• It will probably be a Plant Cell
3. Food Web Analysis
• Compare and Contrast two Food Webs
4. Photosynthesis and Cellular Respiration
• Who
• What
• Where
• Why
5. Cell Cycle & Mitosis (Ordering)

Answers to Study Guide (Part 1 - Yellow)

Scientific Method

1. 2 potential problems:
• no experiment was conducted, you cannot prove anything
• two classes may be different (different ages, different genes)
2. meter
3. mile, inch,
4. mile time – dependent variable (this is what you are measuring)
5. typing v. handwriting independent variable (this is what you are changing)
6. chances of getting sick – dependent variable
7.
a. hypothesis – ice cream without chocolate chips will melt slower
b. independent variable – chocolate chips
c. dependent variable – melt time
d. controls – same brand of ice cream, same amount of ice cream
8. Conversions
a. .0735 km
b. 68000 mg
c. 3.648 L

Ecology

1. In order to have a stable food web, it is important to have much more autotrophs than heterotrophs
2. Exponential growth
3. Carrying capacity – maximum amount of organisms that can live in an area without using up all the resources
4. Animals, humans, plant life
5. Weather, precipitation, rain fall, water, soil,
6. More mice would die because there would be more snakes eating, eventually, snake population would go down because there wouldn’t be enough food.
7. Pollution increases the thickness of the atmosphere → traps more of the suns heat → global warming


Cell Parts and Organelles

1. Prokaryotes – no nucleus, no organelles, small
Eukaryotes – has nucleus, has organelles, big
2. Animal Cell (see Notes)
3. Plant Cell (See Notes)
4. Lysosomes
5. Nucleus
6. Ribosomes
7. Mitochondria
8. Chloroplast

Cell Transport

1. Diffusion is the movement of molecules from a high concentration to a low concentration.
2. Salt water fish in hypotonic solution would cause the cell to swell (get bigger)
3. Cell membranes are mostly made up of lipids, with a few large proteins embedded in it to function like a gate
4. Diffusion that happens through a protein is called: facilitated diffusion

Lipids Storage, protection, membranes Fats, oil, wax
Proteins Transport, structure, speed up chemical reactions Skin, hair, muscles, enzymes
Nucleic Acids Store genetic information DNA


Cellular Energy 1 – Photosynthesis

1. Photosynthesis, Light dependent reactions, calvin cycle
2. Carbon dioxide and water to create glucose and oxygen
3. Thylakoid membrane (or grana)
4. Glucose, stroma
5. False. (only plants)
6. Glucose
7. Grana

Cellular Energy 2 – Cellular Respiration

1. Cytoplasm (glycolysis) and Mitochondria (krebs cycle and electron transport chain)
2. Glycolysis, Krebs Cycle, Electron Transport Chain
3. Cytoplasm
4. Mitochondria
5. Oxygen
6. Carbon Dioxide
7. 36
8. plants and animals
9. to get ATP

Cellular Energy 3 – Fermentation

1. oxygen
2. alcoholic and lactic acid
3. yeast
4. humans, bacteria
5. cellular respiration (not fermentation) you get more ATP

Cell Cycle & Specifics of Mitosis and Cancer

1. cell membrane
2. dividing
3. Gap 1 and Gap 2
4. Gap 1 and Gap 2
5. Synthesis (S Phase)
6. Anaphase
7. Metaphase
8. Prophase
9. Abnormal DNA, inability to stop growing
