Question 1
4 / -1

Dachigam wildlife sanctuary in Kashmir is associated with

A

Cervus elaphushanglu

B
Rhinoceros

C
Macaca silenus

D
Indri indri

Solution

The Kashmir stag (Cervus elaphus hanglu), also called hangul, is a sub-species of Red Deer. In Kashmir, it is found in Dachigam National Park at elevations of 3,035 meters.
Question 2
4 / -1

Match column I with column II

Column I

a) Pyrolysis

b) Carbon monoxide

c) Blue baby syndrome

d) Black foot syndrome

Column II

(i) Methemoglobinemia

(ii) chronic exposure to arsenic

(iii) asphyxia and giddiness

(iv) Disposal of hospital- waste

A
a(iv), b(iii), c(i), d(ii)

B
a(iv), b(i), c(ii), d(iii)

C
a(iii), b(iv), c(i), d(ii)

D
a(i), b(iii), c(iv), d(ii)

Solution

Pyrolysis is a thermochemical decomposition of organic wastes. Hospital waste is usually decomposed by this method. Carbon monoxide causes asphyxia (deficient oxygen supply to the body) and giddiness. Blue baby syndrome is caused by Methemoglobinemia (Methemoglobin is the haemoglobin containing Fe ³⁺instead of normal Fe ²⁺). Due to chronic exposure to arsenic, the skin become darker and forms black colour pustules leading to black foot syndrome.
Question 3
4 / -1

The sequencing in DNA and chemical nature of proteins have been used as the basis of classification by

A
Alpha-taxonomist

B
Chemo-taxonomist

C
Karyo-taxonomist

D
Cytotaxonomist

Solution

Chemo-taxonomy is a basis of classification used by chemo-taxonomist which is based on sequencing in DNA, chemical nature of proteins and similarities in structure of certain compounds among the organisms that are being classified.
Question 4
4 / -1

Who proposed the natural system of classification?

A
Carolus Linnaeus

B
Julian Huxley

C
Engler & Prantl

D
Bentham & Hooker

Solution

Bentham and hooker gave natural system of classification. The gymnosperms were given an equal rank to dicotyledons and monocotyledons in this classification.
Question 5
4 / -1

In which group of organisms the Cell walls form two thin overlapping shells which fit together?

A
Chrysophytes

B
Euglenoids

C
Dinoflagellates

D
Slime moulds

Solution

Chrysophytes are a group of protists which includes diatoms and golden algae. A special character of diatoms is that, the cell walls form two thin overlapping shells that fit together like a soap box. Their cell walls are embedded with silica and hence, are indestructible.
Question 6
4 / -1

Isogamous condition with non-flagellated gametes is found in

A
Spirogyra

B
Volvox

C
Fucus

D
Chlamydomonas

Solution

Algae reproduce by vegetative, asexual and sexual methods. Sexual reproduction takes place through fusion of two gametes. These gametes can be flagellated and similar in size (as in Chlamydomonas) or non-flagellated (non-motile) but similar in size (as in Spirogyra). Such reproduction is called isogamous. Fusion between one large, non-motile (static) female gamete and a smaller, motile male gamete is termed oogamous, e.g., Volvox, Fucus.
Question 7
4 / -1

In Selaginella life cycle, generative tissue of female gametophyte makes

A
archegonia

B
diaphragm

C
prothallial cell diaphragm

D
androgonial cells

Solution

Archegonia originate in the apical region of the female gametophyte. A single superficial cell of female gametophyte develops an archegonium.
Question 8
4 / -1

Type of venation in fern leaves is

A
furcate

B
parallel

C
unicostate

D
reticulate

Solution

Venation in fern leaves is furcate. The veins divide in a forked manner and never come back together i.e. unite again.
Question 9
4 / -1

Which amongst the following are Vascular cryptogams?

A
Gymnosperm

B
Angiosperm

C
Bryophyte

D
Pteridophyta

Solution

Pteridophyta
Pteridophyta is the plant group known as vascular cryptogam due to the presence of hidden seeds and are vascular in nature.
Question 10
4 / -1

A group of plantae that represents smallest group with perennial plants only is

A
gymnosperms.

B
bryophytes.

C
angiosperms.

D
pteridophytes.

Solution

The plants of this group gymnosperms bear naked seeds and are perennial.
