On this page, we mainly focus on the cellular aspects of cell division. The genetic elements of the cell cycle are looked into on the page "Cell Cycle and DNA Replication". The button on the right makes it convenient for you to switch to that page.
This video may be helpful when working on the tasks provided in the worksheet "Cell Cycle". But the worksheet reaches beyond the content of the video.
To download the worksheet merely press the following button.
How fast do cells divide? And how do specific factors influence this process? The virtual lab “Reproduction Rate of Single-Celled Organisms” is tailored to investigate these questions. It also trains your data collection and data evaluation skills. It offers microscopic photographs of yeast culture samples which have been grown under different circumstances and for varying lengths of time. It is your task to count the cells present in the sample, visualize your data, and interpret your results.
Under certain conditions, there are simply too many yeast cells to count. The sample needs to be diluted. You will have to carefully choose the dilution factor you want to work with in order to balance the feasibility of your data-collection and the reliability of your results.
