(19 cards)
What is the primary function of the prokaryotic cell membrane?
The primary function of the prokaryotic cell membrane is to act as a selective barrier that regulates the entry and exit of substances.
True or False: Prokaryotic cells have a nucleus.
False: Prokaryotic cells do not have a nucleus.
Fill in the blank: The _____ is a rigid structure that provides shape and protection to prokaryotic cells.
cell wall
What structure is responsible for protein synthesis in prokaryotic cells?
Ribosomes are responsible for protein synthesis in prokaryotic cells.
Which prokaryotic structure is involved in locomotion?
Flagella are involved in locomotion.
Multiple Choice: Which of the following is NOT a function of the prokaryotic plasma membrane? A) Energy production B) Protein synthesis C) Transport regulation D) Structural support
D) Structural support
What is the role of the nucleoid in prokaryotic cells?
The nucleoid contains the cell’s genetic material (DNA).
True or False: Plasmids are essential for the survival of prokaryotic cells.
False: Plasmids are not essential but can provide advantages such as antibiotic resistance.
Fill in the blank: Prokaryotic cells reproduce through a process called _____.
binary fission
What is the function of the capsule in prokaryotic cells?
The capsule protects the cell from desiccation and helps in evading the immune system.
Which structure in prokaryotic cells helps in adherence to surfaces?
Pili help in adherence to surfaces.
Multiple Choice: Which of the following structures is involved in the transport of molecules across the cell membrane? A) Ribosome B) Cytoplasm C) Transport proteins D) Nucleoid
C) Transport proteins
What is the function of the cytoplasm in prokaryotic cells?
The cytoplasm is the site of metabolic processes and contains the organelles.
True or False: Prokaryotic cells can have complex internal structures.
False: Prokaryotic cells typically have simpler internal structures compared to eukaryotic cells.
Fill in the blank: The _____ is a gel-like substance inside the prokaryotic cell where organelles are suspended.
cytosol
What is the role of the ribosome in prokaryotic cells?
Ribosomes are responsible for translating messenger RNA into proteins.
Multiple Choice: Which structure helps prokaryotic cells to exchange genetic material during conjugation? A) Cell wall B) Flagella C) Pili D) Nucleoid
C) Pili
What is the significance of the peptidoglycan layer in prokaryotic cells?
The peptidoglycan layer provides structural support and rigidity to the cell wall.
True or False: All prokaryotic cells have a capsule.
False: Not all prokaryotic cells have a capsule.
