Question

ION MICROPROPAGATION hardly grow growth, but elopment of ts of these side plants nutripproAT Under appropriate conditions, including the provisionrvides a semisolid Sp small cuttings or individual plant cells can be grown in levels of mineral the ight, h vitro. During tissue culture the e multiplied by inducing large numbers of shoots to form. These are separated and develop into individual plants, which can be acclimatised to normal conditions and returned to the soil. This process is known as micropropagation. rate;+*+ Micropropagation is used not only for multiplying up large numbers of clonal plants but is also used to produce pathogen-free plants. Meristems and shoot tips usually vascular connections and so are usually virus-free. Hence micropropagation this source allows production of vírus-free plants (e.g. potatoes and strawberries) Micropropagation is also essential as a tool for use in genetic engineering. If genes are inserted into a single plant cell, it must be grown in tissue culture into a new plant 0 Question 14 What is totipotency? Question 15 Why are sterile conditions required for micropropagation? Question 16 Why are the Petunia shoots placed on fresh media to form roots? Lab 7

Explanation / Answer

(14)Totipotency is the genetic property of a plant cell to divide and differentiate to produce an entire plant.

(15)Since the micropropagation involves the generation of a large number of pathogen-free plantlets from a small amount of tissue, it is important to keep the tissue in sterile conditions to avoid viral/fungal pathogens.
