Question

12 multiple choice 2 points what is the function of flagella in prokaryotic cells? protein synthesis reproduction protection movement 13 multiple choice 2 points what is the role of pili in prokaryotic cells? locomotion protein synthesis protection interaction between cells 14 multiple choice 2 points what is the role of carbohydrates in the plasma membrane? to form a bilayer maintain fluidity transport cell to cell recognition

Explanation:

1. Flagella in prokaryotic cells are long, whip - like structures that enable the cell to move. Protein synthesis occurs at ribosomes, reproduction is related to genetic material replication, and protection is mainly by the cell wall or capsule.
2. Pili in prokaryotic cells are used for cell - to - cell interaction such as conjugation, not for locomotion (flagella do that), protein synthesis, or protection.
3. Carbohydrates in the plasma membrane are mainly involved in cell - to - cell recognition. Phospholipids form the bilayer, cholesterol helps maintain fluidity, and transport is mainly by proteins.

Answer:

1. D. movement
2. D. interaction between cells
3. D. cell to cell recognition
