3.1.14 Oogenesis

Oogenesis

Female process of meiosis. Produces eggs

T or F? Oogenesis produces 4 ova

F. While oogenesis creates 4 cells at the end of meiosis, 3 fail to be develop into ovum. They are called polar bodies and they are an example of unequal cytokinesis

What are polar bodies?

Small cells that bud off from an oocyte during oogenesis

What happens to polar bodies?

They do not develop into ova. They eventually disintegrate.

What is the function of polar bodies?

They serve as a container for divided chromosomes during meiosis 1 and 2.

oogonia/oogonium are

diploid cells

What do oogonia do?

Repeatedly undergo mitosis to build up the number of oogonia in the ovaries.
Grows into larger cells called primary oocytes

follicle cells

somatic cells that surround the oocyte and nurse cells during egg development
