Germs or what type of cell? |
• bacteria • Single celled |
|
|
Bacteria accounts for how much of your bodyweight a percentage? How much of you is bacteria in pounds |
1.)10% 2.)19.21lbs |
|
|
How are prokaryotes and eukaryote different? How are they the same? |
•Eukaryote has nucleus, hold DNA • prokaryotes no nucleus, DNA is loose |
|
|
How does a bacteria become antibiotics resistant? |
Starts with a nutation, bacteria that survive go on to multiply it passed on resistant gene to other |
|
|
How do you bacteria cells divide? |
Binary fission |
|
|
Is bacteria good or bad for humans? |
Some are good and some are bad |
|
|

|
Cell membrane |
Protect cell from surroundings |
|
|
Nucleus |
Stores DNA |
|
|
Golgi body |

|
|
What are the differences between plant and animal cell |
• plant cell have a cell wall • animal cells only have cell membranes |
|
|
What is ATP and why is it important to thecell |
1.)Adenosine Triphosphate 2.) cells need energy to carry out task |
|
|
What are five facts about ATP |
•Every cell uses ATP • One molecule of ATP contains three phosphate groups • ATP could be used for many things • ATP is the main energy source |
|
|
What does an Enzyme do for the cell |
Speed up chemical reactions and help digest sugars in the foods we eat |
|
|
What is the model use to demonstrate enzymes |
Lock and key model |
|
|
What could denature enzymes |
Extreme temperatures, and wrong pH |
|
|
What can happen if a person lacks an enzymes? Give an example |
1.) can not digest that certain substrate lactose intolerance Ex: Can’t digest the lactose sugar |
|
|
The cell membrane is said to be semipermeable, what does that mean |
Certain things can go in but not others |
|
|
What is homeostasis and why is it important |
1.)Homeostasis is constant state of normal 2.) keeps the cell at optimal living conditions |
|
|
How is homeostasis different in single cell organisms from multicellular organisms |
1.) Single cell has to maintain homeostasis on its own 2.) multicellular specialized cell who’s job is specifically to maintain homeostasis |
|
|
What is the difference between active and passive transportation |
Active= Energy needed, large molecules Passive=No energy, small molecules |
|
|
What is osmosis |
Net movement of molecules through semipermeable membrane |
|
|
What is the difference between hypertonic,hypotonic, and isotonic |
•Hypertonic is high solute which shrinks cell • Hypotonic is low solute which swells cell •Isotonic is the same solute and nothing happens because it stays the same |
|
|
A hypertonic solution causes a cell to do what |
Shrink |
|
|
A hypotonic solution causes a cell to do what |
Swells |
|
|
What happens during endocytosis |
Particle comes into cell |
|
|
What happens during exocytosis |
Particles released from cell |
