Red blood cells all look like red blood cells. White cells have different shapes mainly because they have different functions.

Frogs have nucleated red blood cells, whereas humans have anucleated red blood cells. This means that frog red blood cells contain a nucleus, while human red blood cells do not. Additionally, frog red blood cells are elliptical in shape, while human red blood cells are biconcave disks.
white and red blood cells have 2 different shapes because they have 2 different functions in the body.
Irregularly shaped red blood cells are known as poikilocytes and can indicate certain medical conditions such as sickle cell anemia or vitamin deficiencies. These irregular shapes can affect the ability of the red blood cells to carry oxygen efficiently throughout the body.
Red blood cells contain hemoglobin. These cells are also known as erythrocytes.
As the name says, red blood cells are found in the blood. If there is blood there, there is red blood cells.
Red blood cells (erythrocytes) and white blood cells (leukocytes) are very different. Red blood cells are round, lack a nucleus and function to carry oxygen throughout the body. White blood cells can be many different shapes, have a nucleus and function to detect and destroy invading pathogens.
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.
