HAPPY THURSDAY Bellwork:

Wednesday: Write “Finish Molecule Transport Foldable” and glue to Page 16 of your IAN.Thursday (TODAY): Answer the following questions for the picture.

1. _________ is the movement of water.

2. _______ ________ requires energy to move from low to ______

3. _________ moves sugar/salt in the direction of _______ to _______ .

4. ________ ________ needs a ______ to move through the membrane.

5. The cell membrane is made up of what three molecules?

Test TOMORROW!• What to study:– Prokaryote vs Eukaryote– Cell Theory– Endosymbiotic Theory– Cell membrane (parts & functions)– Hypertonic, Hypotonic, Isotonic– Molecule Transport (Osmosis, Diffusion, Facilitated

Diffusion, Active Transport)

**HOMEWORK VIDEOS are a GREAT tool for review!!

If you search “Alyssa Dolny” on YouTube, the channel pops up first and it’ll be on there as “Test 1 Review”.

Test 1 Review: Youtube

Get out:1. A blank piece of

notebook paper (NOT FROM YOUR I.A.N.!)

2. A pencil

Review DayToday’s Goal: Answer all the review questions correctly (to prepare for

Monday) and figure out the bonus!

• What to do:1. Get a partner2. Start at any question, read it, answer it correctly,

circle the letter it tells you to circle.3. Figure out the bonus after answering all the

questions.4. Turn in your paper when you are done…YES, it is

a grade

1. The cell ______ regulates what enters and leaves the cell.

Membrane

2. What is the diffusion of water across a membrane?

osmOsis

3. A cell membrane is mainly composed of ______, which are

hydrophobic.

Lipids

4. A ______ solution will cause a cell to shrink.

hypErtonic

5. ______ is the amount of a solute (“stuff”) dissolved in a solution.

Concentration

6. Active transport requires energy because the particles are moving

______ (against) the concentration gradient.

Up

7. A eukaryote contains a ______ and other organelles, while a

prokaryote does not.

nucLeus

8. When the concentration of a solution is equal on both sides of a membrane, it has reached ______.

Equilibrium

9. In a ______ solution, water will move into a cell, causing it to swell.

hypoTonic

10. Diffusion, osmosis, and facilitated diffusion are similar because they do not require

______ for particle movement.

eneRgy

11. What is the only type of molecule transport that requires

energy?

Active transport

12. ______ is the movement of particles from an area of high

concentration to an area of low concentration.

diffusioN

13. In this type of solution, water will move equally into and out of a cell, causing no change in the cell’s size.

iSotonic

14. The only example of this cell type is bacteria.

Prokaryote

15. All living things maintain ______ (a stable internal

environment).

hOmeostasis

16. Cell membranes allow some materials to pass through. This makes it selectively (or semi)

______.peRmeable

17. True or false? The three main components (parts) of a cell

membrane are carbohydrates, lipids, and proteins.

True
