Which is a difference between active and passive transport?
Active transport requires ATP, while passive transport does not.
Cells only carry out active transport when they need to move, while passive transport occurs constantly.
Eukaryotes are capable of active transport, while prokaryotes are capable of passive transport.
Cells with mitochondria carry out active transport, while cells without mitochondria carry out passive transport.
Which could be used to represent the plasma membrane’s job?
a gatekeeper allowing cars in and out of a parking lot
a nuclear power plant producing energy
a high school principal running a school
a farmer growing crops
A freshwater plant is placed in a container of saltwater. What will most likely happen to the cells of the plant?
They will shrink because salt will move out of them.
They will shrink because water will move out of them.
They will swell because salt will move into them.
They will swell because water will move into them.
Which will most likely happen if a freshwater plant cell is placed in a beaker of salt water for an hour?
It will lose water and shrink.
It will swell and burst.
It will use energy and pump extra salt out of the cell.
It will reach a state of equilibrium.
What will happen to a cell that is placed in a hypotonic saline solution?
Water will enter the cell causing it to swell.
Water will exit the cell causing it to shrink.
Salt will exit the cell causing it to shrink.
Salt will enter the cell causing it to swell.
