Presentation transcript:

Pollen Grain Development Formation of the Male Gamete

The Stamen is Diploid Microspore Mother Cells are found in the Anther

Meiosis 4 Haploid Cells /A Tetrad is formed Pollen Grains

Mitosis Each Pollen Grain now has two haploid nuclei (a) A Tube Nucleus (b) A Generative Nucleus

Each Species of Pollen is unique Exine = Outer Protective Layer Intine = Inner Protective Layer

Mitosis After Pollination the generative nucleus divides again The Tube nucleus forms the pollen tube The Generative Nucleus forms the 2 male Gametes
