Thallus is a term used in biology to describe a simple plant body that lacks specialized structures such as roots, stems, and leaves. It is a term often used to describe the body of organisms such as algae, lichens, and fungi that do not have a well-differentiated plant structure.

The thallus can vary in shape, size, and complexity, depending on the organism it belongs to. It is an important adaptation for survival in environments where specialized structures are not necessary or would be a hindrance to the organism's survival.
