6th-cells Chp 2 test
| Question | Answer |
|---|---|
| diffusion vs. osmosis (how are they similar? | |
| diffusion vs. osmosis (different?) | |
| Why is osmosis so important to the life of a cell? | |
| active vs. passive transport (how are they different? | |
| active vs. passive transport -(examples?) | |
| What do organisms need to survive? | |
| Why do cells need to produce new cells? | |
| Cellular Respiration and Photosynthesis-Know both processes and their equations | |
| Cellular Respiration and Photosynthesis-How are these two processes related? | |
| Where does photosynthesis take place (a specific location in plant cells) | |
| Where does cellular respiration take place (a specific location in animal cells) | |
| What’s fermentation? | the breakdown of carbohydrates by enzymes, bacteria, yeasts, or mold in the absence of oxygen |
| Eukaryotic cells go through what process to make more cells? | |
| Prokaryotic (bacterial) cells go through what process to make more cells? | binary fission (splitting into 2 parts, 2 cells each contain one copy of the circle of DNA) |
| What are the THREE stages of the eukaryotic cell cycle? | |
| Know the PHASES of mitosis (identify what happens in each phase) | |
| Study the diagram on cell cycle from DRA packet 2-3 | |
| What is Celular respiration | the process by which cells produce energy from carbohydrates; atmospheric oxygen combines with glucose to form water and carbon dioxide |
| Photosynthesis | the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce carbohydrates and oxygen |
| endocytosis (write the process and details) | the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell |
| exocytosis (write the process and details) | the process by which a substance is released from the cell through a vesicle that transports the substance to the cell surface and then fuses with the membrane to let the substance out |
| diffusion | the movement of particles from regions of higher density to regions of lower density (less crowded) |
| osmosis | the diffusion of water or another solvent from a more dilute solution (of a solute) to a more concentrated solution (of the solute) through a membrane that is permeable to the solvent |
