Verified step by step guidance1
Understand that blood is composed of several components, including red blood cells, white blood cells, platelets, and plasma.
Recognize that the red color of blood is primarily due to the presence of hemoglobin in red blood cells.
Learn that hemoglobin is a protein that binds oxygen and contains iron, which gives it a red color when oxygenated.
Differentiate between the components listed: Platelets are involved in clotting, plasma is the liquid portion of blood, and white blood cells are part of the immune system.
Conclude that hemoglobin, found in red blood cells, is responsible for the red color of blood due to its iron content and oxygen-binding properties.
