Question

practice: putting it all together
part 1: fill in the blank

1. what property of the cell membrane allows some molecules to pass easily through, but not all? ____
2. because the cell membrane is made of 2 layers of lipids it is called a ____
3. what is the transport of water across the cell membrane called? ____
4. transport that moves materials against the concentration gradient is said to be ____

part 2: analyze the pictures
in numbers 5 - 7, label the type of transport pictured, add arrows to the picture to show movement, and write a sentence describing what will happen to the cell.

1. type of transport ____

description ____

part 3: matching

1. used in active transport but not passive transport a protein channel
2. process of taking in materials using a vesicle b hypotonic
3. solution that causes water to rush out of the cell c isotonic
4. can be used in both active and passive transport d hypertonic
5. process of removing substances from the cell using a vesicle e molecular pumps
6. when the osmotic concentration is the same inside and outside of the cell f exocytosis
7. solution that causes a cell to swell and potentially lyse (burst) g endocytosis
8. transport of ions across the cell membrane h energy
