|Explore||Pollen is really important in plant reproduction. Pollen is produced in the stamen and then transported to the stigma. Below the stigma is the ovary that holds the ovule. Once on the stigma, the pollen grows the tube which makes it to the ovule. This becomes the seed and the ovary becomes the...|
|Research Question||Does the amount of sucrose affect pollen tube growth?|
|Predictions||We predict that 20% sucrose will make more pollen germinate. We think this because when we grew pollen tubes in 10% they grew so we think more sugar would mean more growth.|
|Experimental Design||We will have five dishes with five straws to go with them. We are going to have 5%,10%,15%,20% and 0%. That is the amount of sugar water we will be putting in each. At 0% we will just put water in it. We will be measuring the growth of the pollen.|
|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?|
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. You have until Tuesday, April 25, 2021, to post ALL of your updates, comments, and goodbyes. 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
Good afternoon, I am grateful for all of your help! Thank you for taking your time out of your day to help us. We appreciate it a lot. We will be signing off. I hope you all have a nice day. Stay warm!
Hi Team, I just want to say I am very impressed with the work you did. I’m planning to recommend your team for recognition for planning an unusually interesting experiment. And one that may also be useful for devising more experiments along the same lines. Good luck with your future endeavors and I honestly hope some of you will become scientists. You’re talented.
Good afternoon, we I just want to tell you that we a living and we just want to tell you Thank you for taking your time and working with us. We greatly appreciate it. Have a nice wonderful day!
Hi team, interesting results! Thanks for the report. Why did you originally think that 20% sucrose would have the highest germination rate? Remember that sucrose is energy for that the pollen can use to produce the tube!
I think this week you are wrapping up the module, so I just wanted to thank you for really using your scientific and critical thinking skills; I hope you'll continue to stay curious! I also wish you the best the rest of the school year and success in your future endeavors!
It looks like the problem is resolved and everything should be back to normal. Please feel free to resume posting, and do let us know if you experience any issues posting to your projects.
We are aware of some technical issues with the platform, leading to an issue with posting to project pages and issues with users' dashboards. We are working diligently with our developer to resolve them as quickly as possible. Please be patient and keep checking your projects so you can post your hellos, updates, reports, thank-yous, and goodbyes.
Good afternoon! Today we checked our project on pollen tubes and we found out that 50% sucrose produces the most pollen tubes. We were surprised because we thought that 20% sucrose would produce more.20% was the same as 10%. they both made 3 pollen tubes.
good afternoon today we check ours pre experiment to see if pollen grains and we count them and they were 40-50 more thank you and have a good day
Good afternoon, today we planned an experiment with growing pollen. We are going to use sugar water and water to help it grow. We are going to put different amount of sugar water drops. We are going to do one with no sugar water just with water. That one is going to be our control. The consent variables are the pollen type, amount of water, plant, and temperature. We are measuring the percentage of germinate pollen.

Hi Team! I think you’re seeing some of the natural variation found in nature in general and you’re asking good questions! Nice photos you posted! I’m wondering myself now if pollen is always found in a round shape. We should look this up.
Good afternoon today we were looking at red mable and dandelion, hairy bittercress and spice bush and the pollen inside of them. How come pollen is little circle of balls? How come there are more in some flowers than barely to none in others. Do they produce differently?
Hi Keona, Jennifer and Francis, are you thinking of a project for your experiment now?
Hello, today in class we learned about pollution. We think the Alstromeria self-pollinate because it is attractive. Chickweed is most likely to be pollinated by wind because the stigma was out and sticky. Carnation is most likely to be pollinated by an animal because it is bright and attractive. We think the Carnation is a female.
