Answer:
Sponge consists of cellulose that absorbs water or any other fluid and retain it in itself until unless it is squeezed.
Explanation:
Artificial sponges are made up of cellulose extracted from plants and trees. They work exactly the same way a natural sponge work by absorbing any fluid and then expanding to store the absorbed fluid which is not allowed to flow back until unless it is squeezed. An artificial cellulose is made up of cellulose, sodium sulphate and hemp fiber.
