The green algae (singular: green alga) are the large group of algae from which the embryophytes (higher plants) emerged.[1] As such, they form a paraphyletic group, although the group including both green algae and embryophytes is monophyletic (and often just known as kingdom Plantae).
The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic seaweeds. In the Charales, the closest relatives of higher plants, full differentiation of tissues occurs. There are about 8,000 species of green algae.[2] Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. Cellular structure[edit] All green algae have mitochondria with flat cristae. Origins[edit] Evolution and classification[edit] A growth of the green seaweed, Enteromorpha on rock substratum at the ocean shore.
Chemistry[edit] Craig's Picture of the Day. WarmDirt Last winter we tried heating our green house without success and large electric bills.
This year we tried Warm Dirt. I made a wood box about coffin size. Melanie and I lined the bottom with Electric Heat Cable, poured in 4 inches of sand, then placed her clay pots on the sand. Keep the roots warm (above 40F) and you're good to grow. Here I'm putting the plants to bed. I first started with an simple AC timer that switched the heater tape on and off, but we didn't really know any temperatures. The timer worked fine for a while, but then obsession took over, I needed more data, more control, more power.
Here's the WarmDirt README file. How to build My 50 Dollar Greenhouse & The Door Garden - StumbleUpon. First off – you really can build this thing very cheaply, but to do so you have to recycle, freecycle, and scrounge.

Laptop computers are wireless. Why can’t an entire neighborhood be wireless? No power lines, no telephone lines, no sewer lines? While not everyone wants to embrace the challenges that come with living independent of any utility connections, a number of communities across the globe are experimenting with living off the grid as part of being a sustainable, self-sufficient village. An article in USA Today stated that according to Richard Perez, publisher of Home Power magazine, about 180,000 American households were living off the grid. British journalist and documentary filmmaker Nick Rosen interviewed some of them for his book, "Off the Grid: Inside the Movement for More Space, Less Government, and True Independence in Modern America.
" Some off-the-grid communities are little more than subdivisions beyond the reach of any power company, where homeowners fend for themselves. Here’s a look at some of them: Three Rivers Recreation Area Greater World Community. Earthbag Construction.
