Biotechnology
Term is derived from a fusion of Biology & Technology
The Application of biological organisms, systems or processes
![Page 4: Tissue Culture and Basics of Biotechnology](https://reader035.fdocuments.net/reader035/viewer/2022062823/58757cdb1a28ab78498b6527/html5/thumbnails/4.jpg)
Biotechnology - as a science that utilizes biological entities like cells, organisms or parts
there of to develop or enhance products or processes.
Biotechnology, defined broadly, is the engineering of organisms for useful purposes.

Karl Erekey, 1917
coined the term Biotechnology

Biotechnology in India
Importance of Biotechnology was highlighted by the 69th session of the Indian Science Congress held at Mysore, 1982.
National Biotechnology Board (NBTB) to encourage and coordinate research activities in Biotechnology.
1986, a separate Department of Biotechnology was created within the Ministry of Science & Technology.

Research Centres for Biotechnology have been organized at:
Indian Agricultural Research Institute, New Delhi.National Dairy Research Institute, Karnal.Indian Veterinary Research Institute, Izat Nagar.
IARI centre has been named as National Research Centre for Plant Biotechnology, it cames under operation in
1993.

An International Centre for Genetic Engineering and Biotechnology has been established by the United
Nations Organisms (UNO).
It has Two Centres, One centre is located at Trieste, Italy.Other is located at New Delhi. (Operate year 1987)

DBT has initiated an extensive programme for manpower development in Biotechnology.
This programme has two components
Master Level training at 19 centres located in the different Universities.
Post doctoral training at three centres.

Plants are living organisms belonging to the kingdom Plantae.
The group is also called green plants or Viridiplantae in Latin.

Plants are one of the two groups into which all living things have been traditionally divided; the other is animals.
Place (a seed, bulb, or plant) in the ground so that it can grow.

Plant Parts & their Functions
Leaf (Photosynthesis)
Shoot (Mechanical support, Transport of food)
Root (Water and mineral supply)

• Plants - source for food, fiber and fuel. Besides these - source of diverse array of chemicals as flavors, fragrances, natural pigments, pesticides and pharmaceuticals (Plants derived secondary metabolites) thus plants are invariably the integral part of human life.
