Photosynthesis
| Question | Answer |
|---|---|
| What is photosynthesis? | The process by which plants use sunlight, water, and carbon dioxide to produce oxygen and energy in the form of sugar |
| Where does photosynthesis occur in a plant cell? | In the chloroplast |
| What pigment gives plants their green color and captures sunlight? | Chlorophyll |
| What are the raw materials needed for photosynthesis? | water carbon dioxide |
| Where do plants get water from? | Their roots |
| What gas do plants release as a byproduct of photosynthesis? | Oxygen |
| What are stomata? | Tiny pores in leaves that allow gases to enter and exit |
| What is the main product of photosynthesis that plants use for energy? | Glucose (sugar) |
| What is an autotroph? | An organism that can make its own food |
| What is a heterotroph? | An organism that cannot make its own food and must eat other organisms |
| Give an example of an autotroph: | Grass |
| Give two examples of heterotrophs: | Zebra and lion |
| How do heterotrophs get energy from the sun? | Indirectly, by eating autotrophs or other heterotrophs |
| What is the chemical equation for photosynthesis? | Carbon dioxide + Water → Glucose + Oxygen |
| What process do plants use glucose for besides energy? | Cellular respiration, making cellulose and storing for later use |
