The ability of a solution to cause a cell within it to gain or lose water. turgor. when a plan cell is placed in a hypotonic solution water moves in to the cell and to the central vacuole the cell's protoplast expands. The cell wall restricts expansion resulting in tugor pressure. diffusion. when molecules move from high concentration to low concentration.
For other uses, see Anemia (disambiguation). Anemia, also spelled anaemia, is usually defined as a decrease in the total amount of red blood cells (RBCs) or hemoglobin in the blood. It can also be defined as a lowered ability of the blood to carry oxygen.
Anemia (AmE) or anaemia (BrE), from the Greek (á¼Î½Î±Î¹Î¼Î¯Î±) meaning without blood, refers to a deficiency of red blood cells (RBCs) and/or hemoglobin. This results in a reduced ability of blood to transfer oxygen to the tissues, causing hypoxia.ne red blood cell contains about 200 million hemoglobin molecules. If all this hemoglobin was in the plasma rather than inside the cells, blood would be so thick that the heart would have a difficult time pumping it through. The thickness of blood is called viscosity.
