The cell is in a _____________ solution.
Therefore the cell is going to _____________ (shrink, swell, or stay the same)
Name that Tonic.
The cell is in a _____________ solution.

•Active Transport
10
Cell must use energy to move molecules across membrane
-Usually against a concentration gradient
-Pay cash to get into a crowded club
Ex. Getting into the clubOR Swimming against the current
-Moves from Low to High concentration
Active Transport
Active Transport
-Uses energy
-Moves bigger particles with carrier proteins
ATP
•PASSIVE TRANSPORT
13
Cell does not need to use energy to move molecules across membrane -Usually with a concentration gradient
-Free to exit a crowded club
Ex. Getting out of the clubOR Floating with the current
Activity 1. Passive vs. Active Grid
Activity 2: Passive and Active Venn Diagram
Activity 3: Passive and Active Situations (Schoology)
Active Transport
Passive Transport
Fill in the Venn Diagram Below. Some things to consider as you fill it in….. -size of molecules -energy -carrier/transport proteins used -concentration gradient – Direction particles move -Types - What is the purpose of Transport You should also include at least 3 of your own ideas of how they are alike and different that are not from the list above.
