The gymnosperms (check all that apply):
have woody tissue from secondary growth.
have flowers.
have seeds
have cones
have fruit
Another name for a seed is a:
microgametophyte
integumented megasporangium
fruit
hepatomicrocephalomeric spore
The megagametophyte
is a pollen grain that contains the egg cell.
a female gametophyte that contains the egg cell.
is a female gametophyte that contains the pollen grain.
is a pollen grain that is the male gametophyte.
The microgametophyte
is a pollen grain that contains the egg cell.
a female gametophyte that contains the egg cell.
is a female gametophyte that contains the pollen grain.
is a pollen grain that is the male gametophyte.
Gymnosperms are pollinated by:
bees, birds, bats, and moths.
bees only.
the wind.
Hold up, Smith. Gymnosperms do not have pollen.
Gymnosperms make lots of pollen compared to flowering plants because:
It is up to wind and chance to pollinate gymnosperms.
It is not energetically costly to produce lots of pollen.
They like making pollen for bees.
Pollen help them grow bigger and outcompete other plants around them.
Gymnosperms make male and female cones.
True
False
Why do conifers place the male cones below the female cones?
To transport the pollen shorter distances.
To prevent the male cones from fertilizing the female cones on the same tree.
Making the male cones is more energetically costly, so they do not have to move nutrients as high on the plant.
To attract bees.
To prevent self-fertilization, some conifers will (check all possible answers):
Make male cones lower than female cones on a tree.
Make male cones first, then female cones once the male cones are finished.
Only have male cones on one tree, and female cones on another tree.
Have resin ducts.
According to this phylogeny (check all that apply):
Cycads and Ginkgo are sister taxa.
Gnetales and Conifers are sister taxa.
Gymnosperms and Angiosperms are sister taxa.
Pteridophytes and Seed Plants are sister taxa.
Lycopods and Pteridophytes are sister taxa.

Which is an example of a conifer?
Cedar tree
Pine tree
Spruce tree
Fir tree
All of these are conifers
The female cone on this plant becomes smelly and undesirable. That is why people selling trees will typically only sell male trees.
Though not a fern at all, this is sometimes called a 'tree fern' and in the Cycad group.
These make fancy, expensive indoor plants:

endosperm
female gametophyte
the (a) develops into the pollen grain

True
False
