Explanation:
Detailed explanation-1: -The most commonly used tissue explants are the meristematic ends of the plants like the stem tip, axillary bud tip, and root tip. These tissues have high rates of cell division and either concentrate or produce required growth-regulating substances including auxins and cytokinins.
Detailed explanation-2: -Plant tissues that consist of meristematic cells, have less cell walls or fibers, or are rich in cytoplasm are usually good candidates for explants. Examples are root tips, shoot tips, young floral organs, immature embryos, young leaves and young stems. Explants need to be surface sterilized.
