In the ovary, the diploid megasporocytes undergo meiosis
2
Q

3
Q
What is the third step in the stamen?
A
the driving megastore divides three times
4
Q
What is the 4th step in the pistil?
A
the megaspores that divided PRODUCE 8 haploid nuclei
5
Q
What is the 5th step in the pistil?
A
the cytoplasm divides producing separate cells
6

• the other nuclei turn into separate cells
