1 / -0

The Ear cockier of wheat can be differentiated from Molya disease of wheat by the fact that in the former.

A
Plants become dwarf, stem and leaves become twisted spike lets get distorted and grains get replaced by brown stony structures

B
Plants become pale, leaves turn yellow with reddish lip, roots get matted and fail to ear

C
Root tips swell and cyst adheres to roots that turn brown and fall

D
Show hypertrophy of stern and leaves and roots swell
Question 2

Tissue culture is recommended for.
a. Multiplication of elite genotypes
b. Developing virus-free plants
c. Production of secondary metabolites
d. Induction of polyploidy
e. Multiplications of useful trees

A
$$1, 2$$ and $$4$$ are correct

B
$$1, 2$$ and $$3$$ are correct

C
$$1, 3$$ and $$4$$ are correct

D
$$2, 3$$ and $$4$$ are correct
Question 3
1 / -0

Chemosynthesis is best defined as _________________.

A
Synthesis of food by chemical means

B
Synthesis of a chemical compound

C
Synthesis of food with energy obtained in a chemical reaction

D
Absorption of food material in various parts of the body
Question 4
1 / -0

Which of the following statements are correct?
a. Callus is the disorganised mass of cells formed under in vitro condition.
b. Totipotency is the ability of a plant organ to regenerate an entire organism when cultured in a suitable medium.
c. Embryoid is the embryo-like structure formed under in vitro condition which has the potentiality to develop into a plantlet.
d. Explant is the excised portion of plant tissue or organ which is used in tissue culture study.
Select the correct answer using the codes given Codes.

A
$$1, 2$$ and $$4$$

B
$$1, 3$$ and $$4$$

C
$$1, 2$$ and $$3$$

D
$$2, 3$$ and $$4$$
Solution
- Callus is defined as a group of cells derived from competent source tissue that is cultured under in vitro conditions to form an undifferentiated mass of cells.
- Totipotency denotes the ability of a cell to generate an entire organism. For instance, if separated, each blastomere from a mouse 2-cell embryo is capable of developing into a complete organism.
- An explant is a cell, organ, or piece of tissue which has been transferred from animals or plants to a nutrient medium.
- Embryoid bodies are aggregates of pluripotent cells that are induced to differentiate by a combination of a change in culture medium (removal of factors that support pluripotency) and allowing the cells to interact in three-dimensional structures.
So, the correct option is 'A'.
Question 5
1 / -0

Germplasm conservation at liquid nitrogen temperature is

A
Stratification

B
Scarification

C
Cryopreservation

D
None of the above

Solution

Germplasm conservation at liquid nitrogen temperature is called cryopreservation. It is an example of Ex-situ conservation. Ex-situ conservation is done by preserving the components of biological diversity outside their natural habitats. It is done by conserving genetic resources, as well as wild and cultivated or species. Other examples include gene banks, microbial cultures, etc.
So, the correct answer is 'Cryopreservation'.
Question 6
1 / -0

Which spice of Italian honey bee is useful for honey production?

A
Epis serena indica

B
Epis flora

C
Epis corseta

D
Apis melliphera

Solution

The Italian honey bee, Apis mellifera ligustica, is now the world's most widely distributed honey bee due to the prolific egg-laying of the queens.
So, the correct answer is 'Apis melliphera'.
Question 7
1 / -0

A
Karnal

B
Hisar

C
Anand

D
Jaipur

Solution

The national Dairy Research Institute , Karnal is India's premier for dairy research .The institute was accorded the status of Deemed University in the year 1989.
