Callus is just a lump of cell/tissue. A plant needs roots to survive. that's why callus is kept in a rooting medium where it grows roots (several saplings as a aingle structure).
Callogenesis is the shoot development in callus, due to low auxin and hign cytokinin concentration in the culturing medium during tissue culture.

It is just a type of a culture medium. The "L" there stands for Lebowitz, presumably the last name of the first person who came up with that culture medium.
A nutrient medium is used.
TCBS
In tissue culture, the medium also called the sterile jelly is very essential because it provides all the necessary nutrients , hormones , enzyme which is needed for the growth and development of the tissue and helps it to produce many cells which form a shapeless mass called a 'callus' .This then could be transferred to another jelly which helps it to develop roots and another to develop shoot which then could be transplanted to pots or soil which helps it to mature and grow to form new plant . hence medium is considered very important in tissue culture technique.
Usually a sterile mix of vermiculite, pearlite, moss, and steralized soil.
Depends entirely on the species of plant. Some plants have to be placed in the medium directly after cutting to prevent air bubbles entering the vessels and causing blockages. Others can be left out for a number of days or even weeks before planting as they form a callus layer before rooting - eg. Frangipani (Plumeria species)
Callus stageTissue is grownin nutrient medium till it forms an unorganised mass called callus.Plantlet stageThe callus is transferred to another medium for growth and differentiation, that forms plantlets.Maturity stageThe plantlets are transplanted into soil or pots where they grow to maturity.
Callogenesis is the shoot development in callus, due to low auxin and hign cytokinin concentration in the culturing medium during tissue culture.

Disturbances that transfer energy, or waves. Mechanical waves must have a medium to travel.
Protein signals cause cells to divide in a culture medium.
Stewart's medium is a type of culture transport medium (in broth form) used to preserve bacteria until it is cultured. Stewart's medium can be found in specific culture test tubes.
A nutrient medium is used.
