How is a stem helpful to a plant?

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. …

Which plant grow from underground stem?

Many plants have underground modified stems that may be mistaken for roots. Examples of underground stems include corms, such as taro (left); rhizomes, such as ginger (center); and tubers, such as potatoes (right).

What is the purpose for underground storage for plants?

A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. Storage organs often grow underground, where they are better protected from attack by herbivores.

Which stem are used as vegetable?

Stem vegetables include asparagus and kohlrabi. Among the edible tubers, or underground stems, are potatoes. The leaf and leafstalk vegetables include brussels sprouts, cabbage, celery, lettuce, rhubarb, and spinach. Among the bulb vegetables are garlic, leeks, and onions.

What are called underground stems?

Roots, rhizomes, bulbs, and tubers Rhizomes are underground stems which grow beneath the surface of soil; they are frequently fleshy and serve as organs of food storage. Sometimes the rhizomes are condensed into solid swollen forms which are then known as corms.

What are roots used for?

The roots anchor a plant, absorb water and minerals, and provide a storage area for food.

What is the function of 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).

What is the underground part of the plants?

Roots
Roots are the important and underground part of a plant, which are collectively called the root system. They are the major part that anchors the plant firmly in the soil. They absorb water and minerals from the soil, synthesise plant growth regulators, and store reserve food material.

How are plants modified to grow horizontally underground?

Modified stems that grow horizontally underground are either rhizomes, from which vertical shoots grow, or fleshier, food-storing corms. New plants can arise from the nodes of stolons and runners (an aboveground stolon): stems that run parallel to the ground, or just below the surface.

Why do plants produce stems in the ground?

Some plants produce stems modified to store energy and preserve a location of potential growth to survive a cold or dry period which normally is a period of inactive growth, and when that period is over the plants resume new growth from the underground stems.
