    • BY 124 REVIEW
      Exam One
    • Question 1
      Review the life cycle of a typical moss plant by filling in the following blanks:
      The dominant generation is the a)_____. Female gametophytes produce eggs in the b)______. Male gametophytes produce sperm in the c)________. Sperm d)_______ through the damp environment to fertilize the egg. The zygote remains in the archegonium and grows into the e)______, still attached to the female gametophyte. Spores are formed by the process of f)______ in the g)______. When shed, spores develop into the h)_______.
    • Question 2
      Adaptations for terrestrial life seen in all plants are
      chlorophylls a and b
      cells walls of cellulose and lignin
      Sporopollenin, protection and nourishment of embryo by gametophyte
      Vascular tissue and stomata
      Alternation of generations
    • Question 3
      Bryophytes differ from all other land plant groups because
      Their gametophyte generation is dominant
      They are lacking in gametangia
      They have flagellated sperm
      They are not embryophytes
      Of all of the above
    • Question 4
      If a plant’s life cycle includes both a male and a female gametophyte, the sporophyte plat must be
      Heterosporous
      Homosporous
      Homologous
      Analogous
      Megasporous
    • Question 5
      [Life cycle of a pine]
      Describe a pollen cone and the formation of a male gametophyte.
    • Question 6
      [Life cycle of a pine]
      Describe a ovulate cone and the formation of a female gametophyte.
    • Question 7
      Name the four whorls of modified leaves that make up a flower.
    • Question 8
      What does a seed consist of?
    • Question 9
      List the four phyla that are considered gymnosperms
    • Question 10
      Where would you find a microsporangium in the life cycle of a pine?
      Within the embryo sac in an ovule
      In the pollen sacs in an anther
      At the base of a sporophyll in a pollen cone
      On a scale-like sporophyll found in an ovulate cone
      Forming a seed coat surrounding a pine seed
    • Question 11
      In which of the following groups do sperm no longer have to swim to reach the female gametophyte?
      bryophytes
      ferns
      gymnosperms
      angiosperms
      Both c and d
    • Question 12
      An example of coevolution is
      • A flower with a nectar tube that is the length of its pollinator’s proboscis (elongated appendage from the head/sucking organ)
      • The synchronization of nutrient development and fertilization resulting from double fertilization
      • Win pollination in conifers
      • The evolution of seeds in both gymnosperms and angiosperms
      • The development of alternation of generations independently in land plants and some algal groups
    • Question 13
      Which types of plant cells are dead at functional maturity?
    • Question 14
      Which types of plant cells lack nuclei at functional maturity?
    • Question 15
      Starting from the outside, place the letters of the tissues in the order in which they are located in a woody tree trunk.
      Primary phloem
      Secondary phloem
      Primary xylem
      Secondary xylem
      Pith
      Cork cambium
      Vascular cambium
      Cork cells
    • Question 16
      Explain the contribution of each of the following to the long-distance transport of water:
      Transpiration:
      Cohesion:
      Adhesion:
      Tension:
    • Question 17
      Epiphytes
      Have haustoria for anchoring to their host plants and obtaining xylem or phloem sap
      Are symbiotic relationships between leaves and fungi
      Grow on other plants and obtain nutrients from their hosts
      Grow on other plants and do not obtain nutrients from their hosts
      Are able to fix their own nitrogen
    • Question 18
      What function does double fertilization serve?
    • Question 19
      Name two important messengers in plant hormonal systems.
    • Question 20
      What kind of root growth do auxins promote? What kind of charge does auxin have? How are auxins transported in plants?
    • GOOD LUCK STUDYING!
