| Question | Answer |
|---|---|
| When we observed a fresh plant leaf under water, what gas caused bubbles to form on the leaf? | Oxygen |
| This organelle in plant cells allows them to use the sugar they make to produce ATP | Mitochondria |
| How would light intensity affect the number of bubbles on the leaf? | Higher light intensity would increase the number of bubbles |
| In the critical thinking activity from this lab, what was the independent variable? | Color of the light source |
| In our experiment with fresh leaves, what was the dependent variable? | Number of bubbles |
| Part of the plant that houses photosynthesis | Chloroplast |
| Photosynthesis requires water, carbon dioxide and _____ to make _____ | Sunlight; Sugar |
| Mitochondria was where _______ takes place which is where plants metabolize sugar made from photosynthesis and turn them into _______ (energy) | Cell Respiration; ATP |
| ______ provides the energy that drives photosynthesis | Light |
| Without light, photosynthesis _____ | Stops |
| One way we can determine if photosynthesis is occurring is by looking for the emission of ______ from the leaf of a plant in the form of ______ | Oxygen; Bubbles |
| How many bubbles were on the leaf that was in the dark cabinet? | Few |
| How many bubbles were on the leave that was in the sunlight? | Many |
| Would the intensity of the light affect the number of bubbles? | Yes |
| Which would produce more bubbles, a 40W light or a 100W light? | 100 |
| Oxygen is a byproduct of ______, and fills the spaces in the leaf disk causing the leaf in water to _______ | Photosynthesis; Float |
| When the leaf was put in water, ]what substance is responsible or the leaf disk to float rather than remaining submerged? | Oxygen |
| To reduce algae growth i so you need to reduce the _____ of light or the amount of _____ in the light | Amount; Time |
| Two variables other than light intensity that would influence how quickly a leaf disk floats would be ______ and _____ | Water; Carbon Dioxide |
| Sunlight + C02 + H20 ----- 02 + C6H1206 | Photosynthesis |
| C6H1206 + 02 -------- C02 + H20 + ATP | Cellular Respiration |
