mention the significance of tissue culture ?
Answers
Its importance are as follows:
1.From tissue culture studies it is possible to know how simple cells differentiate and become specialized to perform special functions.
2.Interrelationship between two cells can be studied in tissue culture.
3.Relationship between growth and differentiation can be well understood from such a culture.
4.By tissue culture method new plant variants can be obtained by isolating genetically unique cells. From callus cultures of tobacco, carrot, asparagus etc. new plants are formed. Such plants show genetic variability.
5.Tissue culture has great significance in pathological studies. The effect of various medicine on cells infected by pathogens can be studied in tissue culture.
6.Tissue culture technique is employed in the studies of plant tumour diseases and host parasite relationship. Disease free plants can be produced by tissue culture technique.
I think this answer is enough. You can cut down a few points if you want to...
Answer:
Tissue Culture:
The procedure in which a small tissue pieces or organs is removed from a donor plant and cultured aseptically on a nutrient medium is called Tissue Culture. This production is also known as micropropagation technique. The synthetic medium contains all the nutrients and hormones which are required for the growth.
A cell or tissue is transferred into suitable synthetic medium under sterile conditions. The tissue then develops into a fast growing cellular mass called callus. The callus is transferred to another medium for growth and differentiation that forms plantlets. The plantlets can be transplanted into soil or pots where they can be grown to maturity.
Tissue culture technique is being popularly used in agriculture and horticulture. It is used for production of ornamental plants like Orchids, Dahlia and Carnation. Other examples are Banana, Fig, Lemon, Potatoes, etc.
