Biology M3 Review Part 3 (W7)

isotonic

A/an _____ solution allows cells to be balanced with the same amount of water moving in and out of the cell.

Active transport and passive transport are different in two ways. While passive transport moves molecules from high to low concentration, active transport moves molecules from low to high concentration. Plus, active transport requires energy but passive energy does not.

Compare and contrast the two types of cell transport. Respond in 2-3 complete sentences using your best grammar.

solvent

Water is called the "universal _____" because of its ability to dissolve most substances.

Hydrophilic

Water-loving

Hydrophobic

Water-resistant

Homeostasis is the need for our cells and bodies to maintain balance. Our bodies make us shiver when we are cold and make us sweat when we are hot to maintain homeostasis.

What is homeostasis and how do our bodies work to maintain it? Respond in 2-3 complete sentences using your best grammar.

-Panting -Drinking water -Shivering -Sweating

Which of the following are methods of maintaining homeostasis? (Select all that apply.)

-Exocytosis -Endocytosis -Membrane Pumps

Which of the following are types of active transport? (Select all that apply.)

-Osmosis -Simple diffusion -Facilitated diffusion

Which of the following are types of passive transport? (Select all that apply.)

Hypertonic

A solution that contains a higher concentration of solutes than the inside of the cell, & water moves out

Hypotonic

A solution that contains a lower concentration of solutes than the inside of the cell, & water moves in

Passive transport

Molecules move from a high to low concentration without using energy

Active transport

Molecules move from a low to high concentration using energy

Homeostasis

Stable internal conditions

Isotonic

The amounts of solute on the inside and outside of the cell are equal, & water moves in and out

ATP

The energy used to fuel active transport is called adenosine triphosphate, also known as _____.
