Ferm Life Cycle Introduction:   Ã‚  Ã‚  Ã‚  Ã‚  This essay will discuss the fern life cycle as taught in biology lab. The essay will cover the basic process which we used to grow a fern. I will discuss the methods and the results of the lab exercise. Finally, I will discuss the evidence of the methods and results that were obtained . Methods and Results:   Ã‚  Ã‚  Ã‚  Ã‚  To begin our experiment we obtained a petri dish from our lab instructor which contained fern spores and the food they needed to survive. We then look at the spores through the micro scope. It was to soon to see anything but little green dots. We then put our petri dishes under a light until next week.   Ã‚  Ã‚  Ã‚  Ã‚   When we came in next week we observed our fern spores through the dissecting microscope. We looked to see if we could find anything germinating. We quickly noticed something that appeared like an air bubble squirting out something green. This was our fern spore which was germinating. Next, we removed a few of the germinating spores from the petri dish and put them under a compound microscope scope. We found the spore wall and observed how the developing gametophyte had broken through the wall, as instructed by our lab manuals. One could also identify the chloroplasts with in the cell. We then put up our dishes for another week.   Ã‚  Ã‚  Ã‚  Ã‚  The third week of our fern lab we identified the difference between male and female gametophyt...
