Because they are unable to make repairs to themselves
Red blood cells lose their nucleus as they mature in order to make space for more hemoglobin, the protein that carries oxygen. Even without a nucleus, they are still considered cells because they have a cell membrane and other cellular components necessary for their function of transporting oxygen in the bloodstream.
Red blood cells are anucleate, meaning they do not have a nucleus. This lack of a nucleus allows them to have more space to carry oxygen and carbon dioxide efficiently.
Acellular, also known as anucleate. Acellular refers to cells that lack a nucleus, while anucleate specifically means without a nucleus.

They do. Mammals are the only vertebrates without a nucleus in their erythrocytes.
Red blood cells, also known as erythrocytes, are anucleate cells that transport oxygen to the body's cells. They contain hemoglobin, a protein that binds to oxygen in the lungs and releases it in tissues where it is needed.
Thenoticeabledifference is that bird erythrocytes have organelles and a nuclei, which most mammals erythrocytes don't have.
Anucleate means lacking a cell nucleus. Cells that are anucleate may contain other organelles but they do not have a nucleus, which is where genetic material is typically located. Examples of anucleate cells include red blood cells and platelets.
Anucleate means without a nucleus. Red blood cells are called anucleate because they don't have any nuclei.
anucleate
Erythrocytes, or red blood corpuscles, are indeed enucleate . . . that is, have no nuclei. They need the room for all the hemoglobin that they can carry. It also means that they can only live for about 120 days.
Yes, mature erythrocytes are still cells and are still living. In most mammals the circulating red blood cells do not have nuclei, so they are unable to repair themselves when damaged and eventually die due to the accumulated damage.
