Cytoplasm
B
Nucleus
C
Ribosomes
D
Plasma membrane
Verified step by step guidance1
Step 1: Begin by understanding the key differences between prokaryotic and eukaryotic cells. Prokaryotic cells are simpler and lack membrane-bound organelles, while eukaryotic cells are more complex and contain membrane-bound organelles such as the nucleus.
Step 2: Review the structures listed in the problem: cytoplasm, nucleus, ribosomes, and plasma membrane. Determine which of these structures are common to both prokaryotic and eukaryotic cells.
Step 3: Recall that cytoplasm is the gel-like substance within the cell where cellular processes occur, and it is present in both prokaryotic and eukaryotic cells.
Step 4: Understand that ribosomes are responsible for protein synthesis and are found in both prokaryotic and eukaryotic cells, although their structure may differ slightly.
Step 5: Note that the nucleus is a membrane-bound organelle that houses genetic material and is only found in eukaryotic cells. Prokaryotic cells lack a nucleus, as their genetic material is located in a region called the nucleoid. Therefore, the nucleus is the structure that is NOT found in both prokaryotic and eukaryotic cells.
