Title:
Reproduction and Development I: Microscopic Examination of Cells at Various Stages of Plant Meiosis
Objective:
To examine the cell at various stages of the meiotic cell cycle microscopically.
Apparatus and Materials:
Lily Anther early Prophase c.s.
Lily Anther late Prophase c.s.
Lily Anther First Meiotic division c.s.
Lily Anther second Meiotic division c.s.
Lily Anther Pollen Tetrad
Binocular microscope
Procedures:
1. Two or more photographs with each view showing at least 2 different meiotic phases were captured.
2. For the two best photographs captured, labelling and annotation in Microsoft Word file was done.
For each photograph:
●At least 2 different meiotic phases were labelled.
● Annotation below the labels of meiotic phases were made.
3. The photograph was printed out in colour and submit.

Results:
Anaphase I
-homologous chromosome separate
-one chromosome moves toward each pole
-sister chromatid remain attached at the centromere  
Anaphase I
-homologous chromosome separate
-one chromosome moves toward each pole
-sister chromatid remain attached at the centromere  
Telophase I
-consists of two sister chromatids
-new nuclear envelope form around the two clusters of chromosome
-haploid set of chromosomes

Discussion:
Meiosis is a nuclear division mechanism that occurs in immature reproducing cells of sexually reproducing eukaryotes. Meiosis precedes the formation of gametes or spores and it is the basis of sexual reproduction. In humans and all other mammals, the gametes called sperms and eggs develop from immature reproductive cells. Specific cells in the mature diploid phase of the plant life cycle undergo meiosis, but this does not produce gametes. Instead, the haploid cells are known as spores. Since the diploid phase of the life cycle produces spores, it...
