|
What is the difference from the gametophytes of seedless vascular plants and seed plants
|
you are able to see the gametophytes of seedless vascular plants with the naked eye you need a microscope for the seed plants
|
|
|
What does small gametophytes help accomplish
|
it allows plants to create spores inside the sporophyte which has a protective layer
|
|
|
What are integuments
|
they envalope and protect the megasporangium
|
|
|
Which has two integuments gymnosperms or angiosperms
|
angiosperms
|
|
|
What is a megasporangium,a megaspore, and an integument called
|
an ovule
|
|
|
what is something that contains the male gametophyte of seed plants
|
a pollin grain
|
|
|
What is pollination
|
it is the transfer of pollen to the part of the plant that contains ovules
|
|
|
how many sperm are discharged into the ovule
|
two
|
|
|
What is unique about conifers
|
they are cone bearing gymnosperms
|
|
|
What is the name of a transitional species of seedless vascular plants
|
progymnosperms
|
|
|
What were the key reproductive adaptations that lead to the evolution of seed plants
|
Increasing dominance of the sporophyte generation, the seed, and the evolution of pollen
|
|
|
What are the key adaptations of angiosperms and what phylum do angiosperms fall into
|
flowers and fruits
anthrophyta |
|
|
what is and angiosperm structure specalized for sexual reproduction
|
a flower
|
|
|
What makes up a flower
|
sepals,petals,stamens, and carples
|
|
|
What do the sepals do
|
they enclose the flower before it opens
|
|
|
what are normally brightly colored and aid in the attracting of pollinators
|
petals
|
|
|
What gives rise to the male reproductive gamete in angiosperms
|
stamen
|
|
|
What does a stamen consist of and what do the parts do
|
Filament which is a stalk
Anther a sac where pollin is produced |
|
|
What gives rise to the female reproductive gametein angiosperms
|
carples
|
|
|
What does the carple consist of and what do the parts do
|
stigma recieves pollin
style leads to the ovary ovary the base of the carple that if fertalized becomes the seed |
|
|
The whole of the floral organs are attached to a
|
receptacle
|
|
|
What is a pistil
|
either a single carple or a group of fused carples
|
|
|
What is the mature ovary
|
the fruit
|
|
|
When the fruit is pollinated and starts to grow what is it called
|
a pericarp
|
|
|
can fruits be dry
|
yes
|
|
|
What is located in the pollin grain
|
two haploid cells a generator cell the divides into two sperm and a tube cell
|
|
|
What is the female ovary in angiosperms called q
|
the embryo sac
|
|
|
What is it when plants try to avoid pollinating themselves they are facilitating
|
cross pollination
|
|
|
What is the micropyle
|
it is the integuments of the ovule
|
|
|
What plant species uses double fertalization
|
angiosperms
|
|
|
What are the embryonic leaves
|
cotyledons
|
|
|
What is the endosperm
|
it is a tissue rich in starch and other food reserves
|
|
|
What is the function of double fertalization
|
it allows for the formation of the endosperm and the embryo at the same time
|
|
|
what has one cotylton a monocot or dicot
|
monocot
|
|
|
What has the clade dicot been broken into
|
eudicot basal angiosperms and magnoliids
|
