- 1. Multiple Choice
Compare the concentrations of the sugar in the cell and the solution. Which is HYPOTONIC?CellSolution - 2. Multiple ChoiceWhat do the following terms have in common?
-diffusion
-osmosis
-facilitated diffusionThey require energy to move materialsThey move from a low concentration to a high concentrationThey move move materials DOWN the concentration gradientThey require ATP - 3. Multiple ChoiceWhich direction will the dots (solute) move without the use of energy?into the cellout of the cell
- 4. Multiple ChoiceFacilitated diffusion is the movement of materials into and out of the cellwith the use of energywith the use of proteins but no energyby moving waterby using ATP
- 5. Multiple ChoiceThe movement of water from a high concentration to a low concentration is calleddiffusionosmosisfacilitated diffusionactive transport
- 6. Multiple ChoiceThe diagram represents a specialized cell located in the root of a plant. The arrows in the diagram indicate the movement of molecules of oxygen and water into the cell.
Which choice correctly identifies the process responsible for the movement of each type of molecule represented in the diagram?Water = diffusion
Oxygen = active transportWater = diffusion
Oxygen = diffusionWater = active transport
Oxygen = active transportWater = active transport
Oxygen = diffusion - 7. Multiple ChoiceWhich form of transport is being shown in the diagram.diffusionosmosisfacilitated diffusionactive transport
- 8. Multiple ChoiceThe water level increases on the right becausethere are less particles on the rightthere are more particles on the rightthe right side is hypotonicthe right side is isotonic
- 9. Multiple Choice
Which CELL contains MORE particles than are found in the surrounding solution?
Left
Center
Right
- 10. Multiple ChoiceWhen plant cells lose water to their environment the membrane collapses. This is calledreverse osmosisactive transportplasmolysisselectively permeability
- 11. Multiple ChoiceIn this situation, where the solute is illustrated by red dots, predict if will WATER move into or out of the cell, and how that will affect the cell.Water will move into the cell and the cell will expand.Water will move into the cell and the cell will shrink.Water will move out of the cell and the cell will expand.Water will move out of the cell and the cell will shrink.
- 12. Multiple Choice
Examine the diagram and determine, based on the concentrations of salt, if salt will move into or out of the cell.
INTO
OUT OF
- 13. Multiple ChoiceWhich illustration of transport across the membrane requires energy?ABCD
- 14. Multiple ChoiceSemi-permeable mean to allowall materials across the membraneonly some materials across the membraneno material to cross the membraneto allow only water across the membrane
- 15. Multiple ChoiceWhat factor DOES NOT influence whether or not a substance can pass through a membrane?sizechargenumber of atomsshape
