Answer 2

Explants are the plants taken from different parts of the plant.

• These plants represent minute pieces of sections of plants or organic tissues that are aseptically cut
• They are naturally used to promptly initiate an intensive culture in a nutritive form.
• Explants can be naturally taken from various active parts of a flowering plant, such as leaves, tiny flowers, roots and shoots, and also the stems.
• They can equally be extracted from many mature cell types, provided that they can accurately de-differentiate into totipotent cells.
• They are helpful in understanding tissue culture.
