Question 49 Which of the following is true concerning flowering plants? The gametophyte generation is what we see when looking at a large plant. The sporophyte generation is not photosynthetic. The flower includes sporophyte tissue. The gametophyte generation is dominant. The sporophyte generation consists of relatively few cells within the flower. In living conifers, microscopic male gametophytes should be found inside O ovulate cones. O an archegonium. ovaries. O pollén cones. O sporophylls.
Plants 1 4. The gametophyte generation contains both an archegonium and an antheridium. What is produced by each structure, and what is the function of each structure? What must happen for the life cycle to enter the sporophyte generation?
