Q

Gametic Isolation

A

Gametic transfer takes place, but the gametes fail to unite with each other. This can occur because the male and female gametes fail to attract, because they are unable to fuse, or because the male gametes are inviable in the female reproductive tract of another species. In plants, the pollen of one species usually cannot generate a pollen tube to fertilize the egg cells of another species.

A

An organism that is able to use photoautotrophy as well as phagotrophy or osmotrophy to obtain organic nutrients.

146
Q

Cysts

A

A unicellular or multicellular structure that often has a thick, protective wall and can remain dormant through periods of unfavorable climate or low food availability.

147
Q

Streptophytes

A

Land pants (embryophytes) and their close relatives among the green algae.

148
Q

Streptophyte Algae

A

The green algae that are closely related to land plants (embryophytes).

149
Q

Alternation of Generations

A

The phenomenon that occurs in plants and some protists in which the life cycle alternates between multicellular diploid organisms, called sporophytes, and multicellular haploid organisms, called gametophytes.

150
Q

Sporophyte

A

The diploid generation of plants or multicellular protists that have a sporic life cycle; this generation produces haploid spores by the process of meiosis.

151
Q

Gametophyte

A

In plants and many multicellular protists, the haploid stage that produces gametes by mitosis.

152
Q

Spores

A

A haploid, typically single-celled reproductive structure of fungi and plants. A spore is able to grow into a new fungal mycelium or plant gametophyte in a suitable location.

153
Q

Vascular plants

A

A broad category of plants distinguished by internal water and nutrient-conducting (vascular) tissues that also provide structural support.

154
Q

Bryophytes

A

Liverworts, mosses, and hornworts, the modern nonvascular land plants.

155
Q

Tracheid

A

A type of dead, lignified plant cell in xylem that conducts water, along with dissolved minerals and hormones; also provides structural support.

156
Q

Spermatophytes

A

All of the living and extinct phyla of seed-producing plants.

157
Q

Gymnosperm

A

A plant that produces seeds that are exposed rather than seeds enclosed in fruits.

158
Q

Gametangia

A

Specialized structures produced by some fungi and many land plants in which developing gametes are protected by a jacket of tissue.

159
Q

Archegonia

A

Flask-shaped gametangia that each enclose a single egg cell in plants.

160
Q

Antheridia

A

Spherical or elongate gametangia that produce sperm in plants.

161
Q

Matrotrophy

A

In plants, the phenomenon in which zygotes remain enclosed within gametophyte tissues, where they are sheltered and fed.

162
Q

Progymnosperms

A

An extinct group of plants having wood but not seeds, which evolved before the gymnosperms.

163
Q

Eustele

A

In plants, a ring of vascular tissue arranged around a central pith of nonvascular tissue; typical of progymnosperms, gymnosperms, and angiosperms.

164
Q

Coevolution

A

The process by which two or more species of organisms influence each other’s evolutionary pathway.

165
Q

Pollination Syndromes

A

The pattern of coevolved traits between particular types of flowers and their specific pollinators.

166
Q

Domestication

A

A process that involves artificial selection of plants or animals for traits desirable to humans.

167
Q

Shattering

A

The process by which ears of wild grain crops break apart and disperse seeds.
