Answer:
False
Step-by-step explanation:
Parts of the plant growing below the ground are considered as root system. While part of plants growing above the ground are known as the shoot system. Though both tuber and rhizomes are found below the ground , they are not the part of root system. Tuber and rhizome are part of shoot system.They both are stem that grows below the ground and have buds and food reserves which make them edible. Some example of edible stems are - potato, ginger etc,
Thus the statement "Tubers and rhizomes are part of the root system" is false.
