Fern Life Cycle
Fern Life Cycle
The dominate life stage of ferns is the sporophyte stage. This means that the fern structures that you see are diploid and produce spores. Fern spores are produced in sporangia which are located in small clusters on the underside of fern pinnae. These small clusters of sporangia are called sori. Once the haploid spores are released, the spores grow into an indepandent fern gametophyte called a prothallium. The antheridia on the prothallium produce flagellated sperm which can swim to the archegonia on a thin layer of moisture. At the archegonia the sperm can fertilize the egg. Once fertilized the zygote grows into a new diploid fern. Take a look at this cool picture of the fern life cycle here.
In this photo you can see the small orange sori on the underside of this fern’s pinnae.

Fairlytale Scandinavian Green Roofs
Scandinavians are serious about their green roofs. They’ve had them for a while now and it doesn’t look like they’re going anywhere. They even have a competition every year to determine the best green roof project in Scandinavia by the Scandinavian Green Roof Association! But there is a reason why Scandinavians like these green roofs so much… They are not only a beautiful feature for a house, but they also offer numerous social, environmental and financial benefits. They absorb rainwater, reduce winter heating costs, reduce summer air-conditioning costs, provide insulation, and are long lasting - just to name a few.
