Introduction
Research Question
Generally, we are interested in the relative time spent in different stages of the cell cycle by different organisms. Specifically, we can use our ability to recognize the characteristic chromosomal structures seen in different stages of mitosis and interphase to count these in prepared slides from particular orgamisms, onion (Allium) root tips, whitefish embryos and nematode (Ascaris) embryos.

Experimental Design
In the final report, each individual student should identify and discuss the range and sufficiency of all relevant variables, address the specifics of the methodology of the design what tools, techniques were used, including any assumptions or simplifications that were made, and anticipate the uncertainties that may arise and what steps were should be taken to avoid or minimize them.

Data Tables (in progress)
These spreadsheet documents are designed collectively by students in each section of the class, For a final submission, each student is expected to arrange/modify/annotate the tables to include a logical and complete presentation of raw and processed data. Refer to the IB rubric for Data Collection and Processing for guidelines on what to include in a complete table.
