Note that not all blood cells are red; there are also white blood cells. Red blood cells contain a chemical called hemoglobin, and hemoglobin includes an iron atom, and when the iron atom has an oxygen molecule loosely attached to it (by a coordinate covalent bond) it will have a red color (for a deeper explanation it is necessary to examine the structure of the electron orbitals in the iron atom).
The content of oxygen within the RBC's.
NO, they do not look the same !
Red blood cells all look like red blood cells. White cells have different shapes mainly because they have different functions.
Red blood cells contain hemoglobin. These cells are also known as erythrocytes.
Red blood cells, which look like little disks , carry oxygen from the lungs to all body parts.
As the name says, red blood cells are found in the blood. If there is blood there, there is red blood cells.
A light microscope would typically be used to look at a blood sample. This type of microscope has sufficient magnification and resolution to visualize blood cells such as red blood cells, white blood cells, and platelets.
The cells in the bloodstream include red blood cells, white blood cells, and platelets. Red blood cells carry oxygen to tissues, white blood cells help fight infections, and platelets aid in blood clotting.

Red blood cells because that is what carries oxygen throughout the body
White blood cells have a nucleus and red blood cells don't.
