In micropropagation, where are cells to be cloned usually taken from?
A
leaves
B
shoot apex
C
xylem
D
phloem
Explanation: 

Detailed explanation-1: -Micropropagation is a method of plant propagation using extremely small pieces of plant tissue taken from a carefully chosen and prepared mother plant, and growing these under laboratory conditions to produce new plants. It is widely used in commercial horticulture.

Detailed explanation-2: -Micropropagation is a process by which very small pieces of plants (known as explants) are grown in vitro using nutrient media. This allows plants to be cloned. Micropropagation can be used to clone plants with desirable characteristics such as pest resistance or high fruit yield.

Detailed explanation-3: -When virus elimination is the objective, to obtain disease-free plants, shoot tips of up to 10 mm are used. For rapid clonal propagation, a shoot-tip culture is followed in which (5–10 mm) explants are used. Hence, the majority of meristem culture are essentially shoot-tip cultures.
