6. The Membrane

Which type of solution would most likely cause a plant cell placed in it to become firmer and more rigid?

Which process describes the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration?

Which term describes the movement of water downward through the soil due to gravity?

If a hypotonic solution surrounds a cell, water will ___.

Why does water move into the root hairs of a plant during osmosis?

What is the term for the movement of water across a cell membrane?

Which of the following characteristics most directly affects the diffusion of oxygen into the icefish’s blood?

A selectively permeable membrane separates two solutions. Water is able to pass through this membrane; however, sucrose (a disaccharide) and glucose (a monosaccharide) cannot pass. The membrane separates a 0.2-molar sucrose solution from a 0.2-molar glucose solution. With time, how will the solutions change?

The internal solute concentration of a plant cell is about 0.8 M. To demonstrate plasmolysis, it would be necessary to suspend the cell in what solution?

A single plant cell is placed in an isotonic solution. Salt is then added to the solution. Which of the following would occur as a result of the salt addition?

Seawater is hypertonic to cytoplasm in vertebrate cells and in plant cells. If a red blood cell and a plant cell were placed in seawater, what would happen to the two types of cells?
