How does the development of the embryo sac in flowering plants differ from oogenesis in humans?

 

In this question you should compare the events that occur during either process up to and including the products of each process.

Development of embryo sac Oogenesis
Develops primarily by mitosis from dedicated haploid functional mega spore cells. Development involves meiotic and mitotic divisions of diploid germ cells.
Results in a cell with 8 nuclei Results in a mature egg cell with only one nucleus.
No polar cells are formed 3 polar cells are formed but atrophy (degenerate)
No yolk sac is formed A yolk sac is formed.
