Cell Processes
| Question | Answer |
|---|---|
| What is the goal of mitosis? | To make genetically identical daughter cells. |
| What is the goal or meiosis? | To make genetically different daughter cells. |
| Define osmosis. | When water crosses a semi-permeable membrane to reach a state of equilibrium. |
| How is diffusion different than osmosis? | 1. Osmosis is water moving, diffusion can be other things (air freshener, drink mix, etc.) 2. Osmosis needs to have a membrane, diffusion does not |
| How is cellular respiration different from photosynthesis? | Cellular respiration turns the form of energy made during photosynthesis (glucose) into a form of energy the cell can use (ATP) |
| What do chloroplasts do? | They take light energy from the sun and convert it into the chemical energy stored in glucose. |
| In which organelle does photosynthesis take place? | The chloroplast |
| True or false: plants perform both photosynthesis and cellular respiration | True |
| True or false: the products of photosynthesis are the same as the reactants of cellular respiration | True |
| What happens during the process of cellular respiration? | Cells take food in the form of glucose and break it down to release energy in the form of ATP |
| Define dependent variable. | The thing being measured in a scientific investigation |
| What are the reactants of photosynthesis? | Water, carbon dioxide and sunlight |
| What are the products of photosynthesis? | Oxygen and glucose (sugar) |
| What are the reactants of cellular respiration? | Oxygen and glucose (sugar) |
| What are the products of cellular respiration? | Carbon Dioxide and Water |
| In which organelle does cellular respiration take place? | The mitochondria |
| What is located in the chloroplast and helps it perform photosynthesis? | Chlorophyll |
| How do cellular respiration and photosynthesis form a "mini" carbon cycle? | Carbon dioxide the animals breath out after cell respiration is absorbed by plants during photosynthesis |
| Chlorophyll absorbs all light colors except _____, which is reflected. | Green |
| Where do cells get the glucose to complete cell respiration? | Plant cells: from photosynthesis Animal Cells: from food |
| What chemical captures energy from the sun in photosynthesis? | Chlorophyll |
| What gas is absorbed by plants during photosynthesis and given off by animals during cell respiration? | Carbon Dioxide |
| In which phase of mitosis do the chromosomes line up in the middle of the cell? | Metaphase |
| In which phase of mitosis do spindle fibers pull chromosomes away (or apart) from each other? | Anaphase |
| In which phase of mitosis do two nuclei form? | Telophase |
| In which phase of mitosis do chromosomes appear? | Prophase |
