Question 1
1 / -0.25

The production of new characteristics by introducing new genes and altering the genome is called

A
Genetics

B
Totipotency

C
Gene manipulation

D
Splicing

Solution

The production of new characteristics by introducing new genes and altering the genome is called Gene manipulation.
It includes gene splicing, use of recombinant DNA, forming of the monoclonal antibodies or PCR (polymerase chain reaction).
Gene Mechanism:
Question 2
1 / -0.25

Which of the following terms is used to describe the component isolated from a plant for in vitro culturing in the specific medium?

A
Explant

B
Callus

C
Embryoid

D
Synthetic seeds

Solution

Explant culture is an in-vitro technique to organotypically culture cells from a piece or pieces of tissue or organ removed from a plant or animal.
Question 3
1 / -0.25

To meet the demands of society, the in vitro production of a large number of plantlets in a short duration practized in the floriculture and horticulture industry is called ____ .

A
Hybridoma technology

B
Somatic hybridisation

C
Micropropagation

D
Somaclonal variation

Solution

Micropropagation is a type of vegetative propagation of plants in tissue culture . In this propagation the plantlets of plants growing in tissue culture in vitro condition and then growing them out.
Question 4
1 / -0.25

Protoplast is ______ .

A
Another name for protoplasm

B
An animal cell

C
A plant cell

D
A plant cell without a cell wall

Solution

Protoplasts are plant cells with the plasma membrane, cytoplasm, and nucleus, which have had their cell wall removed by the action of enzymes .
Once the cell wall has been removed the resulting protoplast is spherical in shape .
Question 5
1 / -0.25

In a tissue culture medium, the embryoids formed from pollen grains is due to

A
Double fertilisation

B
Test tube culture

C
Organogenesis

D
Cellular totipotency

Solution

Embryoid is a mass of tissue produced during culture. Formation of embryoid from pollen in tissue culture medium is due to cellular totipotency .
Cell potency is a cell 's ability to differentiate into other cell types. The more cell types a cell can differentiate into, the greater its potency.
Question 6
1 / -0.25

To obtain disease-free plants through tissue culture techniques, the best method is

A
Protoplast culture

B
Meristem culture

C
Embryo rescue

D
Anther culture

Solution

It is possible to produce disease-free plants through meristem culture because viruses move readily in the vascular system, which, in meristems, is absent.
Question 7
1 / -0.25

Somaclonal variation appears in plants

A
Raised in tissue culture

B
Growing in polluted soil or water

C
Exposed to gamma rays

D
Transformed by recombinant DNA technology

Solution

Somaclonal variation is the variation seen in plants that have been produced by plant tissue culture .
Question 8
1 / -0.25

Micropropagation is the ______ .

A
Propagation of microbes in vitro

B
Growing of plants on a small scale

C
Propagation of cells in vitro

D
Propagation of plants in vitro

Solution

Plant tissue culture specifically is also known asmicropropagation because it involves rapid multiplication of a small amount of plant material to produce more progeny.
Tissue culture is a technique of growing plant or animal cells, tissues, or organs in a sterilized nutrient/ culture medium under controlled environmental conditions.
Question 9
1 / -0.25

Mark the INCORRECT statement about agar, a gelling agent in plant tissue culture medium?

A
Not digested by plant enzymes

B
It does not use in micropropagation work

C
It does not react with media constituents

D
Remain stable at incubation temperature

Solution

Agar is obtained from seaweeds, and it is the most preferred gelling agent due to its advantageous properties.
It is used in some micropropagation work .
Question 10
1 / -0.25

Which one of them is NOT the main effect of polyamines in the tissue culture system?

A
Promotion of tuber and bulb formation

B
Adventitious root formation

C
Promotion of shoot formation

D
Somatic embryogenesis

Solution

Polyamines do not promote tuber and bulb formation, but it supports root and shoot formation and also somatic embryogenesis. The promotion of bulb and tumor formation is done by jasmonic acid.
