Question 22 (2 points) Male gametophytes produce sperm in OB) Archegonia OC) Gametophyte D) Sporophyte A) Antheridia
In ferns, both the gametophyte and sporophyte are physiologically capable of surviving on their own. Which of the following are reasonable hypotheses for why vascular tissues are present only in the sporophyte generation? Select all that apply. There is no advantage for the gametophyte to grow tall, because fern gametophytes typically produce only male or female gametes at any one time There is no advantage for the gametophyte to grow tall, because gametes must be produced near the ground where...
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...
Q: Males cones are called staminate cones, where on the tree are they found? Each scale (microsporophyll) on the staminate cone bears a microsporangium that produces pollen grains (male gametophytes) Q: What do we call the pine's male gametophytes? Procedures 30.3 & 30.4 Phylum Coniferophyta → See figures named below in parenthesis from lab book Female ovulate cones are on upper branches of pine trees; each produces megaspores that undergo mitosis into a megagametophyte which, together with its surrounding tissues,...
