Micropropagation technique is considered as an advanced tool in plant cultivation. A small piece of tissue is enough for growing large number of plants simultaneously. Tissue culture helps to maintain genetic makeup of parent plant over generations and offsprings are grown at much faster rate than other conventional methods. Which one of the following features is not applicable in case of ‘micropropagation’.
Large variety of plants can be grown in limited space.
Commercially important phytochemicals can be obtained from callus without sacrificing the whole plant.
Plants grow in disease free environment which helps in higher yield.
Any type of plant tissue can be used as explant in micropropagation.

Answer:
1. Bioactive phytochemicals. ... As phytochemicals can be directly extracted from calli without sacrificing the entire plant, the callus technology may help to protect rare and endangered plant species, and sufficient amounts of secondary metabolites can be produced in vitro.
2. Exploitation of somaclonal variation can help in inducing variability, leading to high-yielding, high-quality, and disease-resistant lines.
3. Micropropagation starts with the selection of plant tissues (explant) from a healthy, vigorous mother plant [15]. Any part of the plant (leaf, apical meristem, bud and root) can be used as explant.
