Starch turns blue-black in the presence of iodine solution. A selectively permeable dialysis sac containing a starch solution is placed into a beaker of iodine solution. If the dialysis sac is permeable ONLY to water and iodine, what will the solutions in the beaker and the sac look like after two hours?

• The iodine solution in the beaker will turn blue-black; the starch solution will not change

• The starch solution in the dialysis sac will turn blue-black; the iodine solution will not change

• Neither solution will turn blue-black

• Both solutions will turn blue-black

What conditions cause the contractile vacuole to fill with water?

• The concentration of water is greater outside the cell than inside the cell

• The Temperature of water in the vacuole is higher than the temperature of its environment

• The concentration of water inside the cell is the same as the concentration outside the cell

• The temperature of water in the vacuole is lower than the temperature of its environment

The diagram shows the same type of molecules in area A and area B. With the passage of time, some molecules move from area A to area B. This movement is a result of the process of -

• Diffusion

• Facilitated diffusion

• Active transport

• Cytokinesis

The diagram below illustrates how plant root cells take in mineral ions from the surrounding soil. What type of transport is this?

• Active Transport

• Diffusion

• Osmosis

• Passive Filtration

The arrows, in the diagram below, represent the direction of movement of solutes through the cell membrane of two different cells, Cell A and Cell B. The dots represent the concentration of the solutes. Cell B shows the process of (a)   . This is because molecules are moving from an area of High concentration to an area of Low concentration.

• Osmosis

• Diffusion
• Active Transport

• Facilitated Diffusion

The table below lists the concentrations of water inside and outside a cell under four different conditions. Under which condition will the cell experience a loss of water to its environment?

• 90% in cell, 95% in environment

• 90% in cell, 100% in environment

• 95% in cell, 90% in environment

• 95% in cell, 95% in environment

Which statement best describes the role of the cell membrane in this model?

• The cell membrane is an impermeable barrier that prevents water from entering the cell

• The cell membrane allows solutes to enter the cell, which causes the cell to shrink

• The cell membrane allows water to enter and leave the cell

• The cell membrane removes solutes from the environment.
