17. During which phase of mitosis does the nuclear envelope disappear?






18. During which phase of the cell cycle does DNA replication occur?






19. Seeds are not protected by fruit and they do not have flowers - do not have shell around seeds - reproduce by releasing pollen into the air to make available to the ovule in the megaspores - causing fertilization
