Why is a rock not considered a living thing. Be sure to answer in reference to Cell Theory
It is not made of cells, and is not produced by a living thing.
100
This type of particle motion needs energy to happen.
What is active transport.
100
What are the two stages of photosynthesis?
Light independent and light dependent (Calvin Cycle)
100
What are the three stages of cellular respiration?
Glycolysis, Krebs cycle, and electron transport chain.

G1, S, G2 and Mitosis are the four stages of the cell cycle. Tell me what happens in each stage.
G1 - normal functions s - DNA replicated G2 - extra growth Mitosis - nucleus divides

If you found an object and placed it under a microscope, what would you need to see to confirm it was a living thing?
Cells.
200
Draw a picture of a cell in a hypertonic solution. Be sure to draw arrows indicating which direction water would move.
Answer on board.
200
What are the starting and ending pieces for the first step of photosynthesis?
sunlight + water --> ATP + oxygen
200
What are the starting and ending pieces of the second stage of cellular respiration?
pyruvate --> ATP, NADH and FADH2 + CO2
200
Draw me a picture of the four stages of Mitosis, make sure to label each stage. Then draw a picture of cytokinesis.
See board.
300
Trace the path of protein production from the nucleus to exiting the cell.
Nucleus --> ER --> Golgi --> vesicle --> fusion with cell membrane
300
Passive transport moves particles in what direction in reference to the concentration gradient?
What is down or from high to low.
300
What are the starting and ending pieces of the second stage of photosynthesis?
ATP + CO2 --> sugar
300
What are the starting and ending pieces of the third step of cellular respiration?
NADH + FADH2 + oxygen --> ATP + water
300
How does asexual reproduction reduce genetic variation?
Because you are making clones rather than combining more than one set of DNA to make offspring.
400
This is where cellular respiration takes place. What does this organelle produce?
Mitochondria. Energy.
400
Draw a picture of exocytosis.
See board.
400
Where does photosynthesis take place? Be precise about the location of each step.
On the thylakoid membrane and then in the stroma.
400
What happens when oxygen is not in high enough concentration for cellular respiration to happen?
Fermentation
400
Looking through a microscope you are unsure if you are looking at a prokaryote or a eukaryote in the middle of mitosis. Why might this be misleading?
The nuclear envelope breaks down during mitosis which is one of the easiest distinguishing factors between prokaryotes and eukaryotes.
500
What would happen if we did not have a nucleus?
Things could more easily attack our DNA.
500
If a cell was suspended in an isotonic solution, what would happen to the cell if salt was added to the cell?
The cell would burst. Water would rush into the cell.
500
Why can plants survive in a sealed container with only water added to it before sealing?
Because as long as they can still get sunlight, the plant will recycle. Take in CO2 during photosynthesis and produce sugar and oxygen. That sugar and oxygen can be used in cellular respiration to release energy and CO2. Which is then recycled again.
500
Do you think cellular respiration would be exothermic or endothermic? How do you know?
Exothermic because it releases energy as heat and ATP
500
What do you think would happen to a cell if it did not double its DNA before going through mitosis?
It would only have half the number of chromosomes it was supposed to have. It would actually be going through meiosis to make an egg or a sperm.
