Red Blood Cells
Red blood cells are also called erythrocytes.














What are the organelles found in the cell?
A plasma membrane and hemoglobin are found in red blood cells.

List the structural features of the cell.
They are biconcave discs, having a depressed center on both sides. These depressed centers allow the cells to have more cell membrane surface which can be exposed to diffusing oxygen while transiting the lungs. This structure also allows them to be more flexible with the ability to twist and bend through the blood vessels.

What are the functions of these organelles?
Red blood cells carry oxygen to all the tissues from the lungs. The red blood cells then transport the carbon dioxide from the tissues back to the lungs.

Why are these functions of the organelles important to the living cell?
The red blood cells carry oxygen to parts of our body. This enables us to carry out life processes. If oxygen is not transported around our body, we will lack of oxygen and die.

  11. Now I know that the red blood cell depressed center on either side is to allow the cells to have more cell membrane surface which can be exposed to diffusing oxygen while transiting the lungs.
