Terms in this set (41)
Full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions
genet (clonal colony)
a group of genetically identical individuals, such as plants, fungi, or bacteria, that have grown in a given location, all originating vegetatively, not sexually, from a single ancestor
An individual member of a plant clone
a species with a broad niche that can tolerate a wide range of conditions and can use a variety of resources
a species with a narrow niche
The full potential range of the physical, chemical, and biological factors a species can use if there is no competition from other species
when a species occupies a smaller niche than it would in the absence of competition
a flower that has the male and female parts
The placement of pollen onto the stigma of a carpel by wind or animal carriers, a prerequisite to fertilization.
when the pollen nucleus joins the egg
Organisms, such as mammals, insects, and birds carry or move the pollen grains from anther to stigma
A relationship between two species in which both species benefit
organism that requires a constant supply of oxygen in order to live
organism that can survive with or without oxygen
a collective term for a group of flowers attached to a common axis in a specific arrangement
Conversion of light energy from the sun into chemical energy
Process by which unrelated organisms independently evolve similarities when adapting to similar environments
An individual organism that changes sex from female to male or male to female at some time in its life cycle.
pollination by a nonliving agent such as wind, about 20% of pollination
false symbiotic relationship, a relationship with deception
behaviors similar to copulation that serve a reproductive function for one or both participants but do not involve actual sexual union between the individuals.
the number of offspring an individual is likely to have
r/K selection theory
The two evolutionary "strategies" are termed r-selection, for those species that produce many "cheap" offspring and live in unstable environments and K-selection for those species that produce few "expensive" offspring and live in stable environments.
single reproductive episode before death
repeated reproduction before death
reproduce early; short-lived; many small unprotected offspring or semelparous; opportunists
reproduce late in life; long lived; few offspring; care for offspring
a plant that grows vegetatively for more than one year but only flowers once and then dies
a plant that flowers and fruits more than once
A flowering plant that completes its life cycle in one growing season.
a plant that lives for many years
Plantago lanceolata (English Plantain)
case study in class of a plant that can reproduce asexually with cloning, or sexually with pollen- used as an indicator in agriculture of pollen dispersal, and an indicator of compacted soil, also example of varying concentrations of lead tolerance- ecotype
Achillea lanulosa (Western Yarrow)
case study in class of a plant with many inflorescences, a generalist- also example of a plant that has varying ecotypes- does not cause allergies like ragwort
Chiloglottis reflexa (Chiloglottis orchid)
case study in class of false mutualism: pseudocopulation- the plant tricks male wasps into pollinating it by mimicking the appearance of a female wasp
Trifolium repens (White Clover)
case study in class of clonal growth
case study in class of an example of an agamospecies (clonal species) that goes through microevolutions
the timing of seasonal events
A species of organisms in which sexual reproduction does not occur, collection of clones.
Change in genetic makeup of a population from generation to generation.
case study in class of convergent evolution
