yes. a bconcave disc withpout a nucleas is called as erythrocytes. there biconcave nature helps them to carry more haemoglobin and hence the can transport more gases.
Biconcave cells without nuclei are called red blood cells.
Erythrocyte
A red blood cell that (in humans) is typically a biconcave disc without a nucleus. Erythrocytes contain the pigment hemoglobin, which imparts the red color to blood, and transport oxygen and carbon dioxide to and from the tissues.
Mammalian RBC is always enucleated [Without nucleus] without any EXCEPTION The mammalian RBC is also biconcave and DISCOIDAL except Camel and Llama, which have Oval shaped RBC
The importance of hemoglobin for erythrocyte function is that it gives them oxygen carrying abilities. Without hemoglobin, the erythrocyte would be unable to carry and transport oxygen where it needs to go.
The human red blood cell lacks a nucleus, and its shape is biconcave (to allow higher oxygen uptake and to flow through the vessels without hooking onto junctions)
it is nucleus
Every cell has a nucleus. Without a nucleus there is no DNA in the cell and if you didn't know the nucleus is the brain of the cell.
Some unicellular organisms get by fine with no nucleus. The general term for these is prokaryotes. (A few prokaryotes form multicelluar stages, but this is not common.) Most multicellular organisms... and some unicellular organisms... do have cell nuclei. The general term for these is eukaryotes. Some specialized cells in multicellular organisms have no nucleus. For example, mammalian red blood cells have no nucleus. The generic term for any cell without a nucleus, whether a prokaryote or a specialized cell in a eukaryote, is anucleate (which simply means "without a nucleus").
because eukaryotic have a nucleus
There would not be a cell without a nucleus it is like saying what if a human without a brain. It is impossible.
no, a cell can't survive without its nucleus as nucleus is the main brain of the cell. *****A red blood cell is without a nucleus and can survive for 120 days. This cell is very unique to the body because of this.
