Gametophye
|
The gamete-producing phase in a plant characterized by alternation of generations
|
|
sporophyte
|
the form of a plant in the alternation of generations that produces asexual spores.
|
|
capsule
|
the sporangium of various spore-producing organisms, as ferns, mosses, algae, and fungi.
|
|
sporangium
|
the case or sac in which spores are produced.
|
|
seta
|
A stiff hair, bristle, or bristlelike process or part on an organism.
|
|
peristomal teeth
|
the one or two circles of small, pointed, toothlike appendages around the orifice of a capsule or urn of mosses, appearing when the lid is removed.
|
|
frond
|
The leaf of a fern.
|
|
rhizome
|
rootlike subterranean stem, commonly horizontal in position, that usually produces roots below and sends up shoots progressively from the upper surface.
|
|
indusium
|
An enclosing membrane, as that covering the sorus of a fern.
|
|
sorus
|
one of the clusters of sporangia on the back of the fronds of ferns.
|
|
annulus
|
a growth ring, as on the cross section of a tree trunk, that can be used to estimate age
|
|
tapetum
|
a layer of cells often investing the archespore in a developing sporangium and absorbed as the spores mature.
|
|
antheridium
|
A sperm-producing organ occurring in seedless plants, fungi, and algae.
|
|
archegonium
|
the female reproductive organ in ferns, mosses, etc.
|
|
What forms on the opposite side of the sporangium
|
lips cells
|
|
sporopollenin
|
an inert, tough polymer forming the resistant outer coat of a pollen grain or spore.
|
|
byrophyte
|
any of the Bryophyta, a phylum of nonvascular plants comprising the true mosses and liverworts.
|
|
lycophyte
|
Any of various seedless vascular plants belonging to the phylum Lycophyta and characterized by microphylls (primitive leaves found in ancient plants).
|
|
Ferns reproduce by
|
spores
|
|
The outer layer of a sporangium contains a protective layer called
|
jacket cells
|
|
When a spore lands on a moist surface it will germinate and form a
|
hermaphroditic gametophyte
|
|
a young gametophyte is also called a
|
prothallus
|
|
what shape is a gametophyte
|
a heart
|
|
Where are antheridia located on the gametophyte
|
tip of heart
|
|
some bisexual gametophyte might be surrounded by only male gametophytes which increases chance of
|
cross fertalization
|
|
Zygotes divides and forms the
|
embro sporified plant
|
|
the fern life cycle has two plants
|
the sporophyte and gametophyte
|
|
are gametes produced my meiosis
|
no, spores are
|
|
What is the general term for Byophytes? Is it the same as Bryophyta?
|
Bryophytes are all embryophytes ('land plants') that are non-vascular: Bryophyta is one of the 3 groups.
|
|
What is the ressurection plant?
|
Lycophyta
|
|
What phylum do ferns belong to?
|
Pteridophyta
|
|
What phylums do mosses belong to?
|
bryophyta
|
|
Why do mosses live in damp areas? do they have waxy cuticles?
|
They have "swimming" sperm that can only reproduce through water. Yes they do
|
|
Do mosses have vascular tissues? what is a vascular tissue?
|
No. Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally
