Which of the following roots can mean "white"?

• A. "cyan/o" and "erythr/o"
• B. "erythr/o" and "leuk/o"
• C. "leuk/o" and "alb"
• D. "cyan/o" and "leuk/o"

Answer: (C)

The root "leuk/o" is derived from the Greek word "leukos," which specifically means "white." This root is commonly used in medical terminology to refer to white blood cells (leukocytes) and conditions associated with them, such as leukemia, which involves the production of abnormal white blood cells.

Additionally, "alb" is another root that means "white," originating from Latin. It is often used in terms like "albumin," referring to a family of proteins that are typically found in white substances.

Together, both "leuk/o" and "alb" clearly convey the meaning of "white," making this option the correct choice. Understanding these roots helps in deciphering medical terminology and provides context for various conditions and substances in the medical field.
