Why potato ginger turmeric yam onion are thick fleshy and bulging?

Potato, ginger, turmeric, yam, and onion are all examples of storage organs in plants. These organs are specialized for storing nutrients and water, which allows plants to survive through periods of stress or unfavorable conditions, such as winter or drought. The thickness, fleshiness, and bulging shape of these organs are all adaptations that help them to store and protect their nutrients.

* Thickness: The thick flesh of these organs provides a large surface area for the storage of nutrients. This allows the plant to store a significant amount of energy in a relatively small space.

* Fleshy: The fleshy texture of these organs is due to the high water content. Water is essential for many cellular processes, and it also helps to protect the nutrients stored in the organs from damage.

* Bulging shape: The bulging shape of these organs helps to protect them from physical damage. The rounded shape helps to distribute pressure evenly, and the thick flesh helps to absorb impacts.

In addition to these morphological adaptations, these organs also contain a variety of biochemical adaptations that help them to store nutrients and protect them from degradation. For example, potatoes contain a high concentration of starch, which is a complex carbohydrate that is easily stored and broken down for energy. Ginger, turmeric, and yam contain a variety of antioxidants that help to protect their nutrients from damage by free radicals. Onions contain a variety of sulfur compounds that give them their characteristic flavor and odor, and these compounds also help to protect the nutrients stored in the onion from degradation.

The combination of morphological and biochemical adaptations allows these storage organs to store nutrients and water efficiently and protect them from damage. This is essential for the survival of the plant during periods of stress or unfavorable conditions.
