Cell Transport and Plants Review

Match the following

• main component of the cell membrane

• active transport

• some substances can go through the cell membrane and some can't

• membrane proteins

• requires ATP; molecules move low to high

• passive transport

• allows large molecules to pass through membrane

• semipermeable

• does not require ATP; molecules move high to low

• phospholipids

Match the following

• When molecules passively cross the plasma membrane through the phospholipid bilayer

• Simple Diffusion

• Bringing in large materials through the cell membrane into a vacuole.

• Facilitated Diffusion

• Moving larger amounts or large quantities of materials through the cell membrane

• Endocytosis

• When molecules passively cross the plasma membrane through a channel protein

• Exocytosis

• The movement of water across the cell membrane

• Osmosis

Match the following

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

• Isotonic

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

• Hypertonic

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

• Hypotonic

In 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.

Semi-permeable mean to allow

• all materials across the membrane
• only some materials across the membrane
• no material to cross the membrane
• to allow only water across the membrane

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

• isotonic
• hypertonic
• hypotonic

Facilitated diffusion involves movement of molecules across a membrane when they bond to 

• channel proteins
• lipid proteins
• a protein pump (carrier protein)
• sticky proteins

If there is 25% oxygen inside the cell and 50% oxygen in the outside blood, which direction will the oxygen move?

• Out of the cell
• Into the cell
• The cell is at equilibrium

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.

In the given scenario what will happen to the organism: salt is poured onto eggplant.

• Water will move out of the eggplant cells and the cells will shrink.
• Water will move out of the eggplant cells and the cells will swell.
• Water will move into the eggplant cells and the cells will swell.
