The stored food in tubers is used to grow stems. Therefore, the potato is an underground stem because it possesses axillary buds called eyes. They are underground stems not because they lack chlorophyll. Also, they do bear roots and contain reserved food.
Which potato is called underground stem?
Solanum tuberosum is the scientific name for potato. It’s an annual plant in the nightshade family. The tuber is modified for the storage of food. Potato grows on the underground stem. This stem is known as stolon.
Why are they called underground stem?
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 is potato called a stem?
Complete Answer:
Potato grows on the end of the underground stem known as the stolon. – Potato is considered as a stem because it has many nodes called the eye and space between each eye is called the internodes. The eye of the potato can develop into a shoot and a new plant. Thus it is a stem vegetable.
Are potatoes underground stems?
The potato (Solanum tuberosum) is an herbaceous annual that grows up to 100 cm (40 inches) tall. 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.
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.
Why potato is not a root?
As i said earlier, potato have buds on it, which under the right conditions can lead to the growth of a new plant. Actually the presence of these buds make it a stem, because roots do not havr buds from which new plants can come.
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.
Why is potato and ginger a stem?
The stems of potatoes and ginger have been modified. Tuber refers to both the underground and modified stem of the potato. Rhizome refers to the underground as well as modified stem of ginger. These plants, like other plants, photosynthesize through their leaves.

Why potato is a stem and sweet potato is a root?
Solution : Potato is underground tuber (stem) on which nodes and internodes with adventitious buds (in eyes) are present. Scale leaves are absent. Sweet potato is underground modified tubercled adventitious root which is non-green and swollen. Scale leaves, nodes, internodes are absent.
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.
What type of root is a potato?
Potatoes produce a fibrous root system. These roots are at best no more than 24 in long. Thus potatoes are shallow rooted compared to cereals for example, which can root to at least 47 in depth. As a result, potatoes are often unable to exploit nutrients and soil moisture at depth within a soil profile.
How do potatoes grow without seeds?
Potatoes are mainly propagated by vegetative methods (cloning). Potato tubers have nodes or eyes from which the new growth begins. The new stems growing from each eye are called sprouts which giver rise to the new plant. Vegetative seed can be either a whole tuber or a cut tuber.
Which part of plant is potato?
