What features of a single-celled organism enable them to carry on their life activites and maintain homeostasis?

Unicellular (one‐celled) organism is able to function despite lacking the levels of organization present in more complex organisms. Some single-celled organisms act in a manner similar to the tissues and systems found in multicellular organisms, thus enabling them to perform all of the life processes needed to maintain homeostasis. (ex. yeast, hydra, Euglena, etc.)

Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes.

Unicellurar organisms maintain relatively constant internal conditions, by growing, responding to the environment, transforming energy, and reproducing.

In biology, the term 'unicellular organisms' itself defines what type of living entities they are. They are single-celled organisms, wherein the functions like feeding, locomotion, expelling wastes, reproduction, etc. are carried out by the single cell.

In most cases, they are minute and require microscopes for viewing. In contrary to this, organisms consisting of more than one cell are known as multicellular organisms. All plants and animals which are viable with naked eyes are examples of multicellular types. Read more at Biologywise.com.
