| Explore | Our group knows that plants produce their own food, they're autotrophs. They produce food from a process called photosynthesis. Now we know that c-ferns can be hermaphrodites or they can also be male. They ferns are first grown from spores. What is an in depth description of how plants reproduce? |
|---|---|
| Research Question | How will the salt levels of water affect the sexual maturation of c-fern spores? |
| Predictions | If we add salt to the water, then the sexual maturation of the spores will occur later because c-ferns are fresh water plants. |
| Experimental Design | Independent Variable: the salt levels of the water (1%, 2%, 3%) Dependent Variable: the number of days the spores took to sexually mature Constants: dishes, light, amount of water, type of plant |
| Conclusion | The salt did not majorly affect the sexual maturation of the spores. The 1% solution was the first to start the process of sexual maturation, and the 2 % followed closely after. The 3% solution was the last to mature, and the control started sexual maturation between the time of the 2% and the 3% solutions |
