iii)

Solution

All coelenterates are aquatic, mostly marine. The bodyform is radially symmetrical, diploblastic and does not have a coelom. The body has a single opening, the hypostome, surrounded by sensory tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey. These tentacles are surrounded by a spacious cavity called the gastrovascular cavity or coelenteron. Hence, statement (ii) is incorrect.
Question 11
1 / -0

Which of the following is a common characteristic of flatworms and roundworms?

A
Triploblastic

B
Acoelomate

C
Pseudocoelomate

D
Cellular level of organisation

Solution

The body of flatworms and roundworms is made up of three germ layers. There are three layers of cells from which differentiated tissues can be made, which is why such animals are called triploblastic.
Question 12
1 / -0

The cell wall of fungus is made up of

A
chitin

B
cellulose

C
peptidoglycan

D
pectin

Solution

The cell wall of fungi is made up of a complex polysaccharide (called chitin) that is present in the exoskeleton of most arthropods and cell wall of fungi.
Question 13
1 / -0

What is the correct identification of the following specimen?

A
Moss

B
Agaricus

C
Spirogyra

D
Fern

Solution

Agaricus has a circular and umbrella-like body. Agaricus is a genus of mushroom consisting of both edible and poisonous species. This genus includes common (button) mushroom and field mushroom.
Question 14
1 / -0

Which of the following characteristics is similar in both monerans and fungi?

A
Structure of fruiting body

B
Absorptive heterotrophy

C
Cellular structure

D
Mycelium

Solution

Absorptive heterotrophy is the mode of nutrition in which an organism secretes enzymes externally into the environment to digest organic materials, which are then absorbed.
Example: Fungi, some protists and monerans
Question 15
1 / -0

Which of the following statements is/are FALSE?

a. For plants, scientific names are based on agreed principles and criteria which are provided in the International Code for Botanical Nomenclature.
b. The scientific names ensure that each organism has only one name and that such a name has not been used for any other known organism.
c. In the scientific name Mangifera indica, 'Mangifera' represents a particular species, while 'indica' represents a genus.

A
Only a

B
Both a and b

C
Only b

D
Only c

Solution

This is the correct option as this statement is false. In the scientific name Mangifera indica, 'Mangifera' represents a particular genus while 'indica' represents a species.
Question 16
1 / -0

Which of the following options is NOT a characteristic of a vertebrate body?

A
Asymmetrical

B
Triploblastic

C
Coelomic

D
Presence of spinal cord

Solution

Vertebrates are bilaterally symmetrical. The left and the right halves of the body have the same design.

Question 17

1 / -0

Match the following.

a. Kingdom Monera	1. Unicellular eukaryotic organisms
b. Kingdom Protista	2. Eukaryotic multicellular organisms
c. Kingdom Fungi	3. Prokaryotic bacteria and blue-green algae

a - 3, b - 1, c - 2

a - 3, b - 2, c - 1

a - 1, b - 2, c - 3

a - 1, b - 3, c - 2

Solution

Kingdom Monera consists of prokaryotic bacteria and blue-green algae. Kingdom Protista consists of unicellular eukaryotic organisms. Kingdom Fungi consists of eukaryotic multicellular organisms.

Question 18
1 / -0

Which of the following is an egg–laying mammal?

A
Kangaroo

B
Bat

C
Platypus

D
Rat

Solution

Most mammals (e.g. bat, rat, human, cat) produce live young ones. However, a few of them, like the platypus and the echidna, lay eggs, and some, like kangaroos, give birth to very poorly developed young ones.
Question 19
1 / -0

How many chambers are present in a Piscean heart?

A
1

B
2

C
3

D
4

Solution

The number of chambers in the heart depends on the complexity of the body organization. For example, mammals are more complex and therefore, they possess maximum number of chambers in the heart (four-chambered heart) and fishes have less complex body organization than mammals, so they possess less number of chambers in the heart than found in case of mammals.
Piscean are fishes. They are exclusively water animals. Their skin is covered with scales/plates. They obtain oxygen dissolved in water by using gills. They are cold-blooded and have two-chambered heart.
Question 20
1 / -0

The peculiar water-driven tube system is found in

A
poriferans

B
coelenterates

C
echinoderms

D
molluscs

Solution

In Greek, 'echinos' means 'hedgehog' (skin is not smooth but is rough with spines) and 'derma' means 'skin'. Thus, these are organisms with spines on the skin. These are free-living marine animals. They have peculiar water-driven tube system which they use for moving around in water, capture and transport of food and respiration (exchange of gases). For example, starfish and sea urchins.
