Is potato an underground plant?
Potatoes are perennial plants planted in the spring and harvested in the fall. Potatoes grow underground on a special stem called a ‘stolon’.

Why potato is called modified stem?
This is why potatoes are also called tuberous stems. Eyes of potatoes are axillary buds that contain several small buds at each side. Sometimes buds can expand to form new shoots which later grow on to make new plants. Hence, potatoes are called modified stem because of (B) Tuber.
Why are underground stems?
Underground stems are modified plants that derive from stem tissue but exist under the soil surface. They function as storage tissues for food and nutrients, propagation of new clones, and perennation (survival from one growing season to the next). Types include bulbs, corms, rhizomes, stolons, and tubers.
Why potato is called underground stem Brainly?
The potato tubers are actually thickened stem they have buds that sprout stem and leafs. Roots can’t do that. And the potatoes are under the ground so they are called underground stem.
What kind of stem is a potato?

As the potato plant grows, its compound leaves manufacture starch that is transferred to the ends of its underground stems (or stolons). The stems thicken to form a few or as many as 20 tubers close to the soil surface. The number of tubers that actually reach maturity depends on available moisture and soil nutrients.
Why potato is not a root?

Sometimes the rhizomes are condensed into solid swollen forms which are then known as corms. The tubers are also underground parts, which may either be modified roots or stems.
Is onion underground stem?
An onion is a type of underground stem structure that has been modified. The bulged leaf structure at the base of the onion plant stores its processed food.
Why underground stem is different from roots?
Hint: Underground stems are modified plants that are developed from stem tissue but present under the soil surface. The elongation of the radicle leads to the formation of the primary root. The stems have buds that may be terminal or axillary whereas the roots do not have buds.
What is a potato underground?
