Pollination is the transfer of pollen grains from a flower’s anthers to the same or another flower’s stigmas. Pollens are moved from flower to flower by pollinators, such as butterflies, bees, beetles, moths, bats and birds. The wind also helps in pollination.Know More
Pollination leads to fertilization, which is the fusion of nuclei in the ovule with nuclei from the pollen grain. After successful fertilization, the flower starts to develop seeds. The production of seeds and fruits is contingent on pollination.
Some plants develop seeds through self-pollination, wherein the same plant possesses both pollen and pistil. Others need cross-pollination, wherein pollen and pistil come from different plants. Most plants need the help of pollinators to move pollen to the pistil.Learn more about Earth Science
Artificial pollination is the process of applying pollen to plants that would normally be applied by the insects that pollinate plants. Artificial pollination can be accomplished with the use of a brush to apply the pollen. This is a technique similar to the one biologist Mendel used while studying genetics and inheritance. There are several benefits to artificial pollination, including gaining greater control over the genetic population of the crops.Full Answer >
Wind pollination occurs when the pollen from flowers is transported by the wind. It is also known as anemophily, and it occurs every day to pollinate crops and trees.Full Answer >
Cross-pollination is the transport of pollen from a single plant to a different plant by insects or the wind. It merges the hereditary characteristics of two plants and creates more varied species.Full Answer >
Landslides often have devastating effects on humans. The wall of mud wipes out buildings, covers roads and changes the landscape. The economic cost of landslides in the United States ranges from $1 billion to $2 billion annually. NBC News reports a death toll of 41 individuals with two missing from the March 22, 2014, landslide in Oso, Washington.Full Answer >
