Osmosis and Transport Quiz (WALA)

What is the diffusion of water?

• osmosis
• active transport
• diffusion
• facilitated diffusion

Which type of movement requires energy?

• osmosis
• active transport
• diffusion
• facilitated diffusion

Passive transport is called "passive" because it occurs WITHOUT

• cause.
• energy.
• a concentration gradient.
• a cell wall.

_____________ allows some things to enter and leave cells, while keeping other things out of the cell.

• Nucleus control center of the cell

• Selectively Permeable golgi apparatus

• A selectively permeable membrane
• Non Permeable membrane

When the concentration of solutes on both sides of a membrane is the SAME, the solution is

• hypertonic
• hypotonic

A process for removing large quantities toxins and waste from the cell is

• exorcism
• exocytosis
• endocytosis
• endoplasmic reticulum

A cell contains 25% NaCl and is placed in a solution that has 5% NaCl.  Which of the following is correct about what will happen to the cell?

• The solution is hypotonic and the cell will swell.
• The solution is hypotonic and the cell will shrink
• The solution is hypertonic and the cell will swell
• The solution is hypertonic and the celll will shrink.

An animal cell placed in a hypertonic (salty) solution will

• Shrink
• Swell
• Stay the same

A solution is considered hypertonic to the cell if it has....

• A higher amount of water compared to the cell.

• A higher amount of solute compared to the cell.

• A lower amount of solute compared to the cell.

Match the following

• The solution contains a high concentration of solute an and low concentration of water

• Isotonic

• The solution contains a low concentration of solute an and high concentration of water

• Hypotonic

• The solution has an equal concentration of solute and water compared to the inside of the cell

• Hypertonic
