Question

Potato is an example of which type of stem?

Answer 1

Many plants' stems have been changed to serve a variety of purposes, including storage, protection, photosynthesis, support, propagation, and perennation. Adaptation and survival are aided by modifications.
The plumule of the germinating seed develops into stems. It produces leaves, fruits, and flowers, among other things. Nodes and internodes are the distinguishing characteristics of a stem. The stem's primary role is to sustain other sections of the plant as well as to conduct food, water, and minerals. Stems of some plants are transformed in various ways, including aerial, subaerial, and subsurface changes.

Complete answer:
Rhizome, corm, stem tuber, and bulb are the four types of modifications of the stem. Rhizomes are found in plants such as ginger. Corm includes plants such as Amorphophallus and Colocasia. The most common stem tuber is the potato, and the bulb is an onion.
Potato is a stem that is formed from stolons, which are underground stems. Potato tubers have buds that sprout leaves and stems, whereas potato roots lack these characteristics.
Underground stem modifications-
Rhizome- It runs parallel to the ground, with the upper half producing scaly leaves and the lower half producing adventitious roots. Nodes, internodes, and buds are all found in them. They are used to keep food.
Bulb- Modified bulbs can be recognised in the stem, which is shrunk and encircled with scale leaves.
Corn- It has a scaly stem with a short upright stem. When compared to bulbs, it is difficult.
Tuber- The fleshy terminal of the stem stores nourishment here. The stem has nodes and internodes; however, these are difficult to distinguish due to swelling. Eyes or scars can be visible where scaly leaves are present at nodes.

Note:
It uses diverse mechanisms to transport water, nutrients, and food to other areas of the plant body. The stem is changed in some plants to perform additional roles such as food storage, support, vegetative propagation, and protection. Modified stems are simply referred to as such, and they are divided into several categories.
Types of stem modifications-
1. Underground – Rhizome, Bulb, Corm, Tuber
2. Subaerial – Runner, Sucker, Offsets, Stolon
3. Aerial – Tendrils, Thorn, Bulbils, Cladode, Phylloclade
