prokaryotic and eukaryotic structures Flashcards
What are prokaryotic cells?
Prokaryotic cells are simple, small cells without a nucleus. Examples include bacteria.
What is the nucleoid in a prokaryotic cell?
The nucleoid is where the DNA is located in a prokaryotic cell. It is not in a nucleus and is naked (not attached to proteins).
What is the function of the cell wall in prokaryotes?
The cell wall keeps the shape of the cell and prevents it from bursting.
What is a key feature of prokaryotic DNA?
Prokaryotic DNA is circular and naked (not attached to proteins).
What is the ribosome size in prokaryotes?
Prokaryotes have 70S ribosomes.
How is a prokaryotic cell different from a eukaryotic cell?
Prokaryotic cells are simpler, have no nucleus, and their DNA is circular. Eukaryotic cells have a nucleus and linear DNA.
What is a nucleus in eukaryotic cells?
The nucleus is a membrane-bound organelle that contains the DNA in eukaryotic cells.
What is the function of mitochondria in eukaryotic cells?
Mitochondria produce energy through aerobic respiration.
What is the key difference between ribosomes in prokaryotes and eukaryotes?
Prokaryotic ribosomes are 70S, while eukaryotic ribosomes are 80S.
What is the internal structure of eukaryotic cells like?
Eukaryotic cells have compartments (organelles) with specific functions.
What is the function of the cell membrane?
The cell membrane controls what enters and exits the cell, keeping the cell safe.
