Cell division and Reproduction Quiz 5 Review
A sporangium that produces microspores.
microsporangium
The tube that grows from the pollen grain to penetrate the ovule for fertilization.
pollen tube
Transfer of pollen from male to female cones in gymnosperms, or from anther to stigma in flowering plants.
pollination
The pollen produced by a gymnosperm is formed in the female cone.
false
A female cone in gymnosperms. It produces seeds.
ovulate or seed cone
A flower containing a pistil, stamen, calyx, and corolla.
complete flower
The female part of the flower.
pistil
A ______ is the sticky end of a pistil where pollen is caught.
stigma
Some flowers are able to pollinate themselves.
true
Some flowers have a complete set of male and female parts for fertilization.
true
The petals of a flower have no reproductive function.
false
The sticky, terminal end of the pistil where pollen is caught in pollination.
stigma
A flower that lacks one or more of the following parts: pistil, stamen, calyx, or corolla.
incomplete flower
The pine cone seed is the:
container for the fertilized egg
A flower having both male and female parts.
perfect flower
Life cycles found in vascular plants are variations of the ______ life cycle.
Sporic
A life cycle in which the sporophyte is more than the zygote, and the gametophyte is more than a gamete. The gametophyte and the sporophyte alternate with one another through time.
sporic life cycle
The green leafy plants recognized as ferns are from the ______ generation of the plant.
sporophyte
The gymnosperm tree or shrub comprises the _____ generation of the plant.
sporophyte
An increasingly intricate relationship exists between the gametophyte and sporophyte generations in vascular plants. As vascular plants live longer, they increase in size and complexity and the _______ generation becomes dominant, while the ________ generation becomes smaller and of shorter duration.
sporophyte gametophyte
The collective term for the sepals is .
calyx
Vascular plants have a _______ alternation of generations.
heteromorphic
The fully developed ovule becomes a
seed
A group of sporangia in ferns.
sorus
A spore-producing cell or structure in protists and plants.
sporangium
How does the egg of a flower become fertilized?
when the pollen tube grows into the ovule
A spore produced by meiosis.
meiospore
The gametophyte generation of a fern is called the
prothalilum
The idea that the sporophyte generation and the gametophyte generations follow one another in alternating fashion.
alternation of generations
A row of specialized cells around the sporangium of most ferns. It plays a role in opening the sporangium and releasing spores.
annulus
Pollination of a flower requires that the pollen produced in the _____ be deposited on the ________ .
anther stigma
The organ that produces the egg cell in the life cycle of the pine is called the
archegonium
About one year is required in the gymnosperm:
between pollination and fertilization
A stalk which supports the anther. It is part of the stamen.
filament
The collective term for the sepals.
calyx
The collective term for the petals of a flower.
corolla
A flower's sepal is part of the corolla.
false
A flower that has female parts only. It has pistils, but no stamens.
female flower
The ripened ovaries of a flower produce: .
fruit
A haploid generation. Produces gametes.
gametophyte generation
Alternation of generations in which the sporophyte and gametophyte generations have a different size, shape, or appearance.
heteromorphic alternation of generations
Producing spores that are different in size and shape.
heterosporous
Producing spores that are all the same in size and shape.
homosporous
In considering the difference between the male and female pine cones, the _______ is small, short-lived, and nearly unnoticeable on the tree. The _______ is the one we recognize as the pine cone.

A flower that has male parts only. It has stamens but no pistils.
male flower
Spores produced by the small male cone of a pine tree are produced by .
meiosis
A structure within the ovary of a flower that contains the female gametophyte. It develops into a seed after fertilization.
ovule
Pine cone seeds are produced in the _____ of the _____ cone.
ovule female
The ____ flower has both _____ stamens and _______ pistil parts.
