All amphipathic molecules, such as a phospholipid, have which of the following?

• Plasmodesmata

• A fluid mosaic model

• A hydrophobic and hydrophilic region

• A micelle configuration

What is the function of centrioles?

• They cause cytokinesis by the concentric shortening of microtubules.

• They produce microtubules for the chromosomes to migrate along as they move to opposite poles of the cell.

• They are required for DNA replication

• They enable bacteria to move

Which of the following is not a component of a cell wall?

• Peptidoglycans

• Cellulose

• Polysaccharides

• Glycogen

The movement of water out of a cell that results in the collapse of the cell is called

• plasmolysis

• dialysis

• facilitated diffusion

• simple diffusion

The movement of solutes against a gradient that requires an expenditure of energy is called

• Active transport

• Countercurrent exchange

• Simple diffusion

• Bulk flow
