Study Notes
Male Gametophyte Development in Pollen Grains
- Pollen grains form in anthers.
- Each anther has 4 microsporangia (pollen sacs).
- Microsporocytes (diploid cells) are within the microsporangia.
- Microsporocytes undergo meiosis producing 4 haploid microspores.
- Microspores undergo mitosis to create a haploid male gametophyte.
This gametophyte consists of 2 cells: a generative cell and a tube cell.
- The spore wall, from both the microsporangia and anther, has a unique species-specific pattern.
