Biology: Reproduction
gametangium (pl. gametangia)
an organ of lower plants, some protists, and some fungi that produces gametes
Which of the following conduct the most pollination for angiosperms?
bees
An onion or a daffodil reproduces by means of an underground structure called a ________.
bulb
pistil
the female sex organ of the plant
stamen
the male organ of plants; a ring of pollen-producing appendages of a flower
anther
the part of the stamen of a flower that bears the pollen
ovary
the round bottom part of the pistil where seeds grow
This is a specialized underground stem used in asexual reproduction and food storage.
Corm
________ is the transfer of pollen from male to female plant parts.
Pollination
A _________ is a horizontal stem at or just beneath the surface of the ground which can give rise to roots or stems.
Rhizome
style
a column-like part of the pistil that supports the stigma of a flower
tuber
a fleshy, enlarged stem of a rhizome or stolon; has buds and can grow new plants
rhizome
a horizontal stem at or just beneath the surface of the ground which can give rise to aerial stems, roots, or more rhizome tissue; a principal means of asexual reproduction in many plants
bulb
a plant structure with enlarged leaf bases and stored food surrounding a central bit of fleshy stem tissue
corm
a short, solid, enlarged underground stem used for food storage and asexual reproduction
archegonium (pl. archegonia)
an organ in lower vascular plants, gymnosperms, mosses, and liverworts that produces an egg cell
Plants that produce seeds within a cone are called ________.
gymnosperms
gametophyte
plant that produces gametes
sporophyte
plant that produces spores by meiosis
A ________ is a stem growing from a plant that produces roots, stems, and leaves at various points. A common example is the strawberry plant.
rhizome
The ripened ovaries of a flower contain the _________.
seeds
Select all that apply. The pistil of a flower consists of the ________.
style ovary stigma
adventitious
the appearance of buds or roots from tissue that is not bud or root tissue; when roots appear from stem or leaf tissue and buds appear in root tissue
antheridium (pl. antheridia)
an organ in simpler plants that produces sperm cells
stolon
a stem that grows out from a plant, periodically producing new stems and leaves on one side and roots on the other; a means of asexual reproduction
Plants that fertilize with spores are called ________.
sporophytes
Perfect flowers have both male and female parts. The male part is called the _______ and the female part is called the _______.
stamen, pistil
The portion of the vascular plant that has the majority of the methods of asexual reproduction occurring in it is the ________.
stem
stigma
the sticky, terminal end of the pistil where pollen is caught in pollination
pollination
transfer of pollen from male to female cones in gymnosperms, or from anther to stigma in flowering plants
A fleshy, enlarged end of a rhizome or stolon is called a ________.
tuber
