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
