Activity 1: Cornell Notes

Main Ideas / Questions: 1. 2. 3.

Notes:

• The cell membrane controls _______________________________ ______________________________________________________

• The cell membrane is made mostly of _______________________,

but also has ____________________ that help move molecules in and out of the cell

Big Idea Molecules like to go from _________________ concentration to ____ concentration. (they like to be __________________________)

Stop-and-Jot: In which side of the beaker below is there a higher concentration of salt – Left or Right? Where will the salt tend to move?

• There are 2 ways molecules are transported in and out of the cell:

1) ________________ transport = the transport of substances into or

out of the cell from an area of ________ concentration to an area of _______ concentration ______________ using cell energy

a. Example: _____________________ b. Example: _____________________ c. Example: _____________________

Main Ideas / Questions: 4. 5.

Notes:

2. ________________________ transport = the transport of substances into or out of the cell from an area of __________ concentration to an area of ________ concentration _____________ the use of cell energy

Stop-and-Jot: What are the key differences between passive and active transport? What are some useful analogies to use to remember these differences?  

 

 

 

 

• ___________________ = movement of small solute particles from an area of high concentration to an area of low concentration without the use of cell energy

Type of Transport: ______________________________

Key Points:

§ What is moving? __________________ § Where is it moving? ________________ § Does it need energy? _______________ § Does it need proteins? ______________

Main Ideas / Questions: 6. 7.

Notes:

• ___________________ = movement of water molecules from an area of high concentration to an area of low concentration without the use of cell energy

Type of Transport: __________________________

Key Points: § What is moving? __________________ § Where is it moving? ________________ § Does it need energy? _______________ § Does it need proteins? ______________

Stop and Jot: What is the difference between diffusion and osmosis?

• ___________________ = movement of large molecules from an area of high concentration to an area of low concentration without the use of cell energy, but with the assistance of channel proteins

Type of Transport: ___________________________ Key Points:

§ What is moving? __________________ § Where is it moving? ________________ § Does it need energy? _______________ § Does it need proteins? ______________

Activity 2: Time to Practice! 1. Fill: Place a CHECK in the box that fits with each of the following types of transport

Transports

substances into the cell

Uses proteins

Uses energy

Transports substances from a HIGHER to LOWER concentration

Transports substances from a LOWER to HIGHER concentration

Transports water

Diffusion

Osmosis

Facilitated Diffusion

Active Transport

Main Ideas / Questions: 8.

Notes: Stop and Jot: What is the difference between diffusion and facilitated diffusion?

• ___________________ = movement of large molecules from an area of low concentration to an area of high concentration with the use of cell energy (ATP) and protein pumps

Type of Transport: ________________________ Key Points:

§ What is moving? __________________ § Where is it moving? ________________ § Does it need energy? _______________ § Does it need proteins? ______________

Stop and Jot: What is the difference between facilitated diffusion and active transport?
