Which characteristic is missing on the poster?
A.Prokaryotic cells do not have a nucleus and eukaryotic cells have a nucleus.
B.Prokaryotic cells do not have cytoplasm and eukaryotic cells have cytoplasm.
C.Prokaryotic cells do not have ribosomes and eukaryotic cells have ribosomes.
D.Prokaryotic cells do not have cell membrane and eukaryotic cells have a cell mebrane
D.Prokaryotic cells do not have cell membrane and eukaryotic cells have a cell mebrane
To determine which characteristic is missing on the poster, let's analyze each option one by one:
A. Prokaryotic cells do not have a nucleus and eukaryotic cells have a nucleus: This statement is correct and is commonly observed in textbooks and scientific literature. Prokaryotic cells lack a nucleus, while eukaryotic cells have a well-defined nucleus that houses the genetic material.
B. Prokaryotic cells do not have cytoplasm and eukaryotic cells have cytoplasm: This statement is incorrect. Both prokaryotic and eukaryotic cells have cytoplasm. Cytoplasm refers to the gel-like substance that fills the cell and contains various organelles.
C. Prokaryotic cells do not have ribosomes and eukaryotic cells have ribosomes: This statement is incorrect. Both prokaryotic and eukaryotic cells have ribosomes. Ribosomes are responsible for protein synthesis and are present in all types of cells.
D. Prokaryotic cells do not have a cell membrane, and eukaryotic cells have a cell membrane: This statement is incorrect. Both prokaryotic and eukaryotic cells have a cell membrane. The cell membrane acts as a protective barrier and regulates the transport of molecules in and out of the cell.
Based on this analysis, the correct characteristic missing on the poster would be option B. Prokaryotic cells do not have cytoplasm and eukaryotic cells have cytoplasm.
