Plant Diversity The scales of the female cones bear ovules, which enclose the female sporangia. Cells in the female sporangia also undergo meiosis to produce spores. One of the spores from each meiotic division develops into a female gametophyte by mitosis. As the pollen germinates and produces sperm nuclei by mitosis, the female gametophyte produces an egg. One sperm nucleus reaches the egg through the pollen tube and fertilizes it. Notice in Figure 6 that the male gametangium has been...

Using the information you have gathered, address the Focus Question: What is the life cycle of a flowering plant? Draw a circular diagram of the life cycle of a flowering plant. Be sure to include the five structures, listed in Table 1, in the proper order (gametophyte, sporophyte, zygote, spore, gamete). Indicate whether each structure is haploid or diploid and the process by which each structure is produced by the previous structure. You should draw male and female gametophytes and...

Describe (in words), the life cycle of an Angiosperm starting with a seed that is germinating right now, following that seedling though its life until it produces a seed of its own that will complete one full generation. Be sure to explain the steps involved in this plant’s life cycle related to its alternation of generations. Describe the reproductive structures produced along the way, using proper terminology that we have repeatedly discussed in the context of plant life cycles. Be...
