Question

Identify the INCORRECT statement about blood plasma.

• A. It is a straw colored, slightly alkaline and viscous fluid.
• B. It contains 90% of water.
• C. It contains proteins like albumin, globulin, prothrombin etc.
• D. It also contains regulators like stroma and nucleus.

Hint:

Plasma is the fluid part of blood and contains dissolved substances, not cell parts like nucleus.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
Plasma is the straw-coloured, slightly alkaline and viscous fluid part of blood. It is about 90-92 percent water.

Step 2: Check the statements
Plasma proteins are albumin, globulin, prothrombin and fibrinogen, so the third statement is correct.

Step 3: Find the wrong statement
Stroma and nucleus are parts of cells, not dissolved substances in plasma. The regulators in plasma are hormones and enzymes.

Final Answer:
The statement that plasma contains stroma and nucleus as regulators is incorrect. \[ \boxed{\text{(D) }\text{It also contains regulators like stroma and nucleus.}} \]
