Ques:Answer the following question given this paragraph: Watch this video (http://openstaxcollege. org/l/pollen_release) to see a cedar releasing its pollen in the wind. Female Gametophyte The female cone also has a central axis on which bracts known as megasporophylls (Figure 32.10) are present. In the female cone, megaspore mother cells are present in the megasporangium. The megaspore mother cell divides by meiosis to produce four haploid megaspores. One of the megaspores divides to form the multicellular female gametophyte, while the others divide to form the rest of the structure. The female gametophyte is contained within a structure called the archegonium. Q: What does the megaspore mother cell produce after meiosis division? Choices: - four diploid megaspores - two diploid megapores - two haploid megaspores - four haploid megaspores A:

Ans:
four haploid megaspores
