mrs.petermans 1st 9 weeks biology exam
| Question | Answer |
|---|---|
| students decided 2 ignore any results that were 2 far above or below their prediction 4 their hypothesis. Instead, they repeated their experiment over and over until a value closer to their prediction was obtrained. How does the decision to ignore the dat | It introduces bias. |
| what do enzymes do during a chemial reaction? (also has a graph on the test w/ this question) | lowers the required activation energy |

| How do enzymes help in the process of digestion? | they assure that digestion occurs within hours instead of days. |
| what do enzymes do during a chemial reaction? (also has a graph on the test w/ this question) | lowers the required activation energy |
| what are enzymes? | Proteins |
| How do enzymes help in the process of digestion? | they assure that digestion occurs within hours instead of days. |
| what are enzymes? | Proteins |
| enzymes are necessary for chemical reactions b/c... | *they are catalysts-they speed up reactions *withouth enzymes the reactions would be too slow to meet the needs of the cell. |

| what type of cell is square and has a nucleus? (w/ a picture on the test) | plant cell |
| how can you tell a plant cell from an animal cell? *plant cells have a cell membrane *plant cells have a nucleus *plant cells have cytoplasm *plant cells have a cell wall | plant cells have a cell wall |
| this square cell w/ a nucleus is found in what organism? *bacterium? *moss? *paramecium? *yeast? | moss |
| plant cells have what? | cell walls large vacuoles and chloroplasts |
| animal cells have what? | centrioles and cilia/flagella |
| how can you tell a plant cell from an animal cell? *plant cells have a cell membrane *plant cells have a nucleus *plant cells have cytoplasm *plant cells have a cell wall | plant cells have a cell wall |
| during photosynthesis: what happens to carbon dioxide? | its taken in by the plants |
| prokaryotic cells have what? | *bacteria *primitve cells *no nucleus or membrane bound organelles |
| during photosynthesis: what happes to the oxygen/water vapor | it is given off by the plants |
| eukaryotic cells have what? | *they are modern cells *they are all cells but bacteria *membrane bound nucleus and organelles. |
| in the diagram showing the relationships b/t photosynthesis and cellular respiration. what do the #ered boxes represent? | 1=oxygen/2=carbon dioxide |
| which of the following is a characteristic of both prokaryotic and eukaryotic cells? *both cells undergo mitosis *neither cell has a nucleus *both cells contain DNA(genetic material) *neither cells have a mitochondrion | both cells contain DNA(genetic material) |
| pores in a plants leaves that open/close to allow the intake of oxygen/the release of carbon dioxide and water vapor (during photosynthesis) | Stoma |
| during photosynthesis: what happens to carbon dioxide? | its taken in by the plants |
| during photosynthesis: what happes to the oxygen/water vapor | it is given off by the plants |
| in the diagram showing the relationships b/t photosynthesis and cellular respiration. what do the #ered boxes represent? | 1=oxygen/2=carbon dioxide |
| transports water from roots to rest of plant... | xylem |
| in what ways are photosynthesis and cellular respiration alike? *both processes require chlorophyll *both processes require glucose *both processes consume carbon dioxide *both processes involve energy transformations | both processes involve energy transformations |
| transports glucose from leaves to rest of plant... | phloem |
| all organic molecules contan CARBON atoms. which of the following involves the recycling of carbon in the environment? *evaporation and condensation *transcription and translation *diffusion and translation *photosynthesis and respiration | photosynthesis and respiration |
| most plants are what...? | vascular |
| plants that have vascular tissues that transport substances through-out the plant... | vascular plants |
| (tubes) | vascular tissues |
| a graph tgat shows a cross section in a plant organism...what is the cross section of? | a leaf |
| transports water from roots to rest of plant... | xylem |
| transports glucose from leaves to rest of plant... | phloem |
| most plants are what...? | vascular |
| these plants do not have vascular tissues to carry food and nutrients...instead they rely on osmosis/diffusion to transport food/water/nutrients through-out the plant | nonvascular plants |
| a graph tgat shows a cross section in a plant organism...what is the cross section of? | a leaf |
