✨NOTES FOR TODAY #SCIENCE ✨
Orchids
Orchidaceae
orchid
Thousands of species
There are more than 25,000 documented orchid species throughout the world, with hundreds more being discovered each year. This means the number of orchid species on the planet is four times the number of birds and four times the number of mammals!
Orchids can be found throughout the world, and can survive in different kind of habitats. Most species live in tropical rainforests, but they can also be found close to the Arctic Circle.
Seeds like dust
There can be up to three million seeds in a single orchid seedpod. You’ll never see them though, they are the size of a speck of dust and are only visible under a microscope. Part of the reason for their small size is that they lack an endosperm to provide the nutrients needed to germinate. This means they can only germinate and grow when they come into contact with the right kind of fungus.
