3.2.1.2 Structure of prokaryotic cells and viruses Flashcards
Q: How do the sizes of prokaryotic cells compare to eukaryotic cells?
A: Prokaryotic cells are much smaller than eukaryotic cells.
Q: What type of organelles do prokaryotic cells lack in their cytoplasm?
A: Prokaryotic cells lack membrane-bound organelles in their cytoplasm.
Q: What size are the ribosomes in prokaryotic cells compared to those in eukaryotic cells?
A: Prokaryotic cells have smaller ribosomes than eukaryotic cells.
Q: What is the composition of the cell wall in prokaryotic cells?
A: The cell wall in prokaryotic cells contains murein, which is a glycoprotein.
Q: What type of genetic material do prokaryotic cells have, and where is it located?
A: Prokaryotic cells have a single circular DNA molecule that is free in the cytoplasm and is not associated with proteins.
Q: What additional structures might be present in many prokaryotic cells?
A: Many prokaryotic cells may have one or more plasmids, a capsule surrounding the cell, and one or more flagella.
Q: What is the nature of viruses in terms of cellular structure and life status?
A: Viruses are acellular and non-living.
Q: What are the main structural components of a virus particle?
A: A virus particle consists of genetic material, a capsid, and attachment proteins.
