Mitosis & Meiosis

Meiosis is the process of cellular division necessary for sexual reproduction in eukaryotes. The number of sets of chromosomes in the cell undergoing meiosis is reduced to half the original number. The cells produced by meiosis are either gametes (the usual case in animals) or otherwise usually spores from which gametes are ultimately produced (the case in land plants).

Mitosis is the process of cellular division. The cycle starts when a cell has previously replicated each of its chromosomes, separates the chromosomes in its cell nucleus, into two identical sets of chromosomes, each set with its own nucleus. It is followed immediately by cytokinesis. 

 

Plant & Animal Cells

In class, we observed dog fleas and plant cells with a microscope. We also created our own slides and observed cheek cell samples taken from our fellow students.
