Answer:
- W is potato
- X is iodine solution
- Y is blue black color
- Z is starch i.e carbohydrate.
Explanation:
- A potato is a tuber, which is an underground modification of a stem. The tuber is the branch of the main stem which accumulates food in it and swells up.
- Numerous axillary buds, also known as eyes, are developed on the surface of the tuber and are capable of developing into the new plant under favorable conditions.
- To determine the presence of starch in potatoes, an Iodine test is done using an Iodine solution.
- When the iodine solution is added to the surface of the potato, it turns blue-black.
- The presence of a blue color indicates the presence of starch, a type of carbohydrate.
