| Research Question | How does the increase of salinity (NACL) affect the female to male ratio that is produced, and how does it affect the gametophyte? |
| Predictions | Our prediction is that increasing the salinity will produce more females than males. We think this because as we add salinity we will stress the gametophyte then it will fertilize to self-creating females. |
| Experimental Design | Our plan is to have four petri dishes with all different salinity levels. We figured out that c ferns live in 0.5% salinity level, so we have one dish at 0.5%, 1.0%, 1.5%, and 2.0%. Our independent variable is going to be the how much salinity we add to each petri dish. Our dependent variable is going to be the male to female ratio. |
| Conclusion | Our claim is that when you increase the amount of salinity in the c-ferns environment the c-ferns will produce more females than males. When adding salt to the environment we stressed the gametophyte and produced more self fertilizing females. |
