Question

which cell structure serves the stated function in both eukaryotic and prokaryotic cells?
○ nucleus: stores genetic material
○ cytoplasm: protects cell structures
○ ribosomes: regulate cell processes
○ dna: surrounds cell contents

Explanation:

1. Analyze the first option: Prokaryotic cells do not have a nucleus (they have a nucleoid region), so the nucleus can't store genetic material in prokaryotes. Eliminate this option.
2. Analyze the second option: Cytoplasm is the gel - like substance within the cell that holds and protects cell structures (like organelles in eukaryotes and components in prokaryotes) in both eukaryotic and prokaryotic cells.
3. Analyze the third option: Ribosomes are responsible for protein synthesis, not regulating cell processes. Cell processes are regulated by various factors like enzymes, signaling molecules, etc. Eliminate this option.
4. Analyze the fourth option: DNA is the genetic material, it does not surround cell contents. The cell membrane (or plasma membrane) surrounds cell contents. Eliminate this option.

Answer:

B. cytoplasm: protects cell structures
