Which of the following statements about protoplasm of a cell is not correct? It

Step 1: Analyze the question We are asked to find the statement about protoplasm that is not correct. The question is a "negative" one, so three options are true and one is false.

Step 2: Concept Protoplasm is the living content of a cell. It includes:

• The cytoplasm, the jelly-like material, including the cell organelles such as mitochondria, ribosomes and the Golgi apparatus
• The nucleus, which is the control center of the cell
• (Some texts also include the cell membrane)

So protoplasm = cytoplasm + nucleus, with the organelles included.

Step 3: Check each option

• A. Comprises of the nucleus. Correct, because the nucleus is part of protoplasm.
• B. Consists of the cytoplasm. Correct, because cytoplasm is a major part of protoplasm.
• C. Comprises of the cell organelles. Correct, because the organelles are found within the protoplasm.
• D. Consists the nucleus only. Incorrect. Protoplasm is not limited to the nucleus. It also includes the cytoplasm and the organelles.

Step 4: Answer The statement that is not correct is D.

Exam tip: In "which is NOT correct" questions, mark each option True or False first. Watch for words like "only", "all" and "always", which often make a statement false. Remember: Protoplasm = Nucleus + Cytoplasm (with organelles).
