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.

ginger , turmeric, potato are different examples of underground stem buds.
Potatoes have underground stems called tubers that have eyes where new shoots can sprout, leading to the growth of new potato plants.
Onions are classified as modified stems (bulbs) and primarily store nutrients rather than perform photosynthesis. As a result, they lack chloroplasts, which are the organelles responsible for photosynthesis and are typically found in green, photosynthetic tissues of plants. Since onions grow underground and do not rely on light for energy, they do not develop chloroplasts like green leafy plants do.
Onions do not contain chloroplasts because they do not perform photosynthesis. Instead, onions rely on obtaining nutrients from the soil to grow and sustain themselves. chloroplasts are found in plant cells that undergo photosynthesis to produce energy for the plant.
Two underground storage stems used as food are tubers and rhizomes. Tubers are thickened, fleshy underground stems like potatoes, while rhizomes are horizontal underground stems like ginger that grow beneath the surface.
