With reference to plants, micropropagation in vitro means :
Answer: B
Micropropagation means the production of a large number of progeny plants.
It is the rapid clonal multiplication of a plant in vitro: small explants such as shoot tips or nodes are grown on a sterile nutrient medium with hormones, the shoots multiply, and each is rooted to give a plantlet. Thousands of genetically identical plants can be raised from one parent in a short time.
The 'micro' refers to the small explants and culture vessels, not to tiny plants or plants at 'microlevel'. Raising plants from microspores is anther or pollen culture, which gives haploids.
