Answer: Stems are usually above ground, although the stems of some plants, such as the potato, also grow underground. Stems may be herbaceous (soft) or woody in nature. Their main function is to provide support to the plant, holding leaves, flowers and buds; in some cases, stems also store food for the plant.

Where is the stem of a potato plant?
Lateral stems are formed at the stem segment below ground or just above soil level. Branches of stems (3) higher up at main or lateral stem originate in axils where an inflorescence is formed.
What are the function of a stem in a plant Class 6?
The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.
What is the function of stem in the potato plant?
The potato stem is the communication and transport channel between the assimilate-exporting source leaves and the terminal sink tissues of the plant.
What is a potato stem called?
The tuber is modified for the storage of food. Potato grows on the underground stem. This stem is known as stolon.
Do potatoes grow from the stem?
The part of the plant we call a “potato” grows underground. It grows on a specialized underground stem called a stolon. So, although potatoes grow underground, they are stems, not roots, and are known as “tubers.”
How are potato plants produced Class 6?
The potato plant undergoes asexual reproduction via vegetative propagation. Vegetative propagation is the reproduction process in which new plant offspring can be formed from vegetative parts of the plant like root, stem and leaves. Potato contains small eyes/tubers that give rise to leaves in them.
What is the function of stem BYJU’s?
Support: Primary function of the stem is to hold up buds, flowers, leaves, and fruits to the plant. Along with the roots, a stem anchors the plants and helps them to stand upright and perpendicular to the ground.
What is stem and its function?
Stem arranges leaves in a way that it gets direct sunlight to perform photosynthesis. Xylem and Phloem conduct water across the plant. Stems stores food, water, and nutrients. Cells of a stem, meristems, produce new living tissues. Underground stem, Aerial stem, and subaerial stem are three different types of Stem.
What are the 5 functions of stems?
(i) It supports branches, leaves, flowers, and fruits. (ii) It transports water and minerals from the roots to the leaves and other parts of plants. (iii) It transports food from leaves to different parts of the plant. (iv) It holds the plant upright.
Why do we say that potato is an underground stem class 6?
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.
What are the 5 functions of roots?
Conclusion: Important functions of roots include anchorage of the plant, absorption of water and dissolved nutrients, their conduction to the shoot, storage of nutrients, vegetative propagation, and binding of soil particles.
Why potato is a stem for kids?
The potato is classified as a stem because it has several nodes, known as eyes, and space between each eye, known as internodes. The potato’s eye can grow into a shoot and a new plant. As a result, it is a vegetable with stems.
Which part of potato plant is used as food?
Detailed Solution
The underground stem of the potato is edible part of the plant. The stem of potato is also called the tuber.
What part of plant is potato?
Potato is a special kind of stem, which grows underground. It has buds called ‛eye’ on its surface. Any part of the potato with an eye or bud can grow into a new plant.
Are potato eyes roots or stems?
Potato tubers are not roots, but rather modified stems. These modified stems are used to store energy (in the form of carbohydrates).
Why do potatoes grow roots?
Potatoes sprout to produce a new plant. Enzymes in the potato convert starch into sugar. This sugar provides energy for sprouts to grow from the eyes (buds) of the potato. If you plant a potato, the sprouts grow toward the soil surface and produce leaves to create energy by photosynthesis.
Is Sweet Potato a root or stem?
Unlike the potato, which is a tuber, or thickened stem, the sweetpotato that we eat is the storage root of the plant; an enlarged lateral root.
How do potato plants grow?
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.
What type of plant tissue are potatoes and what is their main function in a potato plant?
Parenchymal cells retain the ability to divide to form other types of cells, much as stem cells do in our own bodies. Their primary functions are metabolism, including photosynthesis and cellular respiration, and storage. The flesh of fruits and vegetables such as potatoes are made of parenchymal cells.
What is asexual reproduction class 7th?
“Asexual reproduction is the mode of reproduction that does not involve the fusion of male and female gametes and produces individuals that are genetically identical to the parent.”
