|Explore||Explore Section: Plant Cells: Plant cells are eukaryotic. Eukaryotic cells have multiple chromosomes. Some Eukaryotic cells have a couple chromosomes, while some Eukaryotic cells have more than 100 chromosomes. All these chromosomes are protected by a nucleus. Eukaryotic cells also contain...|
|Research Question||Experiment 1: Question: Can we see how fast different liquids travel up the stem of celery (capillary action and transpiration)? Purpose: To figure out if the xylem transport different liquids- It if does, I think they will be transported more slowly because the celery isn’t used to them....|
|Predictions||1- We predict the liquid movement will stop because of the carbonation in the Coke. We think the lemonade will start making its way to the top then stop on its way up because it will accept the sugar at 1st but then reject it. Then, it won’t keep going up because of the sugar in the water....|
|Experimental Design||de from sugar, water and lemon juice. (add black dye) Fill cup with coke and water, and put dye in each flask (same amount of dye) Cut celery length so it is the same Put celery in each flask Come back at the end of Block (1 hour later) and take 1 piece of celery out. Then measure how...|
|Conclusion||Experiment 1: In conclusion, we have realized that celery doesn’t seem to take in anything other than water. The coke and lemonade went up about ¼cm before not going up further. Even though it didn’t take in the other liquids, they still didn’t alter the physical celery as much as the salt water...|
Farewell and Best Wishes
As this research project is now in the final stages of wrapping-up, we wish to thank everyone who participated in this inquiry; the students, mentors, teachers and others behind the scenes. We appreciate all of your efforts and contributions to this online learning community.
Scientific exploration is a process of discovery that can be fun! There are many unanswered questions about plants just waiting for new scientists to consider, investigate, and share.
After the end of the session, we will be updating the platform and archiving groups and projects, after which time new updates/posts will not be able to be added to projects or groups. Please come back and visit the PlantingScience Project Gallery anytime to view this project in the future. You can search the Gallery by keyword, team name, topic, or school name.
Good bye for now.
The PlantingScience Team
Thank you so much for your kind note. I also apologize for being unreliable with the Zoom connections--we have had some sickness at work this week and I have been dealing with this problem but I feel very fortunate to have worked with you this semester! I wanted to make sure you knew how impressive I thought your work was on this project--I really enjoyed your photos and sketches that enhanced your work. You also demonstrated strong scientific thinking skills. I hope that you and all your friends and family are safe and happy as we move into this Thanksgiving season and that the rest of your semester goes smoothly. Your team really stands out in terms of your diligence and creativity in your project!
Thank you Dr. Vrentas!
We really appreciated working with you! All your advice was really helpful and we enjoyed it greatly. One of our favorite parts of our experiment was examining the celery and making observations.
Thank you! -Some Humans (Yasmine, Jacob, and Stella)
I understand you are coming to the end of your journey with your project, and I will be planning on attending for the presentation on Friday.
I went through your poster content again and I had a few quick notes related to your presentation--just some things to think about as you describe your results, extending from our discussion:
--Based on what we discussed about salt water, how might we be able to explain the celery getting flaccid in that condition?
--How might this experiment relate to the water the plant is taking up in the ground? (in other words, what might be in that water?)
Nice work everyone! I hope these comments will help you to clarify things. Good luck on your presentations on Wednesday.
Hi Dr. Vrentas!
Thank you for taking the time and meeting with us, we really appreciate it! I just put our poster in the files section if you would like to take a look. We have fixed our poster based on the suggestions. Thanks for the recap on everything we talked about. If you have any other questions or suggestions we would love to hear them.

It was great to speak with you on Wednesday! I am glad we were able to connect on Zoom and I hope you have had a good week at school.
As a recap, we discussed a few things about your slides:
--The fact that mushy stems could be some bacterial growth over a couple of days, and that the bluish/greenish color was still probably the food dye
--The process of osmosis--water can flow out of cells to create a balance when the water around the cells is very salty. This means that the cells will shrivel up, and the celery will become "wilty."
--Water in the soil may have some other chemicals, like minerals (like our electrolyte water!) dissolved in it. Water with other dissolved chemicals can still move into the plant. But it can be complex, since there is a balance of water flows in and out of cells!
--The plant will need water for its cells, so that it can stand up straight and also because water is needed for the chemistry of life. The plant gets energy from a different source--it captures the energy from light in sugars through photosynthesis, and then the sugars are broken down in the plant cells through respiration to provide the plant with energy.
I know you were mentioning at the end that you might need some additional feedback--was it on the poster or the slides? I just wanted to check to make sure I was looking at the right place and answering the remaining questions that you had :)
Looks like you are in the final stages of your projects.
It’s great to see that teams from your school are wrapping up and posting conclusions. Enjoy the final stages of your project, and feel free to post any final comments or questions you have for your mentors.
Hi Dr. Vrentas!
All good, excited to meet with you on Wednesday! We wanted to update you on some of our information for our poster. We have concluded both our experiments with the celery too. I have put our google slides presentation in the files section if you would like to look at it.

I have been having some issues with getting the forum messages due to some of my messages going to spam, so I know I missed out on the opportunity to chat on Zoom last week. I apologize for this!! (Just to clarify--it is nothing wrong with the Planting Science portal, which is great--but my email).
So I wanted to make sure we had a chance to "meet" on video and so I made a video that talks about my background as a scientist and some of the things I like most about being a scientist. I hope it will be helpful to you--I wanted you to know that I have really enjoyed being your mentor this semester, that it is important to me, and that I want to make sure you have a chance to get as much as possible out of this experience!
**To find the file--you can go under the Files tab to the left and it is the new video. (I actually split it into three, to make sure it uploaded with the size.). If there are any problems with the video opening, I will work on sharing it in a different way that is consistent with the Planting Science rules.
I hope you had a fun Halloween! Did you have a costume? I must say I was pretty boring (no costume for me) but I saw some really cool plant-related costumes online. My favorite was someone who dressed up as a slug. Garden slugs can certainly cause havoc among vegetables...
Please feel free to let me know what questions you have.
We wanted to let you know that we have concluded our experiment. We will upload the slides with all of our information. Some of the results we got were very interesting. I will upload the some pictures too. We will have a draft of the poster we are making soon.
