Tissue culture of the tobacco plant Nicotiana tabacum growing in a petri dish on nutrient agar. The tissue cultures are grown from tobacco calluses,parenchymatous cells that form around a wounded plant surface. The mass of undifferentiated cells,or even a single cell,is placed on a sterile culture medium containing salts,a variety of organic materials,vitamins & growth substances. After a period of time shoots & leaves emerge & a normal,healthy plant is regrown. Tissue culture has various applications in plant breeding | |
