100
The two categories of cells.
What are prokaryotic and eukaryotic?
100
Two parts: The type of microscope we used in lab (name?) allowed us to see (living OR dead) cells.
What are: light microscope & living cells?

200
The largest level of organization we discussed.
What is the biosphere?
200
The TWO places DNA is located in eukaryotic cells.
The nucleus and ribosomes.
200
The difference of an object/structure compared to those in the same field of view.
What is contrast?
200
This is the difference between an anion and a cation.
anion: a negative ion
cation: positive ion
200
The name & function of organelle #4.
Name: Central vacuole
Function: water storage
300
The THREE levels of organization below an organism.
What are organ system, organs, and tissues?
300
This organelle is the powerhouse of the cell.
What is mitochondria?
300
The ability to see fine detail; a measure of clarity.
What is resolution?
300
The mass number of an atom with 3 protons, 4 neutrons, and 3 electrons.
What is 7? (add 3p+ and 4n = 7)
300
This is the name of organelle #5.
What is endoplasmic reticulum?
400
The definition of biology.
What is the scientific study of life?
400
These FOUR components are the same in prokaryotic and eukaryotic cells.
What are: ribosomes, DNA, cytoplasm, and plasma membrane?
400
This type of microscopy uses specific molecules that can show different cellular components (e.g., structures, protein, organelles).
What is fluorescence microscopy?
400
This is the number of single covalent bonds Oxygen (atomic number: 8) can have.
What is two?
400
This is the name & function of organelle #6.
Name: Golgi apparatus
Function: factory - shipping, receiving, and sorting of vesicles
500
All levels of biological organization from smallest to largest.
What are: atom, molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere?
500
Name TWO tenets of the Cell Theory.
Every living organism consists of one or more cells.
The cell is the basic structural and functional unit of life. Cells are individually alive even as part of a multi-celled organism.
All living cells arise by division of preexisting cells.
Cells contain hereditary material (DNA), which they pass to their offspring during processes of reproduction.
500
This image was taken with a/an ____________ microscope.
What is an electron microscope?
500
This is the definition of a hydrogen bond.
What is: a weak attractive force between a hydrogen atom and either an oxygen or nitrogen atom that are in other molecules or within the same molecule.
500
The type of bond shown between two elements (explain).
What is an ionic bond? This is because an electron is being transferred (stolen) from one element to a more electromagnetic element.
