The effects of ammonium nitrate on c-fern spore germination

Introduction:

Organisms need their own set of nutrients. These nutrients are what help the cell survive so that the whole organism could survive. Organisms have their own set of nutrients. On earth there are three domains of life. These domains are the bacteria, Archaea, and eukarya (Brooker et al. 2013) most of the cells that are being researched and examined are cells in the domain Eukarya because cells in this domain usually exists in a multicellular complex. In the domain eukarya, the genus that was examined in this lab was Ceratopteris, which is also called c-fern; this plant is used in research to see how plant growth is affected by various changes that affect plant growth. (Lloyd, 1973) The reason that c-fern is used to do research is because of it’s developmental process. The reason why their life cycle is so unique is because it has a biphasic life cycle that has two independent diploid and haploid generations. (Hickok et al., 1995) This is useful because the haploid and the diploid can be isolated which will provide information on how each variable effect each different stage during each life cycle. (Hickok et al., 1995) another advantage of why c-ferns are used in research is because of their short life cycle. After inoculation, germination occurs in the following 3-4 days and full sexual maturity occurs between 6-8 days after germination. After one to two weeks, roots and leaves start to appear on the diploid sporophyte. (Hickok et al., 1995) these are the main reasons why c-ferns were chosen to see the effects of nitrogen on.

All plants including c-ferns need nitrogen in order to function properly. These plants need nitrogen because it is a main com...

...atistical analysis was used to understand the data that was collected. The f-test was the first statistical analysis that was used in order to know if the next step would use the t-test or Welch’s approximate t-test.
