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...

Which of the following statements accurately compare the cross-sections of these two types of plants? Choose all that apply. In monocots, xylem cells are larger in diameter than phloem cells, but the opposite is true for eudicots. Monocots have pith in the center and cortex near the stem surface; eudicots do not. Monocots have vascular bundles scattered in the stem; eudicots have theirs arranged in a ring around the outer part of the stem. Both stems have epidermal cells on...

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.
