The cytoplasm of a cell is considered a very important component because it

Step 1: Analyze the question The question asks why the cytoplasm is important to a cell. We need the statement that correctly describes its role.

Step 2: Explain the concept The cytoplasm is the jelly-like substance (cytosol) between the cell membrane and the nucleus. It is mostly water, with dissolved salts, sugars, amino acids and proteins. Its main functions are:

• It holds and supports the organelles (mitochondria, ribosomes, endoplasmic reticulum, etc.) by suspending them in place.
• It is the site of many chemical reactions, such as glycolysis.
• It allows materials to be moved and dissolved around the cell.

Step 3: Evaluate each option

• A. Regulates the amount of energy in the cell: Incorrect. Energy production is mainly done by the mitochondria, and the cytoplasm does not regulate energy levels.
• B. Suspends all cell organelles: Correct. The cytoplasm is the medium in which all the organelles are held.
• C. Is the outermost part of the cell: Incorrect. The outermost part is the cell membrane (and the cell wall in plant cells).
• D. Is solely responsible for cell division: Incorrect. Cell division involves the nucleus, chromosomes and spindle fibres. The word "solely" makes this option wrong.

Step 4: Answer

Tip: In JAMB, watch out for absolute words like "solely", "only" and "all" in options. They often signal a wrong answer. Here "all" in B is acceptable because it is a true description of cytoplasm. Remember: cytoplasm = the cell's "suspension medium".
