photosynthesis
| Question | Answer |
|---|---|
| autotroph | (“self”) an organism that makes its own food, a producer. They include plants, other organisms such as algae & few bacteria |
| Heterotroph | (“other”) an organism that CANNOT make its own food, a consumer |
| A producer can also be called ______ | autotroph |
| A consumer can also be called ______ | heterotroph |
| T/F some organisms absorb their food from other organisms | TRUE; some heterotrophs such as fungi |
| nucleus | the organelles that acts as the cell’s control center and directs cell’s activities |
| chloroplasts | organelles that capture energy from sunlight and use it to produce food for the cell |
| mitochondria | organelles that convert energy in food to energy that cells can use to carry out their functions |
| What is plant food? | fertilizer that contains minerals such as potassium, Calcium, phosphorus. It helps plants grow, but does not supply them with energy! |
| What would happen if you put a small seedling in darkness? | it grows very little since it cannot make its own energy |
| Photosynthesis | the process by which a cell captures energy in sunlight and uses it to make food |
| T/F most living things obtain energy from the sunlight captured during photosynthesis | TRUE. Some obtain energy directly (grass) while others obtain energy indirectly (zebra, lion) |
| Explain photosynthesis | process whereby plants/other organisms absorb sun’s energy & use it to convert carbon dioxide and water into sugars and oxygen |
| First stage of photosynthesis | Energy from sunlight captured + water in chloroplasts is split into hydrogen and oxygen (waste) |
| Second stage of photosynthesis | cells produce sugar using hydrogen obtain from stage one photosynthesis + CO2 from air |
| Sugars are a | type of carbohydrate |
| Where does photosynthesis occur? | mostly in the leaves; within the green organelle called chloroplasts |
| What is the main pigment for photosynthesis | chlorophyll |
| Explain relationship between chlorophyll and chloroplasts? | chlorophyll is found in chloroplasts |
| State the photosynthesis equation | light energy + 6 CO2 + 6 H2O ——> C6H12O6 + 6 O2 |
| What are the raw materials of photosynthesis? | Carbon dioxide and water |
