Hint: The practice by which plants, as well as livestock, are cultivated and looked after is known as agriculture. It is the prime source of food for the population. Agriculture has many sub divisions depending on the nature of cultivation.

Complete answer:
In agriculture, the crops can be altered to improve the yield or to increase the benefit to the cultivator. Such plants which are altered are known as Cultigens. Also known as cultivated plants.
