In this concentration gradient, most blue molecules will move
to the right, becoming more concentrated
to the left, to even out the concentration
to the middle, to make it isotonic
to the bottom, because of gravity.
3 of the answers below require ATP (energy). Which one does NOT need energy to function?
Endocytosis
Exocytosis
Active transport through protein gates
Facilitated diffusion
What is an isotonic solution?
When solutions are in equilibrium (homeostasis)
When the solution has more solute
When the solution has less solute
Has a greater pressure

organelles
blood cells
How can you tell that this is a prokaryote or eukaryote cell?
It is a prokaryote because it doesn't have a nucleus
It is a eukaryotic cell because it has a nucleus
It is eukaryotic because it does not a nucleus nor a cell membrane
It is prokaryote because it has a cell wall
ATP is a form of energy used in which process?
Passive Transport
Active Transport
An animal cell is placed in a hypertonic, super salty solution. Since there is MORE water in the animal cell than in the solution, the cell will -
Stay the same
Shrink- get smaller
Swell- get bigger
burst
Identify the following structure

Why are diffusion and osmosis important to cells?
It allows them to take in materials/substances without using energy.
It allows them to reproduce.
It allows them to absorb sunlight.
It allows cells to use all energy.
When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of ___________.
osmosis
equilibrium (homeostasis)
diffusion
hypertonic
What does selectively-permeable mean?
Allow certain things to enter and leave the cell
Nothing gets through
The cell lets only large substances through

Osmosis
Diffusion
Active Transport
To pump a solute across a membrane AGAINST its gradient requires work; the cell must expend energy. Which of the processes below require energy?
active transport
passive transport

gated channels
The cell membrane maintains...
Energy
Homeostasis/Equilibrium
The cell looking good
What is the definition of Selective Permeability?
The movement of materials across the cell membrane that requires NO ENERGY from the cell.
The movement of materials through (or across) the cell membrane
The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
If you looked at red blood cells under a microscope and saw the blood cells exploded, what would you say happened?
The cells were placed in a hypotonic solution.
the solution was isotonic.
The solution was hypertonic.
When the concentration of particles inside of a cell is the same as the concentration of particles outside of the cell.

When a cell forms a vesicle around unwanted particles and expels it OUT of the cell.
Pinocytosis
Endocytosis
Receptor-mediated
Exocytosis
Which way will the small molecules if no energy is used?
Out of the cell
Into the cell
They won't move at all
Which of the following provide evidence for the endosymbiotic theory?
Large prokaryotic cells engulfed smaller prokaryotic cells, they coexisted within the host cells with double-membrane bound organelles: nucleus, mitochondria, and chloroplast.
Large prokaryotic cells engulfed smaller prokaryotic cells, they did not coexist within the host cell and resulted in being digested.
Small prokaryotic cells engulfed large prokaryotic cells, they did not coexist within the host cells and resulted in being digested.
