final project 2

" Researches prove how plants transport sugar "
summary :
there are some researchers prove how plants transports sugar. And then the result of their research, that the sucrose a from of suagars into leaves as a product of photosynthesis, it spread of into the phloem with other nutrients. After Turgeon and McCaskill research they get something from their research if in normal plants, the sucrose made from water and carbon dioxide during photosynthesis collect in the leaves, the photosynthesis will be slows down and the plant can not get more carbon dioxide from the air. And then sugars move out of the leaves and carbon intake increase.
main idea : Processing of transporting sugars

"Greenland and antartic Ice sheet melting, Rate unknown"
summary :
Ice sheet are melting in the greenland and antartica. The ice sheet will be melt if the temperatures became warm enough. Previously many scientist suggested that this would offset increasing melting. Large lakes of water on the ice in greenland pose a problem. Observer have seen lakes on the greenland ice sheet drain at the speed of niagara falls. Water beneath the ice allows the ice to move more rapidly. And then rocks and cliffs on the sides of fiords or inlets slow the seaward movement of the ice shelves. If these shelves break up and melt, the ice streams behind them move more rapidly. So, the main factor for the ice sheet melting caused by general global warming.
main idea : the effect of global warming in greenland and antartica.
