Effects of Meristem Removal and Auxin Concentration on Coleptile Cell Growth

[rosie_burk]

auxins experiment Thanks :)

What would you expect to happen when you removed the meristem from 10 coleptiles, then placed five in water and the other five in auxin concentration of (2mg/ml)?

What would you notice about the number of cells for each section?

Welcome rosie to PF forums! If you have not already taken a look around, take some time to do so. You will notice there a lot of interesting and informative discussions and knowledgeable folks here who can help guide you through questions and discussion.

Your question about auxins is very interesting.. It looks like homework.. If so, it belongs under another topic on the forum .. here

Once there, I recommend reading through this https://www.physicsforums.com/showthread.php?t=94384. It helps clarify how to go about posting queries. If you like we can have this auxin post moved there.

Based on previous research and knowledge of plant growth and development, I would expect that removing the meristem from the coleptiles would result in a decrease in cell growth and division. The meristem is responsible for producing new cells in plants, so its removal would likely inhibit cell growth.

As for the two different environments (water and auxin concentration of 2mg/ml), I would expect to see a difference in cell growth between the two. Auxin is a hormone that promotes cell elongation and division, so the coleptiles in the auxin concentration would likely have more cells compared to those in water.

Specifically, I would expect to see a higher number of cells in the auxin-treated coleptiles compared to the water-treated ones. This is because the auxin would stimulate cell division and elongation, leading to more cells being produced. However, it is important to note that the concentration of auxin used may also play a role in the results. If the concentration is too high, it could have negative effects on cell growth.

Overall, I would expect to see a significant difference in the number of cells between the two groups, with the auxin-treated coleptiles having a higher cell count. This experiment could provide valuable insights into the role of meristems and auxin in plant growth and development.
