Is it for the plant to store energy and we just simply evolved to take advantage of that?
In: Biology
Carrots and potatoes are for energy storage over the winter. Carrots, beets, turnips, and many other root vegetables are biennial. Their natural cycle is to live for two years. Year 1 they grow and store energy, then frost kills the above ground part. Year 2 they grow quickly from stored resources, capture solar energy, and put it into seed production.
Potatoes aren’t strictly biennnial, because they can grow back from roots multiple years, but the idea is the same. They store energy in year one, and produce seeds in the following years.
