Does not require ATP
passive transport
100
Define Diffusion
Movement of molecules from high concentration to low concentration
100
List three basic structures that are common to ALL types of cells.
All cells are surrounded by a cell membrane.
All cells have cytoplasm.
All cells have DNA.
100
Paramecium use what structures to move around and sweep food toward their "mouth"?
cilia
200
Gel-like fluid that fills the space inside the cell and surrounds the organelles.
cytoplasm
200
Molecules moving from low concentration to high concentration across the cell membrane.
active transport
200
Diffusion of water is called?
Osmosis
200
Does not have a true nucleus or any membrane-bound organelles.
prokaryotic cell
200
Euglena use what structures to move around?
flagellum
300
Controls all the activities of the cell, including cell reproduction and protein synthesis.
Nucleus
300
Diffusion and osmosis are examples of which type of transport?
passive transport
300
Low solute and high water concentration outside the cell could cause cells to swell and burst.
Hypertonic solution
300
Has a true nucleus and membrane-bound organelles.
eukaryotic cell
300
Amoeba use what structures to move around and catch prey to eat?
pseudopods
400
What is the difference between the rough ER and the smooth ER?
Rough ER has ribosomes attached to it. Smooth ER has no ribosomes.
400
When the cell needs to use energy to move things across the membrane.
Active transport
400
High solute and low water concentration outside the cell could cause cells to lose water and shrink.
Hypertonic solution

What do Euglena use their eyespots for?
to find light
500
This organelle sorts and packages proteins and ships them to their final destinations.
Golgi apparatus
500
Movement across the membrane that does not need energy, but does need help from transport proteins.
Facilitated diffusion
500
Which way will the water molecules (small pink dots) diffuse? (right or left)
To the right
500
What organisms are eukaryotes?
animals, plants, fungi, and protists
500
Calculate the magnification for the highest-powered objective lens on the compound light microscopes we used in our lab.
10 x 40 = 400 X
600
This organelle converts glucose and other organic molecules into a form of usable cell energy called ATP.
Mitochondria
600
A type of active transport that keeps sodium from building up in the cell.
sodium-potassium pump
600
A solution with an equal solute concentration to the inside of the cell.
Isotonic solution
600
Which are the smallest types of cells?
prokaryotic cells

Which 2 structures do protists use to maintain the right balance of water and solutes inside their cell?
cell membrane and contractile vacuole
700
Name this organelle:
Chloroplast
700
When does diffusion of molecules stop?
when equilibrium is reached
700
If you have high amounts of glucose in the solution surrounding a cell and low amounts of glucose inside the cell, what would happen to the water molecules inside the cell?
The water molecules will move toward the outside of the cell.
700
In which type of cells does DNA coil up into chromosomes?
eukaryotic cells
700
What may happen to an amoeba if we placed it in saltwater?
it may shrink and shrivel up
