STUDY
PLAY
sporophyte
seed producing vascular plants are _______ generation dominant
sporophyte
the spore-producing individual or phase in the life cycle of a plant having alternation of generations
gymnosperms
"naked seed" (seeds not covered by a fruit, seeds released from cones; nonflowering)
Phylum Cycadophyta
"the cycads"
100
How many species of cycads?
phylum cycadophyta
Flagellated sperm; frond-like leaves; dioecious (separate sexes); evergreen are all characteristics of _______ .
water
______ is not needed for reproduction in seed producing vascular plants even though 2 phyla contain sperm which are flagellated; sperm will travel by eggs by pollination contained in pollen
embryo
In seed producing vascular plants, _____ is packaged in seed used for dispersal of the species
Phylum Ginkgophyta
only one living species (ginkgo biloba)
Phylum Ginkgophyta
Flagellated sperm; broad-flat deciduous leaves, dioecious
dioecious
Referring to a plant species that has staminate and carpellate flowers on separate plants.
phylum coniferophyta
"the conifers" (pines, cedars, cypress, fir, spruce, etc.)
phylum coniferophyta
most are evergreen with needle-like leaves;
do not need water for reproduction;
wind carried pollen;
monoecious;
pollination vs. fertilization;

are all characteristics of _______ .
monoecious
having male and female reproductive organs in the same plant or animal
angiosperms
"enclosed seed" (have flowers; flowering plants produce seeds at the base of a flower resulting in a fruit; only one division)
phylum anthophyta
235,000 species; contains 2 classes: Monocotyledones and Eudicotyledones
class monocotyledones
"the monocots" 65,000 species (corn, lily, orchids, all grasses, etc.)
class monocotyledones
comprising seed plants that produce an embryo with a single cotyledon and parallel-veined leaves: includes grasses and lilies and palms and orchids
class eudicotyledones
"the eudicots" 170,000 species (oaks, hickories, violet, holly, dogwood, birches, poplars, elms, poinsettias, coleus, begonia, roses, geraniums, etc.)
monocot leaf
leaf veins form a parallel pattern
monocot seed
a seed that has one seed leaf and stored food outside the seed leaf; one cotyledon in seed
cotyledon
A "seed leaf" which develops as a part of the seed. It provides nutrients to the developing seedling and eventually becomes the first leaf of the plant.
monocot flower
flower parts in threes and multiples of three
eudicot seed
two cotyledons in seed
eudicot leaf
leaf veins form a net pattern
eudicot flower
flower parts in fours or fives and their multiples
conducting tissue
Seed producing vascular plants have ________, therefore have xylem and phloem and roots, stems, and leaves
plant fertilization
pollen lands on stigma. pollen grain releases tube cell. tube cell divides, formiing a pollen tube all the way to the ovary. generative cell releases two sperm. sperm travel down pollen tube for fertilization. tube enters microphyle.
seeds
ovules eventually develop into
pollination
the transfer of pollen from the male reproductive structures (the anthers) to the tip of a female reproductive structure (the pistil) of a flower in angiosperms or to the ovule in gymnosperms
