Rhizome- is a thickened underground stem that has distinct nodes and internodes and scaly leaves at the nodes. Example: Ginger. Tuber- is a horizontal underground stem that becomes enlarged at its growing tips due to the accumulation of stored food, commonly starch. E.g. Potato. Bulb- It is a short underground stem with a fleshy base with leafy ...
Plants use underground stems to multiply their numbers by asexual reproduction and to survive from one year to the next, usually over a period of dormancy. Ginger is an underground stem and not root because it has nodes and internodes and not because it lacks chlorophyll, it stores food and had vessels and xylem. Thus, the correct answer is ...
(A) A piece of underground branches store (I) Mentha food material (B) Underground branches grow obliquely upward from the axillary buds of nodes of the stem below the soil. (II) Hydrocotyl (C) Aerial branches grow obliquely downwards. (Ill) Agave and produce adventitious roots after touching the soil (D) Weak stemmed plants have a cluster of ...
An example of edible fungus is. Statement 1 : The stem tubers are the swollen ends of specialized underground stem branches, which help in vegetative propagation of the plant. Statement 2 : Solanum tuberosum is an example of a stem tuber which stores inulin as the main reserve food material.
Rhizomes are modified stem that grows horizontally at a particular depth and can store food like in ginger and turmeric. A corm is an underground modification of stem that is made for storage as in Colocasia and Saffron. A tuber is a modifies stem that gets swollen due to the accumulation of starch and protein like a potato.

Ex- Ginger, Turmeric, Canna, Water lily and Banana. -Corm: It is a condensed structure which grows vertically under the soil surface. They possess spherical node and internode and they possess contractile roots. Ex- Colocasia, Alocasia, Zaminkand, etc. -Stem tuber: The tip of underground branches become swollen in the soil.
Underground stems are modified plant structures that are derived from stem and are present under the soil surface. Examples of underground stems include corms, bulbs, rhizomes, tubers. They perform various functions such as storage tissues for food and nutrients, in reproduction by propagation of new offspring, in perennation by allowing survival from one growing season to the next.
A thickened underground stem X of a plant which is swollen with stored food has a number of points Y on its surface. When the old stem X is planted in the soil of a field in the next growing season, then each point Y present on its surface grows into a new plant. (a) What is the general name of the underground stems like X? (b) Give one example ...
The true stem is present below the soil as modified stem known as a rhizome. The leaf base known as hyphopodium leads to the production of the thin slender stem-like structure known as suckers above the soil.
