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
