Work on this next!
What do we know about plants from our experiences outside of school? What have we discovered in class and background research? What questions about plants interest us?
|Research Question||How can we impact the haploid generation of C ferns?|
|Predictions||What are the possible outcomes of our study given the variables we are working with? What is our explanation for why and how we think this will happen?|
|Experimental Design||The plan for our experiment is to have four petri dishes, one control, one with packed with gametophytes-creating limited space, one with the gametophyte spread out, and the last one will be isolated, the only one in the dish. We are trying to see if we can induce asexual reproduction with the...|
|Conclusion||What claim can we make from our experiment? What are possible explanations for our results? How do the data we collected and our reasoning with scientific ideas support our claim? What future experiments could be done to expand on the results of this experiment?|
Dear teachers, mentors, and student scientists,
Thank you all so much for the time and dedication you have devoted to these projects over the last few weeks. Ms. Parfitt and Ryan are truly dedicated educators, bringing science and enthusiasm to the classroom. The scientist mentors have done an excellent job being adaptive, interacting with their groups, and helping to do good scientists. And finally, the students have done a great job asking questions, collecting data, and taking care of their ferns! Great job everyone, I hope that this experience has taught you that plants [ferns] are some of the most interesting organisms in biology.
All the best,
Laura, scientist liaison
Thank you for helping us through this experiment. This is, unfortunately, our last day on the website so we can no longer communicate or upload any updates for the project. Our hypothesis proved to be true, whereas the Hermaphrodites ended up self fertillizing, and we thought you would know so we uploaded our final photos of it for you to see. once again, thank you for all the help, it was much needed!
Mack, Caitlyn, and Maddie.
The arrows aren't relative to the hermaphrodites, it is just a part of the dissecting scope that we couldn't move away. The Hermaphrodites are very healthy today, we are seeing new and healthy sporophytes. We will keep you updated.
We added some photos of what we have been seeing. Some of the Hermaphrodites are sprouting. As you can see in the photos
Update: The brown hermaphrodite was not a hermaphrodite. It was a male and was immediately removed. We have replaced it with a healthy hermaphrodite and the experiment continues.
The Hermaphrodites have grown in both size and population. We have plucked 8 hermaphrodites from the Control dish, putting 4 in the second one, 3 in the third one, and 1 in the fourth one. Over the next day, we have noticed two of the Hermaphrodites have turned Brown. The ones that are turning brown are ones that we have transported suggesting damage while we moved them.
Yes! We aren't expected to see any hermaphrodites or males until next week but we are continuing to look out for them. And the picture that was just uploaded was what we saw in the microscope today.
Great! So you will know the antherigen has been released when you can identify males on your plate, correct?
We will be extracting the hermaphrodites after they release the antheridiogen because we will need to have males in our control. Right now we have them all in one dish, we're using it as a harvesting dish until we pluck out some hermaphrodites.
Thank you for the article.
The article I uploaded contains good background information about the role of the antheridiogen in sex determination. The analysis of the results may be difficult to understand because you don't have the necessary knowledge in statistics. So, don't get frustrated; read the abstract and introduction; ignore materials & methods and results sections; examine figures 1 and 2 and read the discussion. Discuss among yourselves what you understand from reading the article and write down the questions you have. Post your questions and we will try to answer them. I hope the article helps.
Maddy said you would take out the hermaphrodites BEFORE antheridiogen is released. How do you know when the antheridiogen is released?
Looking more into this project, our question is is if we can see into the Hermaphrodite to Male ratio to determine if our Hermaphrodtie will be able to reproduce asexually through isolation processes. Are there any resources that would help us understand this better? Also, Antheridiogen occurs when the first Gametophyte appears, the Hermaphrodite will then release this antheridiogen that will change the sex of the males. We will be extracting the Hermaphrodites from the males BEFORE antheridiogen is released.

Hello Fern Avengers,
I read your experimental design. However, it isn't clear to me what your question is. Is it that you want to know if spore density affects the germination of spores? or is it that you want to know if spore density affects the gametophyte sexual determination? What do you think antheridiogen does? I feel you need to be more specific with your question and formulate the hypothesis. I suggest you get together and work on the question and hypothesis.
I look forward to hearing from you,
