The purpose of this lab is to examine cross sections from the leaves of C3 and C4 plants and to determine the morphological differences between them while relating those differences to their metabolism. In C3 plants the carbon dioxide is first incorporated into a 3-carbon compound. Their stomata are open during the day and photosynthesis takes place throughout the mesophyll cells. In comparison C4 plants, the CO2 is first incorporated into a 4-carbon compound. Their stomata are open during the day and photosynthesis takes place within the inner cells. C4 plants undergo carbon fixation and C3 plants undergo the Krebs cycle.
This experiment is specifically for undergraduate students who have previous knowledge and background on the process of photosynthesis within C3 and C4 plants. The

Take the mounted section to a microscope for viewing. 8. View the slide under bright field or phase contrast of the microscope, then blue light.
9. Repeat steps 2-8 under “How to Cut and Mount Sections” for the Tradescantia species.
View the Epidermal Cells of Muhlengbergia and Tradescantia Species
1. Obtain one leaf each from the Muhlengbergia and Tradescantia Species.
2. Place a few drops of tap water onto two clean slides.
4. In lengthwise form, tear the leaf.
5. Use the razor to cut some of the out-sticking epidermal cells from each torn end.
6. Transfer to the section to the slide.
7. Add small drops of water onto the slide then cover with a cover slip. 8. Take the mounted section to the microscope for viewing.

Conclusion
After completing the experiment a conclusion must be drawn. Depending on the results, your hypothesis will or will not have a correlation.
We can assume from the picture below, that the Tradescantia species will be concluded as a C3 plant because of the chloroplast being within the bundle sheath and the Muhlengbergia Species will have a relation to a C4 plant due to its chloroplast being located within the bundle sheath and also the

    Determining the cell shapes will help with the process of elimination organisms. Under microscopic examination for my unknown 16 broth, it appears to be a coccus shape and a gram positive. Gram staining can determine cell morphology, size, and arrangement. In a positive gram stain, a primary stain called crystal violet is used to stain the cell. For every new stain, mordant, decolorizing agent, and counterstain, it must be rinsed with distilled water.…

    Not only the temperature but the cell type and size, and also how much nutrients is available. The organism that we studied was germinating mung bean seeds. We used a system called respirometer which includes a test tube that is to be filled with the seeds until approximately 3 cm before the top. Other parts that were included was the syringe, and a 1ml pipette, with both the syringe and the pipette threaded through a cork cap that is placed onto the test tube. We are trying to measure the respiration rate.…

    Lenses and vitreous body were removed from the embryos from day 6-20. The vitreous body and lens are then transferred to a petri dish where they would be separated by doing a careful disection. Dr. Mark Adeelman donated the rhodamine-123 for the study which was used a methanol stock. This stock was used for the fluorescent probes. In order to be able to examine the lens with the confocal microscope one needs to stain it with the fluorescent dye.…
