How does micropropagation work
Find a plant with desirable characteristics that you want to clone.
Take very small pieces of plant tissue (called explants) from the tips of stems.
Sterilise the explants to remove any microorganisms.
Place the explants in a nutrient medium (agar) and let them grow into small masses of cells called calluses. The nutrient medium should also contain growth hormones.Â
Transfer the calluses to soil where they can grow into plantlets (basically baby plants).
The plantlets can then be transferred to their own pots to develop into genetically identical adult plants.
What is an explant
A small piece of plant that can develop into a clone
Benefits of cloning via cuttings
It is quicker than micropropagation
It is cheaper
Give two nutrients that should be added to the agar medium. Explain how each nutrient helps plant growth
Glucose for energy and respiration
magnesium for chlorophyll and chloroplast
