Weekly Quiz Competition

Question 1
1 / -0

Which of the following can be used for cultivation of SCP?

A
Animal manure

B
Straw

C
Molasses

D
All of these

Solution

Large quantities of single cell proteins like Spirulina can be grown easily on materials like waste water from potato processing plants, straw, molasses, animal manure and even sewage.
Question 2
1 / -0

The term 'totipotency' refers to the capacity of a:

A
Cell to generate whole plant.

B
Bud to generate whole plant.

C
Seed to germinate.

D
Cell to enlarge in size.

Solution

The capacity to generate a whole new plant from any cell is called totipotency. That whole plant could be regenerated from explants ( any part of plant that taken out and grown under sterile conditions in a special nutritive media).
So, the correct option is 'Option A' .
Question 3
1 / -0

Single cell protein can be obtained from

A
bacteria

B
algae

C
fungi

D
all of these

Solution

Single cell protein can be obtained from cells of microorganisms such as yeast, fungi, algae and bacteria which are grown on carbon sources for synthesis. SCP is a protein supplement for animals and humans. Example ; Spirulina produces large quantity of food which are rich in protein, carbohydrates, fats, minerals and vitamins. It also reduces environmental pollution.
So, the correct option is 'Option D' .
Question 4
1 / -0

Micropropagation involves ____________________.

A
Vegetative multiplication of plants by using microorganisms

B
Vegetative multiplication of plants by using small explants

C
Vegetative multiplication of plants by using micro-spores

D
Non-vegetative multiplication of plants by using microspores and megaspores

Solution

Micropropagation is the tissue culture technique used for rapid vegetative multiplication of ornamental plants and fruit trees by using small sized explants.
Question 5
1 / -0

'Golden rice' developed through transgene approach is enriched with

A
High lysine content

B
High methionine content

C
High glutenin content

D
High vitamin A content

Solution

Rice is a staple food in many countries, particularly in Asia, but does not contain vitamin A or its immediate precursors. By inserting two genes from Daffodil and one gene from a bacterial species into rice plants, Swiss researchers have produce rice capable of synthesizing β-carotene, the precursor of vitamin A. It is needed by the retina of the eye in the form of retinal, which combines with protein opsin to form rhodopsin, the light-absorbing molecule necessary for both low-light and color vision.
Deficiency of vitamin A causes night blindness and skin disorders. This rice is called 'Golden rice' because of yellow colour of rice grains due to the presence of β-carotene.
So, the correct answer is 'High vitamin A content'.
Question 6
1 / -0

Golden rice is yellow in colour due to the presence of

A
Riboflavins

B
$$\beta$$-carotene

C
Vitamin $$B_1$$

D
Complex genetic material

Solution

Rice is a staple food in many countries, particularly in Asia, but does not contain vitamin A or its immediate precursors. By inserting two genes from Daffodil and one gene from a bacterial species into rice plants, Swiss researchers have produce rice capable of synthesising β-carotene, the precursor of vitamin A. Vitamin A is required by all individuals as it is present in retina of eyes. Deficiency of vitamin A causes night blindness and skin disorders. This rice is called 'Golden rice' because of yellow colour of rice grains due to the presence of β-carotene.
So, the correct answer is 'β-carotene'.
Question 7
1 / -0

A collection of all the alleles of all the genes of a crop plant is called:

A
Germplasm collection

B
Protoplasm collection

C
Herbarium

D
Somaclonal collection

Solution

The entire collection having all the diverse alleles of all the genes in a given crop is called germplasm collection. It is used to evaluate the desirable combinations of characters in plants. It is the first step in the process of plant breeding.
So, the correct option is 'Option A' .
Question 8
1 / -0

Select the correct statement regarding an improved variety of transgenic basmati rice. i.e. golden rice.

A
It does not require the use of chemical fertilisers

B
It is completely resistant to all insect pests and diseases

C
It gives high yields but not characteristic aroma

D
It gives high yields and rich in vitamin A

Solution

Rice is a staple food in many countries, particularly in Asia, but does not contain vitamin A or its immediate precursors. By inserting two genes from Daffodil and one gene from a bacterial species into rice plants, Swiss researchers have produce rice capable of synthesizing β-carotene, the precursor of vitamin A. Vitamin A is required by all individuals as it is present in retina of eyes. Deficiency of vitamin A causes night blindness and skin disorders. This rice is called 'Golden rice' because of the yellow colour of rice grains due to the presence of β-carotene.
So, the correct answer is 'It gives high yields and rich in vitamin A'.
Question 9
1 / -0

The biggest constraint of plant breeding is

A
availability of desirable gene in the crop and its wild relatives

B
infrastructure

C
trained manpower

D
transfer of genes from unrelated sources

Solution

Plant breeding is the process where the desired gene from the wild type is introduced in the plants. The genes can only be transferred from the wild type when it is a related species.
Here some of the factors that have to be kept in mind are-
the selection of the variety of crops and their genetic constituents.
The wild variety which is taken should be disease free.
So, the correct option is 'availability of desirable gene in the crop and its wild relatives'
Question 10
1 / -0

The agriculture sector of India employs about:

A
$$50$$ percent of the population.

B
$$70$$ percent of the population.

C
$$30$$ percent of the population.

D
$$60$$ percent of the population.

Solution

The agriculture sector of India employs about 70 percent of the population, in which 80% are rural population. The agriculture share in the GDP of India is 20.5 %.
So, the correct option is option B '70 percent of the population'.
