1) Their ability to ferry O2 through Blood and 2) the are devoid of a Cell nucleus.
Hemoglobin gives the red blood cells the ability to carry oxygen.
blood
Red blood cells.
Hemoglobin carries the oxygen in the blood and it gives the red blood cells their color.
Pluripotent haematopoietic stem cells are the precusor/progenitor cells of all blood cells.
the lung is where the hemoglobin take up the oxygen and the blood cells re-oxygenate
Haemoglobin. That's what gives red blood cells their colour, too.
Gametocytes.
Any cell from your body, which have the nucleus, will do for genetic material. So you can collect the blood, which have white blood cells, will do. Biopsy from any part gives you enough cells for the genetic material, you need for genetic testing.
No, white blood cells do not contain hemoglobin; red blood cells contain hemoglobin (and it is the hemoglobin that gives them their red color).
The skeleton give structure to the body as well as protects organs and parts of it make red blood cells, platelets and white blood cells.
