Hypotheses and Theories
100
Never found in bacterial cells, these membrane-bound structures make ATP in eukaryotic cells.
What is mitochondria?
100
Not considered a living organism, these infectious agents need a host to grow, reproduce, or perform metabolic reactions.
What is a virus?
100
Consisting of an amino group, carboxylic acid group and R-side chain, this monomer builds proteins.
What is an amino acid?
100
Movement of a substance across the cell membrane from low to high concentration.
What is active transport?
100
Viruses are not included in this theory because they are not made of cells and cannot reproduce on their own.
What is the cell theory?
200
Large cells that contain organelles.
What are eukaryotic cells?
200
The skin and circulatory system work with this system to defend the body against pathogens.
What is the immune system?
200
A sugar, a phosphate group, and a nitrogen base form a nucleotide which is the building block (monomer) of which organic compound?
What is a nucleic acid?
200
This happens to a cell when it is in a watery, hypotonic environment.
What is swelling/bursting?
200
According to this theory, mitochondria and chloroplasts were once cells that lived independently.
What is the endosymbiotic theory?
300
Not to be confused with the cell membrane, this protective structure may be found on the outside of both eukaryotic cells and prokaryotic cells.
What is the cell wall?
300
This body system works with the digestive system to deliver nutrients to cells.
What is the circulatory system?
300
Best described as a straight chain, this biomolecule is made of mostly carbon and hydrogen.
What is a lipid?
300
In humans, glucose is kept in balance in the bloodstream by insulin. Which concept does this best illustrate?
What is Homeostasis?
300
This theory states that all cells come from preexisting cells.
What is the cell theory?
400
Structures, such as the lysosome, vacuole, and Golgi body, that work together to carry out cell functions
What are organelles?
400
Immediately after eating, this substance increases in the blood.
What is glucose?
400
The main energy source of living things.
What is a carbohydrate?
400
The level of organization in a biological system that is more complex than an organ.
What is an organ system?
400
These two organelles have their own DNA, similar to that of prokaryotes providing evidence for the endosymbiotic theory.
What are mitochondria and chloroplasts?
500
Made of lipids, this cell structure provides a barrier to the movement of substances in and out of the cell.
What is the cell membrane?
500
Made of peptidoglycan, this structure makes bacteria especially hard to kill.
What is the cell wall?
500
The two biomolecules that contain nitrogen.
What are proteins and nucleic acids?
500
A decrease in urine output indicates a problem with this body system.
What is the excretory system?
500
The Urey-Miller experiment demonstrated that these could be formed from inorganic substances.
