C. Explant `to` Cell division `to` Callus `to` Addition of cytokinin `to` Cells acquire meristematic property
D. Callus `to` Explant `to` Cell division `to` Addition of cytokinin `to` Cells acquire meristematic property

Answer

C

Explanation

Callus culture is a type of in vitro plant tissue culture.The process is carried out under controlled conditions.The selected cell, tissue or organ is called-explant.The number of cells increases through cell division.However, these cells are unorganized and collectively constitute a callus.They are maintained on agar-agargel . Growth promoters like auxin and cytokinins are added to the culture.Under these condition, the cells become meristematic and begin to divide.Callus to obtained within 2 to 3 weeks.
