Pollinator-mediated selection is an evolutionary process occurring in flowering plants, in which the foraging behavior of pollinators differentially selects for certain floral traits. [1] Flowering plant are a diverse group of plants that produce seeds. Their seeds differ from those of gymnosperms in that they are enclosed within a fruit.
Pollination syndrome. Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection. [ 1][page needed][ 2][page needed] These ...
A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower. [ 1] This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains. Insects are the major pollinators of most plants, and insect pollinators include all families of bees and most ...
Pollination. Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds. [ 1] Pollinating agents can be animals such as insects, for example beetles or butterflies; birds, and bats; water; wind; and even plants themselves.
Dispersal vector. Dandelion seeds are adapted to wind dispersal. A dispersal vector is an agent of biological dispersal that moves a dispersal unit, or organism, away from its birth population to another location or population in which the individual will reproduce. [1] [2] These dispersal units can range from pollen to seeds to fungi to entire ...
Monocotyledon reproduction. A solitary bee pollinating an Allium monocot flower. The monocots (or monocotyledons) are one of the two major groups of flowering plants (or Angiosperms), the other being the dicots (or dicotyledons ). In order to reproduce they utilize various strategies such as employing forms of asexual reproduction, restricting ...
Pollinator exclusion experiments are experiments used by ecologists to determine the effectiveness of putative plant pollination vectors. Essentially, certain pollinators are prevented from visiting certain flowers, and observations are then made on which flowers develop seeds. If the exclusion of a certain class of visitor prevents or greatly ...
A flower, also known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae ). Flowers consist of a combination of vegetative organs – sepals that enclose and protect the developing flower. These petals attract pollinators, and reproductive organs that produce gametophytes, which in ...
