5.18 understand how micropropogation can be used to produce commercial quantities of identical plants (clones) with desirable characteristics

If loads of plants are required, you can take cuttings from the explants to produce even more plants. It is also very quick so the farmer will not need to rely on the correct conditions like during natural growth - the commercial company can ensure they ill have stock (of plants).

NOTE: the process of micropropogation is explained in point 5.17.
