Cell Stuff
Two prokaryotic domains of life?
Bacteria, Archaea
What is genetic material? What is it made of?
A molecular blueprint that allows organisms to grow, develop and evolve. DNA, RNA.
What is homeostasis? What factors do we regulate in homeostasis?
Relatively stable internal environment, PH, temperature
Mitosis produces genetically _______ daughter cells
IDENTICAL
What is simple diffusion?
Movement of ions and molecules from an area of HIGH concentration of solute, to an area of low concentration of solute.
Full points only if you added the words solute or explained WHAT is high/low conc. 1/2 points otherwise
One function of the plasma memberane?
Selective barrier, allows certain substances in and doesn't let in others.
Genetic diversity is brought about by..
Genetic mutations, sexual reproduction.
How do cells extract energy from food?
Chemical reactions!
Meiosis produces genetically _________ daughter cells. These cells are genetically _______ from the parents and eachother.
DIFFERENT, DIFFERENT
True or false, simple diffusion uses the help of Energy or a membrane protein
FALSE.
Why are membrane-bound organelles important in Eukaryotic cells?
Allows for separation of function and concentration of materials
The two nucleic acids' full names and their purpose.
Deoxyribonucleic acid. Ribonucleic acid. Store genetic information.
The 3 products for Cellular Respiration
6H2O, 6CO2, ATP
What forms reproductive cells? What are these reproductive cells scientifically called? What are their names in day to day life?
Meiosis. Gametes. Sperm and egg.
Draw out or define osmosis.
Diffusion of water from an area of high concentration of water to low concentration of water.
3 structures in the prokaryotic cell. BONUS DOUBLE POINTS if you can pinpoint each function.
Nucleoid, DNA found here. Plasma membrane, controls substance passage. Cell wall, rigid for protection. Glycocalyx, for preventing dessication. Flagella, movement. Ribosomes, produce proteins. Cytoplasm, everything else inside where chemical rxns take place. Pili - thin projections for movement
What is the FULL central dogma?
DNA --- transcription----MRNA---- translation----Protein
The 3 products for Photosynthesis
C6H12O2, 6O2
The role of mitosis?
growth, cell replacement, wound repair
What are the three permeable environments we learned when talking about osmosis? Draw or define
Iotonic, hypertonic, hypotonic
5 components in a eukaryotic cell that are NOT in the prokaryotic cell
Peroxisomes, mitochondria, nucleus, golgi, SER, RER, cytoskeleton.
What are the names of the 4 nucleotides?
Adenine, Guanine, Thymine, Cytosine
The FULL equation for BOTH photosynthesis and cellular respiration. How are these two connected within the environment?
6H2O + 6CO2 -> C6H12O6+ 602.
C6H12O2 + 602 -> 6H2O + 6CO2 + ATP.
One's products are the other's reactants and vice versa.
Draw out the life cycle in humans from female and male to the final product.

A red blood cell is placed in a solution with a lower concentration of solutes than inside the cell.
This is a hypotonic solution.
Water will move into the red blood cell from the surrounding solution.
The red blood cell will swell and may eventually burst (a process called hemolysis).
