Modified stems have been altered by the parent plant to fit the needs of the plant. There are three examples I will be stating here.
First, there are the stolon. They grow horizontally along the ground and they grow above the ground. An example would be strawberries.
Next, there are the tuber stems. They are enlarged underground stems that are for starch storage. An example of this would be potatoes.
Finally, there are the succulent stems. They are fleshy and often leafless. They are used for water storage. An example would be cacti.
tuber. One example is a potato.
the correct answer is tuber...
Tuber.
Pomelo has a modified stem. It has spines.
The edible parts in a plant may be its fruits, seeds, roots or even leaves. In cereals we eat .grain, in the tuberous plants like potato, we eat the tuber (modified underground stem). That part of the plant which has storage of food is generally located to eat.
Onion is an underground modified stem.
Roots and stem get modified for storage or performing any specific function such as climbing or overcoming hostile environmental conditions. The basic difference between a root and stem is that in case of root, the primary vascular bundles are radial whereas in stems these are conjoint and collateral.
A portion of a root swells for food or water storage, e.g. sweet potato. A type of storage root distinct from taproot.
Tuber.

Tuber is the modified organ of the plant potato.
Onion is a modified stem because it is a stem which grows underground
roots modified for food storage
the roots
This type of modification of stem for storage of food is called bulb. The stem is extremely condensed in the form of a disc and is surrounded by fleshy scales. Since the scales (modified leaves) do not resort to photosynthesis, the bulb remains underground to overcome adverse atmospheric conditions of summers.

Stem cells that will form T cells are modified in the Thymus.
