Question 1
1 / -0.25

Modification and adjustment of an organism to local environment is called?

A
Selection

B
Introduction

C
Quarantine

D
Acclimatization

Solution

Modification and adjustment of an organism to local environment is called acclimatization. The newly developed varieties of crops are acclimatized in different environmental condition before releasing to farmers for raising crops.
Question 2
1 / -0.25

Which variety of wheat is used as donor for high protein?

A
IR-8

B
Sonalika

C
Atlas 66

D
Himgiri

Solution

Plant hybridization is also done to increase in nutritive value of crop plants. Wheat variety Atlas 66 has high protein value that is used as donor for high protein variety.
Question 3
1 / -0.25

In order to obtain disease-free plants through tissue culture techniques, the best method is?

A
Protoplasm culture

B
Embryo rescue

C
Anther culture

D
Meristem culture

Solution

Disease free plants can be obtained by the tissue culture of meristematic tissues present at shoot tips. The newly formed cells are generally disease free and plants obtained from this are also disease free.
Question 4
1 / -0.25

Which of the following is the consequence of plant disease?

i. Reduced yield.
ii. Lower quality of produce
iii. Increased cost of production
iv. Poisonous produce
v. Variation in the genome.

A
Only ii, iii, iv and v

B
Only i, iii, iv and v

C
Only iii, iv and v

D
Only i, ii, iii and iv

Solution

The consequences of plant disease are reduced yield, lower quality of produce, increased cost of production and sometimes poisonous produce. It do not produce variation in the genome.
Question 5
1 / -0.25

Gene banks comprise

A
Seed banks and cryopreservation

B
Seed banks, orchards, tissue culture and cryopreservation

C
Tissue culture and cryopreservation

D
Seed banks, tissue culture, and cryopreservation

Solution

Gene banks comprise Seed banks, orchards, tissue culture and cryopreservation. Genomes of different plants are preserved for used in genetic program like plant breeding.
Question 6
1 / -0.25

Which of the following fungi is used as food?

A
Rhizopus

B
Mushroom

C
Mucor

D
Bread mold

Solution

Mushrooms are eaten by many people and large scale mushroom culture is a growing industry. It is a rich source of protein and other micronutrients.
Question 7
1 / -0.25

Which of the following can yield a completely haploid plant?

A
Root tip

B
Anther

C
Carpel

D
Stem apical meristem

Solution

Anther can yield a completely haploid plant because anther is produced by meiosis cell division contain half the number of chromosome their normal cells have.
Question 8
1 / -0.25

Procedure between formation of plantlets in culture and establishment of seedlings in the field is called?

A
Regeneration

B
Somatic transfer

C
Transgene

D
Hardening

Solution

Procedure between formation of plantlets in culture and establishment of seedlings in the field is called hardening. Hardening is induced by keeping plantlets under low light intensity and high humidity.
Question 9
1 / -0.25

Single cell protein (SCP) is

A
Protein obtained from unicellular organisms.

B
Protein obtained from a clone of cells

C
Protein obtained from biomass of microorganisms

D
Biomass got from microorganisms

Solution

Single cell protein (SCP) is biomass got from microorganisms. Single cell proteins are alternate source of protein in much concentrated form.
Question 10
1 / -0.25

Assertion: Multiple shoots are produced in meristem culture.

Reason: Culture media contains cytokines for overcoming apical dominance.

A
Both assertion and reason are correct

B
Assertion is correct but reason is incorrect

C
Both assertion and reason is incorrect

D
Assertion and reason are correct but reason does not explain assertion

Solution

Multiple shoots are produced in meristem culture because culture media contains cytokines for overcoming apical dominance.
Question 11
1 / -0.25

The breeding of unrelated animals which may be between individual of same breed or between different breeds of different species is called?

A
In breeding

B
Hybridisation

C
Out-breeding

D
Cross breeding

Solution

Out-breeding is the breeding of the unrelated animal which may be of same breed without common ancestors or cross breeding or inter-specific hybridization.
Question 12
1 / -0.25

A lake near a village suffered heavy mortality of fishes within a few days. Consider the following reasons for this.

A
Heavy rain

B
Spraying of DDT by helicopter

C
Excess water

D
Change in temperature

Solution

Heavy mortality of fishes within a few days in lake is due to spraying of DDT on large scale. Excessive water and heavy rain as well as change in temperature do not cause large scale death of fishes in a lake.
Question 13
1 / -0.25

Honey is the food of high nutritive value and find use in?

A
Homeopathic system of medicine

B
Allopathic system of medicine

C
Indigenous system of medicine

D
All of the these

Solution

Honey is the food of high nutritive value and finds use in Indigenous system of medicine. Beeswax is used in preparation of cosmetic and polishes.
Question 14
1 / -0.25

Assertion: Fisheries has important place in Indian economy.

Reason: It provide income and employment to millions of farmers and fishermen particularly in coastal states.

A
Both assertion and reason are correct

B
Assertion is incorrect but reason is correct

C
Assertion and reason both are incorrect

D
Assertion is correct but reason does not explain the assertion

Solution

Fisheries has important place in Indian economy. It provides income and employment to millions of farmers and fishermen particularly in coastal states. It is an only source of income for many persons living near coastal areas.
Question 15
1 / -0.25

Individual related by descent and having a similar genotype constitute:

A
Breed

B
Line

C
Strain

D
Variety

Solution

All the individuals related by common descent and having a similar genotype constitute a line. Pure line is obtained by successive breeding.
