What are the structures that grow on potatoes and gingers?

You're asking about the structures that grow on potatoes and gingers, but you're using the wrong terms. Here's a breakdown:

* Potatoes: The "eyes" on potatoes are actually buds or nodes. These are the places where new shoots can emerge from the tuber (the underground stem that we eat).

* Gingers: The bumps or nodules on gingers are called rhizomes. Rhizomes are horizontal underground stems that produce roots and shoots. These are the part of the ginger plant that we eat.

So, to clarify:

* Potatoes: The structures are buds or nodes.

* Gingers: The structures are rhizomes.
