A rhizome is an underground stem that can produce new leaves and roots. It grows horizontally underground and can send out shoots and roots at various points. Examples of plants with rhizomes include ginger, bamboo, and iris.
A tuber is a swollen, underground stem that stores nutrients for the plant. It differs from other plant structures like roots and stems because it is a specialized storage organ that can be used for reproduction or survival during harsh conditions.
The scientific name for roots is "radix." Roots are the underground part of a plant that anchors it to the soil and absorbs water and nutrients.
A tuber is a swollen underground stem used for storing nutrients, while a root is a part of the plant that absorbs water and nutrients from the soil. Tuber stores energy for the plant, while roots help in anchoring the plant and absorbing nutrients.

Potatoes, ginger, and onions are not classified as true roots because they are modified plant structures. Potatoes are tubers, which are swollen underground stems that store energy. Ginger is a rhizome, a type of underground stem that grows horizontally and produces shoots and roots. Onions, on the other hand, are bulbs, which are storage organs consisting of a short stem surrounded by fleshy, modified leaves.
Tomato plants typically do not have swollen roots because their root system is designed for efficient nutrient and water uptake rather than storage. Unlike plants such as carrots or beets, which develop swollen roots for energy storage, tomatoes invest in a fibrous root system that supports their growth and fruit production. Swollen roots can also indicate issues like overwatering or root rot, which are detrimental to the plant's health. Thus, healthy tomato roots remain slender and functional rather than swollen.
The roots on the plants are swollen or thick
