Which of the following is NOT true?
a. Monocots and dicots are two classes of angiosperms.
b. Bryophytes are nonvascular plants
c. Lycophytes and angiosperms are both vascular plants.
d. Gymnosperms are the simplest vascular plants.
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
