Tissue culture is the growth of tissues or cells separate from the organism. This is typically facilitated via use of a liquid, semi-solid, or solid growth medium, such as broth or agar. Tissue culture commonly refers to the culture of animal cells and tissues, with the more specific term plant tissue culture being used for plants.
ADVERTISEMENTS: The below mentioned article provides an outline of a plant tissue culture laboratory. Introduction: Plant tissue culture is not a separate branch of plant science like taxonomy, cytology, plant physiology etc. Rather it is a collection of experimental methods of growing large number of isolated cells or tissues under sterile and controlled conditions.
agar according to the free Science Dictionary = a colloidal substance (gel) extracted from certain red algaes and used in tissue culture, supplemented with nutrients as required.
PLANT TISSUE CULTURE Background . Weigh out 10 grams of agar and add it to the MS solution. Heat the solution gently while stirring until all the agar has dissolved. 3. Pour the still warm medium into the polycarbonate tubes to a depth of about 4 cm which will use about 15ml of media per tube.
Agar (/ ˈ ɑː ɡ ər /) or agar-agar, is a jelly-like substance, obtained from red algae.. Agar is a mixture of two components: the linear polysaccharide agarose, and a heterogeneous mixture of smaller molecules called agaropectin. It forms the supporting structure in the cell walls of certain species of algae, and is released on boiling.
Apr 26, 2018· Agar can be used to culture microbes, and agar slants are designed to allow for more growth, since the slant increases the medium's surface area. Agar While it is commonly used to grow bacteriological cultures, the agar must be impregnated with nutrients such as beef extract and peptone in order to support life.
YM (yeast extract, malt extract agar) has a low pH, deterring bacterial growth. MacConkey agar is for Gram-negative bacteria. Hektoen enteric agar is selective for Gram-negative bacteria. HIS-selective medium is a type cell culture medium that lacks the amino acid histidine.

Protocols. Agar has long been used to solidify media for plant tissue culture. The type of agar or gelling agent used can influence the growth of the tissue in culture. Both purity and cost of the gelling agent.
