What kind of vegetables are cassava yams and sweet potatoes?

Let's break down the classifications of cassava, yams, and sweet potatoes:

* Cassava: This is a root vegetable, also known as tapioca. It's a starchy tuber, not a true yam.

* Yams: These are true yams, classified as tubers and belonging to the *Dioscorea* genus. They're starchy and often have a brown, rough skin.

* Sweet potatoes: These are root vegetables, classified as tubers but are part of the *Ipomoea* genus. They have a sweet, slightly starchy flavor and are often orange or white in color.

In summary:

* Cassava and sweet potatoes are root vegetables that are commonly consumed as tubers.

* Yams are true yams, a distinct type of tuber with a different botanical classification.

It's important to note that the term "yam" is often used incorrectly in some parts of the world to refer to sweet potatoes. While they share similarities in being starchy tubers, they are separate botanical species.
