Biology by Amanda Sheffield https://padlet.com/asheffie/rrwxql9hrk52 Role of Plants en-us 2017-06-05 17:19:43 UTC 2025-11-06 09:04:32 UTC hello@padlet.com Unit 1 asheffie https://padlet.com/asheffie/rrwxql9hrk52/wish/175300133 The bright green and multiple plants that are visible represent life. Our plant's ecological systems purify air and water, cycle nutrients, regulate climate, pollinate plants and receive and recycle our waste. These plants are the backbone for life. Plants are an essential resource for human life. I love the purity that this picture represents. The picture looks refreshing and clean.  ]]> 2017-06-06 00:11:57 UTC https://padlet.com/asheffie/rrwxql9hrk52/wish/175300133 Unit 2 asheffie https://padlet.com/asheffie/rrwxql9hrk52/wish/176168218 Photosynthesis is important because it provides two main things: food and oxygen. Among the most important factors that affect photosynthesis are temperature, light intensity, and the availability of water. Photosynthesis captures energy for life on Earth. ]]> 2017-06-12 22:56:53 UTC https://padlet.com/asheffie/rrwxql9hrk52/wish/176168218 Unit 3 asheffie https://padlet.com/asheffie/rrwxql9hrk52/wish/177034917 The Georgia Native Plant Society is a nonprofit organization dedicated to promoting the stewardship and conservation of Georgia's native plants and their habitats. Plants from across Georgia can be searched on this website.  All native Georgia plants are listed on this site. Each plant has its scientific name, plant type, and a description of where the plant grows.  Bryophytes, pteridophytes, gymnosperms, and angiosperms can all be viewed and researched on the Georgia Native Plant Society website. ]]> 2017-06-20 22:42:51 UTC https://padlet.com/asheffie/rrwxql9hrk52/wish/177034917 Unit 4 asheffie https://padlet.com/asheffie/rrwxql9hrk52/wish/177572548 I believe the tundra is the most at risk biomes. It is the coldest and the largest, covering one fifth of the land on earth. The tundra is a very fragile biome. As the area gets warmer, the tundra is beginning to shrink. The biome is at risk because it has such a fragile ecosystem. Many animals will face extinction because of global warming.]]> 2017-06-27 16:36:40 UTC https://padlet.com/asheffie/rrwxql9hrk52/wish/177572548 Unit 5 asheffie https://padlet.com/asheffie/rrwxql9hrk52/wish/177860973 The Neolithic time period was from 10,000-8,800BC. This time frame is known as the period of civilization. This was the period for the invention of agriculture equipment, people were physically active while maintaining farms and using manual labor machines. Farming techniques improved resulting in higher quality and quantities of food. ]]> 2017-07-01 14:12:25 UTC https://padlet.com/asheffie/rrwxql9hrk52/wish/177860973 Unit 6 asheffie https://padlet.com/asheffie/rrwxql9hrk52/wish/177971698 The third revolution is also known as the Green Revolution and was a period in time when new agricultural practices were created to help farmers all over the world. It was an international effort that was planned to eliminate hunger by improving crop performances. This plan provided new practices that allowed farmers to produce more of the same product within the same amount of land. This meant that the farmers could get more out of their land than they used to. This rapid diffusion of more productive agriculture techniques occurred throughout the 1970s and the 1980s. The plan had two main practices: the introduction of newer higher-yield seeds and the expanded use of fertilizers. This would lead to the increase of the agricultural productivity at a global scale, which increased faster than population growth. The Green Revolution answered questions from experts about massive global famine.]]> 2017-07-03 20:09:25 UTC https://padlet.com/asheffie/rrwxql9hrk52/wish/177971698 Unit 7 asheffie https://padlet.com/asheffie/rrwxql9hrk52/wish/177984810 Camptotheca or the so called cancer tree is a deciduous tree native to Southern China and Tibet. It grows to a height of 20 to 25 meters tall and has a light grey bark and oval leaves with heavy pleated veining. The flowers are white to yellowish spherical clusters.   It contains pentacyclic quinolines camptothecin and 10-hydroxycamptothecin which inhibits DNA topoisomerase I and is very effective against cancer cells.]]> 2017-07-04 00:32:01 UTC https://padlet.com/asheffie/rrwxql9hrk52/wish/177984810 Unit 8 asheffie https://padlet.com/asheffie/rrwxql9hrk52/wish/177984965 Life on Earth depends on plants, algae and fungi. For humanity they are the major source of food, clothing, shelter and medicine. 
They clean our air and water, store carbon, and protect us from floods and drought.
