Sponges have the ability to regenerate damaged parts of their bodies a) true b) false plzz

They can be cut up or mashed, and as long as they have two special cells called collencytes, which produce the gelatinous matrix in the sponge, and archeocytes, which produce all the other cells in the spongeâ??s body, the sponge will reform into the sponge it once was. Although, it will look different. Hope it helps!
