Cellular Transport Notes

CELLULAR TRANSPORT:
Passive transport: Diffusion, Faciliated diffusion, osmosis
Active transport: Sodium-potassium pump, endocytosis, exocytosis

​Fill in the missing information for passive transport on your handout

Multiple Choice

Diffusion is the movement of:

• water from low to high concentration

• particles from low to high concentration

• water from high to low concentration

• particles from high to low concentration

Multiple Choice

A solute traveling DOWN its concentration gradient using a channel protein does this by ___.

• Facilitated diffusion

• Active transport

• osmosis

• endocytosis

Multiple Choice

This cellular structure helps organisms maintain homeostasis by controlling what substances may enter or leave cells.

• vacuole

• nucleus

• cell membrane

• cell wall

Multiple Select

What are three types of passive transport?

• endocytosis

• diffusion

• osmosis

• sodium-potassium pump

• facilitated diffusion

Multiple Choice

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

• True

• False

​Fill in the missing information for the types of osmosis on your handout.
Including the information for the examples.

Fill in the Blanks

Osmosis is the movement of

across a membrane.

Multiple Choice

This image shows animal blood cells that have been placed in a(n) _____ solution.

• isotonic solution

• hypotonic solution

• hypertonic solution

Multiple Choice

This image shows blood cells that have been placed in a(n) _____ solution.

• isotonic solution

• hypotonic solution

• hypertonic solution

Multiple Choice

Equal percentage of solutes inside and out. 
Concentration of substances is the same. 

• isotonic solution

• hypotonic solution

• hypertonic solution

Multiple Choice

What would happen to an animal cell if you put it in a OVERLY hypotonic solution? Keyword, "overly" remember that nature can take some tolerance but not a lot.

• It will explode and die (lyse)

• It will deflate and die

• It will stay the same

• It will grow larger but stay alive

Multiple Choice

What is active cellular transport?

• The movement of particles from an area of high concentration to an area of low concentration

• The movement of particles from an area of low concentration to an area of high concentration

• The movement of particles without the use of energy

• The movement of particles through vesicles

Multiple Select

Which of the following are required for active transport?

• movement of molecules from high to low concentartion

• energy (ATP)

• carrier or channel protein

Multiple Choice

What is the function of the Sodium/Potassium Pump?

• To move sodium ions out of the cell and potassium ions into the cell

• To move sodium ions into the cell and potassium ions out of the cell

• To move glucose into the cell

• To move water out of the cell
