Self Quiz for Eukaryotic Cell Structure: The Cytoplasmic Membrane

Study the material in this section and then write out the answers to these questions.
Do not just click on the answers and write them out. This will not test your understanding of this tutorial.

1. Match the following descriptions with the best answer.

_____ The movement of water across a membrane from an area of higher water concentration (lower solute concentration) to lower water concentration (higher solute concentration). (ans)

_____ The net movement of gases or small uncharge polar molecules across a phospholipid bilayer membrane from an area of higher concentration to an area of lower concentration. No metabolic energy is required. (ans)

_____ A transport where the cell uses transport proteins such as antiporters or symporters and metabolic energy to transport substances across the membrane against the concentration gradient. (ans)

_____ If the net flow of water is out of a cell, the cell is in ________________ environment. (ans)

_____ If the net flow of water is into a cell, the cell is in ________________ environment. (ans)

_____ The ingestion of dissolved materials by endocytosis whereby the cytoplasmic membrane invaginates and pinches off placing small droplets of fluid in a vesicle. (ans)

_____ The process by which a cell releases waste products or specific secretion products by the fusion of a vesicle with the cytoplasmic membrane. (ans)

A. active transport
B. passive diffusion
C. osmosis
D. exocytosis
E. pinocytosis
F. phagocytosis
G. a hypotonic
H. a hypertonic
I. an isotonic
