The following passage contains information about using micropropagation to produce plants.
Complete the passage by writing a suitable word in each blank space.
Micropropagation uses small fragments of plants which are regrown into whole plants. These fragments of plants are known as
The surface of each fragment is sterilised to prevent growth of .The fragments are placed in a growth medium. The growth medium contains agar and a source of energy such as .
This method is able to produce large quantities of genetically identical plants called .
One advantage is that micropropagation is quicker than reproduction, which involves flower and seed production. Another advantage of micropropagation is that plants can be produced the year.
