Some plants have male and female parts on the same flower and can self-pollinate, while other plants produce male and female parts on separate plants. In any event, pollination requires the movement of pollen from the stamen to the pistil so the steps of sexual plant reproduction can continue...

Plant - Reproduction, Life Cycles, Pollination: The life history of land plants involves two alternating multicellular phases, or generations, that are morphologically dissimilar. Meiosis and syngamy (fertilization) are the critical events that separate
facilitation via pollinator sharing might be the rule rather than the exception in harsh environments. Moreover, plant diversity could be playing a key role in fostering pollinator-mediated facilitation. Yet, the facilitative effect of plant diversity on pollination remains poorly...
Insect Pollination and the Angiosperm Radiation The role of plant–pollinator interactions in reproductive isolation has also led to the much grander hypothesis that insect pollination was a “key innovation” leading to the co-radiation of flowering plants (angiosperms) and anthophilous insects, which...
On pollination The astute reader may have noticed that in the above outline of the four-sex model as applied to angiosperms there was no mention made of pollination. That was because pollination, according to the definitions presented earlier, is neither a sexual nor a reproductive process: Poll...
Understanding the different parts of a flower is key to appreciating their role in plant life. Stamen: The male reproductive organ, comprising the anther, which produces pollen. Petal: The colourful and often fragrant part of the flower, attracting pollinators. Ovary: The base of the pisti...
摘要: PURPOSE: To selectively propagate only one desired female or male clone individual among female and male green plant individuals by propagating only one female or male individual of a dioicous plant by using the tissue culture technique....
(Figure 1). Scientific collections have many specific uses [6]. Herbaria, for example, can be used to trackphenology, gauge resulting impacts on pollination ecology, or examine how levels and/or types of herbivory have changed over decades or centuries; they are also essential for modeling how...
Mutualisms involving animal-mediated pollination and seed dispersal, and symbioses between plant roots and microbiota often facilitate invasions. The spread of many alien plants, particularly woody ones, depends on pollinator mutualisms. Most alien plants are well served by generalist pollinators (insects...
