BIOL 2010 Quiz: Embryogenesis
Document Summary
The haploid spores will undergo mitotic division and result in vegetative and generative cells. The complexity is that usually you would think about cells as distinct separate cells but in fact if you think of the maturation process they are both embedded and look like they are in the same cell. Maturation results a tough outer coating: things get strange in plants because its not a single fertilization event that occurs- its actually 2 and is known as the double fertilization. The triploid endosperm then surrounds the developing zygote: mitosis results in generative cell which then undergoes a 2nd mitosis, above- microgametogenic process. Megagametogenic process: fairly similar complexity associated with it- occurs in the angiosperms, this process is the eventual formation of an 8 nuclei embryo sac. All of this occurs within a well defined and protected environment in the carpel. The 2 cells on either side of it are known as synergid cells.
