The Cell Processes
| Question | Answer |
|---|---|
| What is the gate keeper of the cell | cell membrane |
| What does selectively permeable mean? | allows some things to enter/exit and blocks passage of others |
| The cell membrane is | selectively permeable |
| What is Homeostasis | steady state or balance |
| What uses Homeostasis, and how | Cell Membrane, responsible for maintaining the steady state within cells |
| What are two examples of Passive Transport | diffusion and osmosis |
| What doesn't get used during Passive Transport | ATP |
| Active transport requires | ATP |
| Cells achieve Homeostasis through | Passive Transport, and Active Transport |
| what is duffusion | when molecules of a solute move from an area of high concentration to an area of low concentration |
| What doesn't diffusion need | ATP |
| What is osmosis | Diffusion of water through a selectively permeable membrane |
| How does water concentrations move in osmosis | high to low |
| In the the cell membrane what passes | Water |
| In the cell membrane, what does not pass | Sugar |
| What is an example of active transport? | Sodium and Potassium |
| What does active transport go against | The Concentration Gradient |
| What is the first of two methods of Active Transport | The cell membrane picks up molecules and carries them using energy |
| What is the second of two methods CALLED of active transport | Engulfing or Phagocytosis |
| How does the second of two methods of active transport work | The cell membrane surrounds the particles and entraps it. This process uses energy |
| What is photosynthesis? | the process that plants use to capture light energy from the sun and use it to make their own food. |
| What do plants need for photosynthesis to occur | Carbon Dioxide and Water |
| How is carbon dioxide let in the plant | through little hole in the leaves called stomata |
| What is the photosynthesis Equation | CO₂ + H₂O → C₆H₁₂O₆ + O₂ Sunlight is on the (→) |
| What is the chemical formula for Water | H₂0 |
| What is the chemical formula for glucose | C₆H₁₂O₆ |
| What is the chemical formula for oxygen | O₂ |
| What is the chemical formula for Carbon Dixoide | CO₂ |
| What are the the elements on the left side of the arrow called | Reactants (Raw Materials) |
| What are the elements on the right side of the arrow called | The Products |
| How many stages does photosynthesis occur in? | 2 |
| What is the first stage of photosynthesis called | Light Dependent Reactions |
| How does the first stage of photosynthesis work | energy from the sun is absorbed by chlorophyll |
| What is the second stage of photosynthesis called | Light Independent Reactions |
| How does the second stage of photosynthesis work | involves the building of sugar |
| What is glucose? | Plants food |
| What is a fancy name for sugar | glucose |
| Where does photosynthesis occur? | in plant cells |
| Why is photosynthesis important to us humans? | We cannot make our own food, so we must get it from plants Plants are the first step in the food chain |
| What are plants called that make their own food | AUTOTROPHS or producers |
| What is the pigment that absorbs the light energy required for photosynthesis | The chlorophyll |
| Where is chlorophyll located? | In the chloroplast |
| What is all of plants food used for | Used by plants to make energy in the mitochondria Can be stored by plants in the vacuoles It can be eaten by a consumer |
| What is a consumer | An Animal |
| What is another name for consumer | Heterotroph |
| What is cellular respiration | When energy is obtained by a breakdown of food molecules |
| Where does the breakdown of food to releasee energy take place | mitochondria |
| What cells have resperation | Plant and animal |
| What is the respiration formula | C₆H₁₂O₆ → CO₂ + ATP (There is no sunlight evolved) |
| In order for cells to undergo respiration they require what | glucose and oxygen |
| What is sugar broken down into | Carbon Dioxide and Water |
| What is ATP used for | cellular activity |
