To have more hemoglobin content as compared to the cells volume .

Mature red blood cells (RBCs) do not possess nucleus along with other cell organelles such as mitochondria, Golgi apparatus and endoplasmic reticulum in order to accommodate greater amount of haemoglobin in the cells. However, immature red blood cells contain nucleus.

Dear most of the major functions of the red blood cells are displayed in the cytoplasm where you can get the haemoglobin.

RBCs has a oxygen caring capacity via hemoglobin. It also allows the cell to have its distinctive bi-concave shape which aids diffusion - this shape would not be possible if the cell had a nucleus in the way. In some mammals ex. camel RBCs are nucleated.

The absence of a nucleus is an adaptation of the red blood cell for its role. It allows the red blood cell to contain more hemoglobin and, therefore, carry more oxygen molecules. It also allows the cell to have its distinctive bi-concave shape which aids diffusion. This shape would not be possible if the cell had a nucleus in the way.

Mature RBC lack nucleus to increase the haemoglobin which increases the oxygen transport as well as maintaining the bi-concave shape that help in easy diffusion in blood vessels.

Only RBCs don't have nucleus. All other types of blood cells have nucleus.  The nucleus is actually the control center of a cell. It has DNA in it which is required for reproduction of any cell. However, the function of RBCs is very simple. They just carry chemicals around. A RBC has haemoglobin in it which carries oxygen. The RBCs don't need to reproduce as simply more RBCs can be produced by the red bone marrow in a process called erythropoesis.

Nucleus takes up a lot of space in a cell and since RBCs don't actually do any of the functions which are nucleus's responsibility, evolution figured it out that it's more logical to just exclude them from the RBCs. This space can be used to fit in more haemoglobin.

RBC have to travel in small capillaries ,. It bi-concavity shape helps that and provide more area for gas exchange. It is not possible for nucleated cell.

Like so many, I am shocked and saddened at seeing war break out in Europe. My thoughts – and those of the ResearchGate team – are with the people of Ukraine and everyone affected.
ResearchGate is an international company, whose purpose is to enable scientists across the world to work together openly and collaboratively, regardless of borders or nationality. We have people from over 40 countries on our staff of around 200, and being based in Berlin, we are profoundly aware of the human cost of conflicts, the echoes of which have shaped and scarred our home city. We join with the international community in condemning the actions of the Russian state.
We have been asking ourselves: What can we do?
From today, we will offer free advertising space worth $2.5 million on our network to humanitarian organizations working to respond to the crisis. ResearchGate benefits from over 50 million visitors every month, and we hope this initiative can help raise funds and awareness for those organizations that are having direct impact and need support.
We also want to use our platform to highlight the response from the scientific community. Personally, I have found the messages of support from scientists everywhere to be truly heartfelt, and I would like to highlight some of the community initiatives I’ve seen here:
Additionally, I’m posting here some of the organizations responding to the crisis and actively soliciting donations:
To help gather more support for these initiatives, please consider sharing this post further (you don’t need a ResearchGate account to see it), and I will continue to update it with other initiatives as I find them. You can also click “Recommend” below to help others in your ResearchGate network see it. And if you know of any other community initiatives that we can share here please let us know via this form: https://forms.gle/e37EHouWXFLyhYE8A

The Concept of a cell membrane is traced back to the now-forgotten study of William Hewson, who in 1773 described osmotic effects on the shape of red blood corpuscles (RBC). The movement of the nucleus in osmotically swollen toad RBC suggested that RBC are vesicles with an elastic structure enveloping a fluid content.
