Hi guys, I'm Claire, host of this YouTube series and author of the website brilliantbotany.com.
Today I'm going to be talking about some really cool research into mosses, fertilization and
volatile compounds.. You're probably familiar with plant-pollinator relationships.
Pollinators, like bees, butterflies, bats or even lemurs, visit the flowers on angiosperms--flowering
plants--and transfer pollen between them.. This allows that pollen to fertilize egg cells and further reproduction.
Flowers often offer incentives, like nectar, for pollinators and evolved things like bright
colors to attract their attention.. Hummingbirds, for example, are drawn to bright red flowers, like torch lilies, and bees follow
ultraviolet nectar guides when visiting flowers.. Mosses, however, are not angiosperms, so they don't have flowers.
And if you'd like a quick intro to the moss life cycle, you can check out this video that
I made a few weeks ago.. It has long been assumed that mosses are fertilized only with the help of water.
When it rains, the moss sperm cells swim through the water using their two flagellum to get
to egg cells and fertilize them.. Recent research has shown, however, that springtails and mites aid in fertilization of mosses,
much like angiosperm pollinators.. A study by Todd Rosenstiel and his team, published in Nature, has even shown that mosses produce
