100
This organelle controls what enters or leaves the cell
cell membrane
100
These structures may be found floating freely in the cytoplasm or attached to the endoplasmic reticulum; site of protein synthesis.
Ribosomes
100
Does not require ATP
What is passive transport
100
Define Diffusion
Movement of PARTICLES from high concentration to low concentration
100
List four basic structures that are common to all types of cells.
All cells are surrounded by a barrier (cell membrane).
All cells have an interior substance (cytoplasm).
All cells have DNA
All cells have ribosomes
100
Give ONE reason why some of the particles were able to diffuse across the dialysis tubing membrane.
Particles moved from high to low concentration.
Particles were small enough to diffuse.
200
the portion of the cell within the membrane that includes a "jelly" like fluid and all organelles except for the nucleus.
cytoplasm
200
This organelle converts glucose and other organic molecules into a form of usable cell energy called ATP.
Mitochondria
200
The sodium-potassium pump is an example of this; keeps sodium from building up in the cell by moving sodium against the concentration gradient.
Active transport
200
Diffusion of water is called?
Osmosis
200
does not have a true nucleus or any membrane-bound organelles.
What is a prokaryotic cell?
200
High solute and low water concentration. Causes cells to lose water and shrink.
Hypertonic environment
300
This organelle sorts and packages proteins and ships them to their final destinations.
Golgi apparatus
300
These name for condensed DNA and serve as the storehouse for genetic information.
Chromosomes
300
Filtration, simple diffusion, dialysis, osmosis are examples of what?
What is passive transport
300
When the cell needs to use energy to move things across the membrane
Active transport
300
has a true nucleus and membrane-bound organelles.
what is a eukaryotic cell?
300
Food coloring diffusing in water is which type of transport?
Passive Transport
400
controls all the activities of the cell, including cell reproduction and protein synthesis
Nucleus
400
Modifies and transports proteins after they are built.
Rough ER
400
If you have a high amounts of water in solution A, and low amounts water in solution B. What would you expect to happen?
What is solution A moving with the concentration gradient towards solution B.
400
Movement across the membrane that does not need energy, but does need help from transport proteins
Facilitated diffusion
400
What organisms are prokaryotes?
What organisms are eukaryotes?
Bacteria are prokaryotes. Animals, Plants, Fungi, and Protists are eukaryotes.
400
Cellular respiration involves animals and plants taking in glucose (chemical energy) and oxygen. The products are?
carbon dioxide, water, and ATP energy
500
What is the difference between the rough ER and the smooth ER?
Rough ER has ribosomes attached to it. Smooth ER has no ribosomes.
500
In what place are the ribosomal subunits manufactured?
Nucleolus
500
Vesicles transport wastes out of the cell through this process; type of active transport
Exocytosis
500
Which way will the pink molecules diffuse?
To the right
500
This material is found in the cell walls of fungus and the exoskeletons of arthropods.
Chitin
500
The ingestion of liquid into a cell by the budding of small vesicles from the cell membrane
What is pinocytosis
600
These small spherical sacs that are classified by their contents may contain enzymes or other types of proteins for transport.
Vesicles
600
This organelle makes the lipids that will be used in membranes.
Smooth ER
600
Molecules that are too large to move in the cell are transported through this process.
endocytosis
600
If you have high amounts of glucose in solution A and low amounts of glucose in solution B, what would happen to the water.
What is the water moving towards solution A.
600
Cell respiration involves animals and plants taking in glucose (chemical energy) and oxygen. The products are?
carbon dioxide, water, and ATP energy
600

Active Transport
700
When will a substance be likely to enter a cell through diffusion?
When the concentration of the substance is greater outside the cell than in.
700
