Answer 2

Hey.

Here is the answer.

The food is prepared in a plant in the green leaves by the process, which is called photosynthesis.

The process by which every green plants make food in the presence of sunlight using carbon dioxide and water is called photosynthesis.

Ginger and potato are underground stems; while Potato is a tuber, Ginger is a rhizome and the food is stored in them in the form of starch though it is prepared in the leaves. 

Due to the stored food in the stems, the underground stem swells and get bigger.

Thanks.
