What is osmosis?
The movement of water molecules from an area of higher concentration to a lower concentration.

Where does photosynthesis take place inside the cell?
Chloroplast
100
True or false: Animals can make their own food?
False

What did the vinegar do in the Eggsperiment?
Dissolved the shell
100
What is fermentation?
Breakdown of sugar into energy that doesn't require oxygen
200
What is diffusion?
The movement of materials from an area of high concentration to an area of low concentration.
200
What does the sunlight do in photosynthesis?
Breaks apart the bonds
200
Where does respiration take place in a cell?
mitochondria and cytoplasm
200
What organism did we use for the respiration lab?
Yeast
200
Mitosis creates cells with how many sets of DNA?
1 full set - the cell is identical to the parent cell.
300
What is active transport?
Movement of materials across a cell membrane that requires energy
300
What do the terms: photo and synthesis mean?
photo = light synthesis = to make, or put together
300
What is ATP?
energy produced in respiration
300
What pieces of equipment did we use for the respiration lab?
Lab Quest and CO2 sensor
300
What is one use of the fermentation process?
Beer or wine Bread antibiotics
400
What is a selectively permeable membrane?
Allows certain material to pass through, but not all
400
What is the photosynthesis reaction in words?
carbon dioxide + water + sunlight MAKES sugar and oxygen
400
What is the reaction of respiration in words?
sugar + oxygen MAKES water + carbon dioxide + energy
400
Why did the egg get bigger when we put it in water after putting it in corn syrup?
Osmosis - the water moved into the egg, where the water was less concentrated. It was more concentrated outside, so the water moved into the egg.
400
Fermentation results in what product besides carbon dioxide in yeast? In people?
Yeast - alcohol People - lactic acid
500
What is exocytosis?
The process of moving large particles out of the cell.
500
What is the chemical formula for photosynthesis?
6 CO2 + 6 H2O + sunlight = C6H12O6 + 6 O2
500
What is the chemical formula for respiration?
C6H12O6 + 6O2 = 6 CO2 + 6 H2O + energy
500
What three factors had an impact on the rate of photosynthesis?
Level of CO2 Level of light Color of light
