A flexible membrane.
The cell membrane, also known as the plasma membrane, is the flexible barrier that encloses all the living material of an animal cell. It regulates the passage of substances in and out of the cell and helps maintain cell shape and integrity.

Growth occurs in all living things. Taking in material from the outside environment, a plant or animal creates material that becomes part of its own organism.
A cell is composed of living material called cytoplasm, which consists of water, proteins, lipids, nucleic acids, and various other organic molecules. These components work together to maintain the cell's structure and function.
This virus, which has a single strand of DNA enclosed in a protein capsule, is not considered a living organism. While it contains genetic material and can replicate, it requires a host cell to do so, lacking the cellular machinery necessary for independent life processes. Viruses are typically classified as acellular entities, existing at the boundary between living and non-living.
Viruses are typically composed of RNA surrounded by a capsid (protein shell). This would mean by definition that the virus molecule, which is technically considered nonliving, is larger than a protein strand (because the capsid is made of protein).
Growth is a characteristic of all living things that involves an increase in the amount of living material in an organism. This can occur through cell division, enlargement of cells, or accumulation of new cells.
A sponge is a porous aquatic animal that can absorb and filter water, while a rock is a solid mineral material formed naturally. Sponges are living organisms, while rocks are inanimate objects. Additionally, sponges have a soft and flexible texture, while rocks are hard and rigid.
No, viruses are not living organisms and do not require oxygen to survive. They are simply comprised of genetic material (DNA or RNA) enclosed within a protein coat, and they rely on host cells to reproduce.
It keeps it flexible and living by all the voting.
