terrestrial plant characterized by having megaphylls and motile
sperm
____________________ 14 Flower in
which the ovary is embedded in the receptacle
____________________ 15 Collectively
the carpels are known as:
____________________ 16 The region
of the fruit to which the ovules are attached
____________________ 17 Two bracts
found in a glass floret
____________________ 18
____________________ 19 immature
male gametophyte in seed plants

terrestrial plant characterized by having megaphylls and motile
sperm
____________________ 21 transfer
of pollen
____________________ 22 heterosporus
terrestrial plant characterized by having microphylls
____________________ 23 female gametangium
in which the egg is protected by a jacket of sterile cells
____________________ 24 an elongated,
spindle-shaped, sterile, hygroscopic cell
____________________ 25 a small mass
of vegetative tissue functioning in asexual reproduction in a
gametophyte
____________________ 26 the meiospore
of a vascular plant which gives rise to a female gametophye
____________________ 27 the condition
of producing only one sort of spore
____________________ 28 membranous
growth of the epidermis of a fern leaf that protects and covers
a sorus
____________________ 29 an algal-like
filamentous growth which is the germination product of the meiospore
in some bryophytes
____________________ 30 common name
for all vascular plants
____________________ 31 a cluster
of meiosporangia
____________________ 32 the extension
of the gametophyte in the thallose liverwort, Marchantia, which
contains the antheridia
____________________ 33 the organism
essential for the growth of the underground gametophyte in club
mosses
____________________ 34 branching
pattern typical of whisk ferns
____________________ 35 the spore
bearing leaf in Lycopodium
____________________ 36 the type
of stem found in most temperate ferns
____________________ 37 the
type of gametophyte typical of all hornworts
____________________ 38 immature
sporophyte which develops in the archegonium in all bryophytes
and pteridophytes
____________________ 39 the two hygroscopic
structures in a moss sporophyte
____________________ 40
II. The following statements give the characteristics
of the sporophytes and/or the gametophytes of:

Put the letter of the appropriate genus or group
in space provided
________ 41 the main plant has a stem
which is a rhizome and sporagnia borne on the back of fronds
________ 42 parasitic sporophyte when
mature
________ 43 thallose gametophyte
________ 44 a dependent leafless axis,
consisting of a foot, seta, green capsule at first, and has several
specialized structures
________ 45 horizontal stem, upright
branches, sporangia on sporophylss similar to vegetative leaves
but grouped together at top of stem
________ 46 upright stem, lacks roots,
small leaves which are scale-like, sporangia in axil of leaves
________ 47 mostly prostrate leafy
stems, sporophylls in 4-sided strobili at upper end of stem, heterosporous
________ 48 hortizontal stems, upright
branches, sporophylls differing from leaves grouped at upper end
of stems
________ 49 independent; small leaves
on short rigid stem with cells which strengthen and cells which
are sieve-like
________ 50 enclosed in spores walls
________ 51 small heart-shaped thallus,
one or two cells in thickness; sporophyte dominant
________ 52 gametophytes with fungi
________ 53 gametophytes with leaf-like
and stem-like structures.
________ 54 immature sporophyte within
venter
________ 55 meiospores dispersed out
of meiosporangium by hygroscopic structures
________ 56 meristem composed of meiocytes
III. In the space provided, give the ploidy number
(i.e. N, 2N, 3N, 4N, 5N, N+N etc.) for the following structures
or plants
______57. in a plant with all the nuclei in an embryo
sac being 2N, the ploidy number of the endosperm
______58. nucellus
______59. megasporocyte
______60. megaphyll
______61. integument
______62. staminate cone scale
______63. the petals in a flower with parts in 5's
______64. gemma
______65. whorled microphylls
______66. archegonium in a whisk fern
______67. cotyledons
______68. companion cells
______69. calyptra
______70. seed coat
IV. How do pollen grains differ from spores or
sperm?
V. Do gemmae differ from meiospores? Defend
your answer.
VI. In the space provided diagram a longitudinal
section through the structure for the plant indicated. Label
all parts.
VII. The following genotypes are found in plants. Each letter,
regardless of whether it is capitalized or lower case, represents
a gene found in a chromosome; the capital letters represent dominant
genes, the lower case represents recessive genes. The same letters
represent homologous chromosomes. The total number of chromosomes
represented are all the chromosomes found in this particular plant.
You have studied life cylces in the bryophytes, pteridophytes,
gymnosperms, and angiosperms.
In which portion of the life cycle and in which group of plants
could the following genotypes be found? (Remember none of the
plant groups as well as all of the plant groups are possible as
an answer)
