Unit 3 Test Corrections

Unit 3 Test Corrections
These are the most missed questions from your class. Please read the informational slides and complete the questions that follow. I will add points back to your test grade based on your completion and effort on this assignment.

9. Which type of passive transport involves
proteins to move materials across the cell
membrane?

There are three types of passive transport.
None of them require energy and they are all
driven by balance.

Look at the next slide to see the differences
between the three types, then try question 9
again.

Test question number 9

Multiple Choice

Which type of passive transport involves proteins to move materials across the cell membrane?

• Osmosis

• Facilitated Diffusion

• Simple Diffusion

• Endocytosis

This question asked you to distinguish between
oxygen, glucose, and sodium, then to decide
how they cross the membrane using pictures.

Look at the next several slides to remind yourself
how these molecules move across the
membrane, then try question 5 again.

Make sure you look at the key and at the
direction of the arrows when you try the
question again.

Test question number 5

Labelling

Label the cell membrane with the correct transport mechanism according to the type of molecule moving across the membrane.

Drag labels to their correct position on the image

ATP Pump

Phospholipids

21. Miguel is looking at cells through a microscope. His
teacher, Ms. Sheng, has told him that he is viewing
either a tomato leaf cell or sheep cell. Ms. Sheng asks
Miguel to figure out what type of cell he is viewing.
What cell structure should Miguel be looking for to
determine whether this cell came from a tomato plant?

Test question number 21

Tomato Cell:

Sheep Cell:

Multiple Choice

Miguel is looking at cells through a microscope. His teacher, Ms. Sheng, has told him that he is viewing either a tomato leaf cell or sheep cell.  Ms. Sheng asks Miguel to figure out what type of cell he is viewing. What cell structure should Miguel be looking for to determine whether this cell came from a tomato plant?

• Chloroplast

• Mitochondria

• Nucleus

• DNA

20. The image below shows the movement of
molecules across a cell membrane. Which
conclusion can be drawn from the image?

Test question number 20

Look at the key and
count the
molecules!!!!

Multiple Choice

The image below shows the movement of molecules across a cell membrane.  Which conclusion can be drawn from the image?

• Water molecules moved from an area of greater concentration to an area of lower concentration.

• 
  Glucose molecules moved from an area of greater concentration to an area of lower concentration.

• Water molecules moved from an area of lower concentration to an area of greater concentration.

• No movement of molecules occurred.

3. Molecules move in and out of a cell by diffusion. The picture
shows a cell and molecules both inside and outside the cell. How will
the molecules in this illustration move as a result of diffusion?

This question asked you to determine how the molecules will move
due to diffusion.

Remember, diffusion is under the category of passive transport.
Passive transport does not require energy because molecules move
across the cell membrane in order to create balance. Ask yourself
how the molecules will move to balance the sides of the cell.

Test question number 3

Multiple Choice

Molecules move in and out of a cell by diffusion. The picture shows a cell and molecules both inside and outside the cell. How will the molecules in this illustration move as a result of diffusion?

• Out of the cell

• Into another cell

• Into the external environment

• Into the cell

Multiple Choice

15. Eukaryotic and Prokaryotic cells have some parts in common. Which of the following pairs or parts would you find in both types of cells?

• cytoplasm and nucleus

• cell membrane and cytoplasm

• DNA and membrane-bound organelles

• cell membrane and membrane-bound organelles

Multiple Choice

4. 4. During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will

• move across the membrane to the outside of the cell.

• stop moving across the membrane.

• continue to move across the membrane in both directions.

• move across the membrane to the inside of the cell.
