A rufous hummingbird (Selasphorus rufus) is attracted to brightly colored flowers and assists the pollination of the plant.Zoophily, or zoogamy, is a form of pollination whereby pollen is transferred by animals, usually by invertebrates but in some cases vertebrates, [1] particularly birds and bats, but also by other animals.
Self-pollination is promoted by homogamy. Homogamy is when the anthers and the stigma of a flower are being matured at the same time. [5] The action of self-pollination guides the plant to homozygosity, causing a specific gene to be received from each of the parents leading to the possession of two exact formats of that gene. [6]
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 ...
Cross-pollination, also called allogamy, occurs when pollen is delivered from the stamen of one flower to the stigma of a flower on another plant of the same species. [8] Plants adapted for cross-pollination have several mechanisms to prevent self-pollination; the reproductive organs may be arranged in such a way that self-fertilisation is ...
Anthecology, or pollination biology, is the study of pollination as well as the relationships between flowers and their pollinators. [1]: 8 Floral biology is a bigger field that includes these studies. Most flowering plants, or angiosperms, are pollinated by animals, and especially by insects. [2]
Interspecific sexual mimicry can also occur in some plant species. The most common example of this is known as sexually deceptive pollination and is found among some orchids. [23] The orchid mimics its pollinator's females, usually hymenopterans such as wasps and bees, attracting the males to the flower. Orchid flowers mimic the sex pheromones ...
Zoophily, or animal pollination, is a method of pollination which utilizes animals as pollen vectors. In order for pollen to affix to animal bodies, a tryphine coating is usually present in zoophilous pollen to achieve an adhesive pollen grain. [1] Visual attractants of monocot flowers mainly come from the coloration of tepals.
Some plants are pollinated by wind or water, but the majority are pollinated by animals called pollinators. [7] By producing nectar to attract pollinators, plants encourage to move from flower to flower, carrying pollen with them and resulting in pollination. [6] Close to 90% of all flowering plants are pollinated by animals. [8]
