answers ) gametophyte Where do meiosis
and syngamy take place in the fern life cycle? ( correct
answers ) What phase of the fern life cycle is dominant? ( correct
answers ) sporophyte What are the differences in moss and ferns?
( correct answers )
Why are mosses and ferns found in moist habitats?
( correct answers ) they reproduce better
in moist habitats
Why is the fern considered to be more advanced than mosses? ( correct
answers ) they show true vascular tissue with both xylem and phloem
alteration of generations ( correct answers ) a life cycle in which
there is both a multicellular diploid form, the sporophyte, and a
multicellular haploid form, the gametophyte
gametophyte ( correct answers ) the stage in the life cycle of a plant
in which the plant produces gametes, or sex cells.
sporophyte ( correct answers ) the stage in the life cycle of a plant in
which the plant produces spores.
archegonium ( correct answers ) female reproductive structure in some
algae and plants
antheridium ( correct answers ) Male reproductive structure in some algae
and plants spore ( correct answers ) A reproductive cell with a hard,
protective coating
vascular tissue ( correct answers ) specialized tissue in plants that carries
water and nutrients
xylem ( correct answers ) vascular tissue that carries water upward from
the roots to every part of a plant
, phloem ( correct answers ) vascular tissue that transports material
made during photsynthesis
sorus ( correct answers ) cluster of sporangia on the underside of a
fern frond
sporangium ( correct answers ) spore capsule in which haploid spores are
produced by meiosis
In what kind of habitat would most spore bearing plants be found?
( correct answers ) moist environment
Do the gametophyte and sporophyte generations live independently in
mosses? ( correct answers )
no
Do the gametophyte and sporophyte generations live independently in
ferns?
( correct answers ) yes
What are the distinguishing characteristics of the animal kingdom?
( correct answers ) multicellular, most can move, cells have no cell wall, hunt
for their own food (heterotrophic or consumers), eukaryotic, and reproduce
sexually
coelom ( correct answers ) body cavity lined with mesoderm
psuedocoelom ( correct answers ) body cavity that is only partially
lined with mesoderm
What are the characteristics of phylum porifera? ( correct
answers ) no distinct tissues, no
symmetry, no coelomic plan, and not a deuterostome
What are the characteristics of phylum cnidaria? ( correct
answers ) have distinct tissues, radially
symmetrical, no coelomic plan, and not a deuterostome
what are the characteristics of phylum platyheliminthes? ( correct
answers ) have distinct tissues, bilaterally symmetrical, no coelomic
plan, and not a deuterostome
heterotrophic ( correct answers ) an organism that depends on outside
sources for obtaining food
radial symmetry ( correct answers ) symmetry around a central axis.
bilateral symmetry ( correct answers ) the property of
being divisible into symmetrical halves on either side of a unique plane.
acoelomate ( correct answers ) an animal that lacks a coelom, or body
cavity
