Why is a Potato a Stem and Not a Root Despite Growing Underground?

Final Answer:

A potato is classified as a stem and not a root despite growing underground because it possesses characteristics typical of stems, such as nodes and internodes, buds or eyes, vascular bundles, and apical dominance.

Explanation:

Potatoes are classified as stems because they possess characteristics that are typical of stems. Stems are plant organs that provide support, transport water and nutrients, and produce leaves and flowers. Despite growing underground, potatoes exhibit several features that differentiate them from roots.

Firstly, potatoes have nodes and internodes, which are characteristic of stems. Nodes are the points on the stem where leaves, branches, or buds emerge, while internodes are the spaces between the nodes.

Secondly, potatoes have buds or eyes, which are potential growth points for new shoots. These buds are also found on stems.

Additionally, potatoes have vascular bundles, which are responsible for transporting water, nutrients, and sugars throughout the plant. These vascular bundles are typically found in stems.

Lastly, potatoes undergo a process called apical dominance, where the growth of lateral branches is inhibited by the dominant apical bud. This is a characteristic of stems.

Overall, these characteristics classify potatoes as stems rather than roots.
