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...

What is true about the life cycle of a land plant? 1. The gametophyte produces spores by meiosis. 2. The life cycle is entirely haploid, so the sporophyte phase does not exist. 3. The sporophyte produces spores by mitosis. 4. The sporophyte produces spores by meiosis. 5. The gametophyte produces gametes by meiosis.

Sketch the lifecycle of a bryophyte (alternation of generations). Place the following labels on the sketch: sporophyte, gametophyte, gametes, spores, mitosis, meiosis, diploid, haploid, fertilization, zygote. Sporophytes are attached to which sex gametophyte? _______________________ Are spores haploid or diploid? ______________________ Which life form, gametophyte or sporophyte, undergoes meiosis? ______________________ In mosses (and all bryophytes), which is the dominant life form, sporophyte or gametophyte? ____________________ A) Is the gametophyte of the fern directly protected by the sporophyte? B) Where could you...

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...
