Textbook Question
Chapter 3, Problem 5CT
A researcher carefully inserts an electrode into an algal cell. He determines that the electrical charge across the cytoplasmic membrane is–70 millivolts. Then he slips the electrode deeper into the cell across another membrane and measures an electrical charge of –90 millivolts compared to the outside. What large organelle does the second membrane surround? Explain your answer.

Using the appropriate osmotic terms (hypertonic, hypotonic, or isotonic) describe what would happen to each organism in the following settings:
A single-celled freshwater protist is placed into a beaker of salt water.
A salt-water snail is mistakenly put into a freshwater tank.
A head of lettuce is placed soaked in a sink of salt water.
A carrot is soaked a sink of distilled, pure water.
You are using a computer program to design a new single-celled organism. Discuss why a flat, plate-like cell will be more efficient in transporting materials than a spherical, ball-like cell of the same volume.
