Flashcards: Botany

In botany, a bud is an undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of a stem.

Plant ecology is a subdiscipline of ecology which studies the distribution and abundance of plants, the effects of environmental factors upon the abundance of plants, and the interactions among and between plants and other organisms.

A vascular bundle is a part of the transport system in vascular plants.

Monoicous plants are those species that bear both sperm and eggs on the same gametophyte.

Photoperiodism is the physiological reaction of organisms to the length of day or night.

Altitudinal zonation in mountainous regions describes the natural layering of ecosystems that occurs at distinct altitudes due to varying environmental conditions.

In botany, apomixis was defined by Hans Winkler as replacement of the normal sexual reproduction by asexual reproduction, without fertilization.

In astronomy, a light curve is a graph of light intensity of a celestial object or region, as a function of time.

The lotus effect refers to self-cleaning properties that are a result of ultrahydrophobicity as exhibited by the leaves of Nelumbo or "lotus flower".

Allelopathy is a biological phenomenon by which an organism produces one or more biochemicals that influence the germination, growth, survival, and reproduction of other organisms.

In evolutionary ecology, an ecotype, sometimes called ecospecies, describes a genetically distinct geographic variety, population or race within a species, which is adapted to specific environmental conditions.

The history of botany examines the human effort to understand life on Earth by tracing the historical development of the discipline of botany—that part of natural science dealing with organisms traditionally treated as plants.

Linnaeus' flower clock was a garden plan hypothesized by Carolus Linnaeus that would take advantage of several plants that open or close their flowers at particular times of the day to accurately indicate the time.

Myco-heterotrophy (Greek: μυκός mykós, "fungus", ἕτερος heteros = "another", "different" and τροφή trophe = "nutrition") is a symbiotic relationship between certain kinds of plants and fungi, in which the plant gets all or part of its food from parasitism upon fungi rather than from photosynthesis.

Tropical vegetation is any vegetation in tropical latitudes.

A xylotheque (from the Greek xylon for "wood" and "theque" meaning "repository") is a wood collection.

Plant breeding started with sedentary agriculture, particularly the domestication of the first agricultural plants, a practice which is estimated to date back 9,000 to 11,000 years.

Plant identification is the process of matching a specimen plant to a known taxon.
