d. Gymnosperms are the simplest vascular plants.
|
|
Of all land plants, bryophytes alone have independent ______ and attached, dependent ______.
|
gameophytes; sporophytes
|
|
Whisk ferns, lycophytes, horsetails, and ferns are classified as _______ plants.
|
seedless vascular
|
|
What does not apply to 'gymnosperms' and 'angiosperms'?
|
single spore type
|
|
A seed is _______
|
a mature ovule
|
|
"naked seeds"
|
gymnosperms
|
|
spore-producing body
|
sporophyte
|
|
lycophyte
|
seedless vascular plant
|
|
ovary
|
usually a fruit at maturity
|
|
nonvascular land plant
|
bryophyte
|
|
gamete-producing body
|
gametophyte
|
|
help control water loss
|
stomata
|
|
protects, nourishes, disperses embryo sporophyte
|
angiosperm seed
|
|
vascular plants
|
internal tissues that conduct water and solutes through roots, stems, and leaves
|
|
bryophyte
|
Nonvascular land plant requiring free water to complete fertilization
|
|
xylem
|
distributes water and dissolved ions to all of the plant's living cells
|
|
Phloem
|
distributes dissolved sugars and other photosynthetic products
|
|
gametophytes
|
gamete-producing bodies. The diploid (2n) phase is the zygote, which forms when gametes fuse at fertilization.
|
|
sporophyte
|
a vegetative body that grows, by mitotic cell divisions, from a plant zygote and that produces spore-bearing structures
|
|
types of nonvascular plants
|
mosses, liverworts, and hornworts
|
|
existing seedless vascular plants
|
whisk ferns, lycophytes, horsetails, and ferns
|
|
how do they differ from bryophytes
|
the sporophyte does not remain attached to a gametophyte, it has true vascular tissues
|
|
dicots
|
flowering plant generally characterized by embryos with two cotyledons; net-veined leaves
|
|
monocots
|
flowring plant; floral parts generally in threes or multiples of... and often parallel-veined leaves
|
|
cuticle
|
waxy layer that keeps water in
|
|
stoma
|
carbon dioxide comes in thru a small space @ bottom of stem-between guard cells
|
|
Archaea
|
evolved over 3 billion years ago
|
|
psilopsida
|
whisk ferns; have branches, no leaves
|
|
lycopsida
|
club mosses; reach over 100' tall
|
|
sphenopsida
|
horsetails; scale shaped leaves w/silica reinforced stems
|
|
pteropsida
|
ferns; spores underneath leaves
