Cells --> Tissue --> Organ --> Organ System --> Organism
Levels of Biological Organization; Hierarchy of subsystems
100
The smallest unit of capable of sustaining life
What is a cell?
100
A single-celled organism
What is a unicellular organism?
100
The process of enclosing organelles within membranes to increase the efficiency and safety of an eukaryotic cell.
What is compartmentalization?
100
One property of stem cells
What is:
-divide and make more undifferentiated stem cells?
-respond to signals to make differentiated cells?
200
Genus species
What is the correct format of naming a species? What is the format for binomial nomenclature?
200
The 3 statements of the cell theory
All living things consist of cells
Cells are the basis for life
All cells arise from pre-existing cells
200
Nucleoid
Where is the region where DNA is found in prokaryotes?
200
I have a chitinous cell wall, no centrioles, and I absorb nutrients for energy.
What is a fungus?
200
The cause of cell differentiation
What is
-chemical signals influencing gene expression?
-genes turned on or off that influence cell shape and function?
300
Name 3 processes of life
What is:
nutrition, metabolism, homeostasis, reproduction, growth & development, response to stimuli, excretion, (movement is no longer a process of life!)?
300
The reasoning that led to the cell theory
What is inductive reasoning?
300
DNA, cytoplasm, Cell membrane
What are the structures found in all cells?
300
Where ribosomes are made
What is the nucleolus?
300
Benefits of cell differentiation
What is:
-more specialized functions in organism/cell?
-a more efficient cell/better adapted cell?
-cells of different shapes and sizes?
400
True or False: Intraspecies variation is the differences between different species
What is false? Intraspecies variation are differences within the same species (ex: differences between E. coli and E. coli)
Interspecies variation are differences between different species (E. coli vs H. sapiens)
Interspecies variation are differences between different species (E. coli vs H. sapiens)
400
Immunofluorescence
What is a development in microscopy that allows you to tag and track proteins and other molecules moving throughout the cell?
400
Size of prokaryotic ribosomes
What is 70S?
400
True or False: All eukaryotes have a nucleus.
What is "technically false"? Typically, all eukaryotes have one nucleus in each cell. However, there are atypical eukaryotic structures that lack a nucleus or a multinucleated
400
True or False: Multipotent stem cells can create any type of body cell of the organism
What is false? Totipotent stem cells can create any type of body cells of the organism. Multipotent stem cells can differentiate into a limited range of cell types (that are of similar cell types)
500
The type of species variation with more differences than similarities.
What is interspecies variation?
500
I / A * M
What is the formula to calculate the different sizes (image/drawing, actual, magnification) of ultrastructures viewed under a microscope?
500
True or False: All unicellular organisms are prokaryotes
What is false? There are unicellular eukaryotes (like Amoebas, Euglena, Paramecium)
500
Draw the structure that packages and sorts proteins
Students correctly drew the golgi apparatus.
500
Example of a pluripotent stem cell
What is a blastocyst? What is an early embryonic cell?
