Understand the process of oogenesis, which is the development of mature egg cells (ova) in females.
Recognize that oogenesis begins with a type of stem cell called oogonia, which are the precursor cells in the ovaries.
Learn that oogonia undergo mitosis to increase their numbers and then begin meiosis to form primary oocytes.
Note that primary oocytes are arrested in prophase I of meiosis until puberty, when they resume meiosis during each menstrual cycle.
Differentiate between primary oocytes and other cell types such as secondary oocytes, zygotes, and spermatogonia, understanding that oogonia are the cells that give rise to primary oocytes.
