Why would the potato contain starch?

Here's why:

* Starch is a complex carbohydrate: This means it's made up of many sugar molecules linked together, which makes it a very efficient way to store energy.

* Plants need energy: Just like animals, plants need energy to grow, reproduce, and carry out their essential functions.

* Potatoes are underground storage organs: The potato tuber (the part we eat) is designed to store energy for the plant. This energy will be used for future growth, flowering, and seed production.

So, the starch in potatoes is a vital part of the plant's life cycle, allowing it to survive and thrive.
