Plants that can pollinate themselves and produce viable offspring are called self-fertile. Plants that cannot fertilize themselves are called self-sterile, a condition which mandates cross-pollination for the production of offspring. [47] Cleistogamy: is self-pollination that occurs before the flower opens. The pollen is released from the ...
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. These ...
Water-pollinated plants are aquatic and pollen is released into the water. Water currents therefore act as a pollen vector in a similar way to wind currents. Their flowers tend to be small and inconspicuous with many pollen grains and large, feathery stigmas to catch the pollen.
Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...
Such constraints are absent from wind-pollinated plants, and the contrasting biophysical requirements for pollen dispersal and pollen capture have led to striking cases of sexual dimorphism in plant architecture and flower production in some species. [4] Below are some specific examples of sexual dimorphisms in flowering plants.
Pollinators will learn and discriminate against floral stages from these signals benefiting both parties by allowing insects to be guided to flowers that are rewarding, while the flowers receive pollination. [5] [7] It has been shown that the size of the plant's floral display is important in relation to plant-pollinator interactions. Larger ...
A pollinator garden is a group of plants grown together with the intention of attracting wild pollinators. Pollination is the reproductive process that enables plants to produce seeds. [5] When pollen from the male part of one flower is moved to the female part of another flower of the same species, fertilization occurs.
A flower’s size, shape, color, scent, and pattern all play a role in signaling with the senses of pollinators. [2] Plants that rely on animal pollinators are most likely to use the UV coloration strategy compared to other plants to increase the odds of them being pollinated. [7]
