Serum differs from blood in
- lacking globulins
- lacking albumins
- lacking clotting factors
- lacking antibodies
The Correct Option is C
Solution and Explanation
The correct answer is:
Option 3: lacking clotting factors
Explanation:
Option 1: lacking globulins: This is incorrect. Serum still contains globulins. Serum is essentially blood plasma without the clotting factors (such as fibrinogen), but it still contains globulins, which include antibodies.
Option 2: lacking albumins: This is incorrect. Serum contains albumins, which are the most abundant proteins in plasma and are important for maintaining osmotic pressure.
Option 3: lacking clotting factors: This is correct. The key difference between serum and plasma is that serum lacks the clotting factors (like fibrinogen), which are used up during the process of blood clotting. Plasma, on the other hand, contains these clotting factors.
Option 4: lacking antibodies: This is incorrect. Serum contains antibodies, which are a type of globulin protein. These antibodies are important for immune responses.
Summary:
The main difference between serum and blood (plasma) is that serum lacks clotting factors, making Option 3 the correct answer.

Concepts Used:
Blood
Blood is a fluid-like structure that is responsible for transporting oxygen and other nutrients to all the cells of the body. Blood shows characteristics of both tissues and fluid.
Composition of Blood:
Blood is composed of the below-mentioned parts:
- Plasma
- Blood Cells
- Platelets
Types of Blood Cells:
The two types of blood cells present in the body are:
RBC (Red Blood Cells)
RBC’s are also known as Erythrocytes. They are biconcave and are present without a nucleus in human beings. It contain Haemoglobin which is an iron-rich protein due to which the color of blood is red. RBC’s are produced in the bone marrow which is mainly responsible for the transportation of oxygen to and from various tissues and organs present in the human body.
WBC (White Blood Cells)
WBC’s are also known as Leucocytes which are colourless blood cells due to the absence of haemoglobin. They are further divided into two categories such as granulocytes and agranulocytes. Their main responsibility is to provide immunity and maintain defence mechanisms in the human body.
