A general connotation of Biotechnology is industrial utilization of biological processes. In culture methods, cell suspension refers to a type of culture where cells are suspended in a liquid medium. Cell Culture Cell culture is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (e.g., metabolic studies, aging), the effects of drugs and toxic compounds on the cells, and mutagenesis and carcinogenesis. For this, an embryo is isolated from a living organism. Organ cultures are mainly done for highly specialized parasites of certain organs e.g. The objective of this conference is the use of plant tissue culture as a plant production system for horticultural crops, and my role is to discuss the principles of plant tissue culture with respect to this objective.

Sterilising procedures are needed for plant materials that are to be used … Callus Culture • In Callus culture, cell division in explant forms a callus. Once the cells have been cultured, they can be used in many different types of studies, including studies on the biochemistry of the tissues and the development of medications. To obtain single cells, a friable callus (small tissue that falls apart easily) is put in agitated liquid medium (agitation allows for gaseous exchange unlike solid medium), breaking it up. The callus is a mass of undifferentiated and unorganized cells that can differentiate into any type of cells in the plant body. In other words, it is an in vitro culture of plant cells or tissues on an artificial nutrient media under aseptic conditions, in glass containers.. Organic compounds ?
