Explain the meaning of biotechnology and its impact on agricultural management with suitable example.

Answer: 1) For the benefit of human beings, biotechnological techniques are carried out. These methods are for bringing about improvements in living organisms by artificial genetic changes and by hybridization. All such techniques are together called biotechnology.

2) biotechnology includes the technique of modification in the DNA of crops. Then genetically modified crops possess required features.

3) due to use of this technique a new variety can be formed that can withstand the changes in the environment.

4) genetically modified crops can resist the change in temperature, dry and wet drought, climate change and some other environmental factors.

5) Genetically Modified crops are resistant to insect pests, pathogens and some other chemicals which are harmful to human beings.

6) Due to the use of seeds of GM crops better quality crops can be obtained.

7) Due to the use of biotechnology there is also a decrease in loss of crops.

8) Bt Cotton, Bt Brinjal, Bt Rice, is widely used in Maharashtra.

Which two main techniques are used in biotechnology? why ?

1. Genetic engineering and tissue culture are the two main technique which are used in biotechnology.
2. In the genetic engineering, nucleotide sequence is changed and thereby genes are manipulated.
3. In the tissue culture method, A compete organism can be developed from a single cell by the tissue culture methods.
4. main bahut genetic engineering and tissue culture cash crops production is increased.

Define the term tissue cultural and explain the concept of tissue culture.

1. Tissue culture is a technique in which ex Vivo growth of cell or tissues in an aseptic and nutrient rich medium is done.
2. While performing experiment of tissue culture a liquid or gel like medium is prepared from agar which is used as a nutrition medium.
3. Primary treatment, routing and shooting etc. are the different work done in the tissue culture.
4. required tissues are taken out and all the processes are carried out in an aseptic medium in laboratory.

‘Rearing of ship is a livestock’ Justify this statement.

1. In India sheeps are used obtaining Meat and wool.
2. Meat industry use sheeps to a large extent in India.
3. Wool of sheep has great demand in market.
4. Sheeps are also used to obtain natural manure.
5. They are small in size therefore they can manage by the lady of the house.
6. Thus, Rearing of sheep is a livestock.
