Answer:-
For Plant Diversity, Indicate whether the following structures are part of the gametophyte or sporophyte generation....
draw a diagram the parts of alternation of generation; plant stages (gametophyte & sporophyte), diploid, haploid, mitosis, meiosis, spore and gamete release, fertilization
A Name this plant: C. identify the sporophyte identify the gametophyte A. Name this plant B. Identify the sporophyte Identify the gametophyte A. Name this plant: B. c. identify the sporophyte identify the gametophyte 50. A Name this plant B. Identify the sporophyte C. Identify the gametophyte
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...
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.
A pollen grain is a(n)________ a. male gametophyte b. sporophyte c. integument d. female gametophyte
Name the gametophyte structure and the sporophyte structure of both bryophytes and ferns. Also know whether they are haploid or diploid, and which is the more easily recognized (dominant). Be able to tell which gametangia the reproductive structures of moss and ferns are (archegonium or antheridium). Know the terms: rhizoid, rhizome, gemmae cups, prothallus, sorus, sporangia, alternation of generations (explain what it is)

BIOL 1020 Homework Evolution & Natural Selection 4 NATURAL SELECTION: 1. In your OWN words, explain what natural selection is. What is required? What is the result? 2. True or false? For natural selection to work, a population must have genetic variation. Explain your answer. 3. List three sources of genetic variation in a population. Identify which sources are most important for asexually reproducing organisms. Which method is most important for sexually reproducing organisms? 4. List three mechanisms which cause...
