The energy they absorb during photosynthesis is the source of energy that animals use later as they eat the plants and/or other animals. Without plants, animals would have no way to receive energy from the sun. In a way, plants serve as the foundation of the food chain, much like how these beams are supporting the structure. Plants serve a similar function in society, as well: As humans developed better ways to farm plants, they were better able to settle down, instead of having to search for plants in nature. The cultivation of plants helps humanity settle down and develop different cultures. In a sense, plants serve as a foundation for society, as well: Once farming allowed humans to settle down, they could build their societies from that point forward. ]]> 2018-01-17 18:58:24 UTC https://padlet.com/arober33/owdstp61rn9f/wish/222193053 arober33 https://padlet.com/arober33/owdstp61rn9f/wish/238960899 By Crash Course. ]]> 2018-03-07 01:10:45 UTC https://padlet.com/arober33/owdstp61rn9f/wish/238960899 arober33 https://padlet.com/arober33/owdstp61rn9f/wish/238961061 To me, this video describes the complex details of photosynthesis in an enjoyable way, with many illustrations in order to make the concept more digestable. The narrator explains the processes with an animated tone, which helps generate interest in the process of photosynthesis. I also chose this video because it not only describes photosynthesis, but it also covers the intricate details of the process. For someone in a college level course that covers the intricacies of photosynthesis, this video is a helpful source to use when studying. ]]> 2018-03-07 01:11:29 UTC https://padlet.com/arober33/owdstp61rn9f/wish/238961061 arober33 https://padlet.com/arober33/owdstp61rn9f/wish/238961283 The American Holly tree (Ilex Opaca) is an evergreen tree native to the central and eastern United States, including Georgia. It bears its seeds on female trees in berry-like fruits called "drupes," and thus it is an angiosperm. People use these drupes as a decoration during the winter, which is when these drupes are ripened.]]> 2018-03-07 01:12:25 UTC https://padlet.com/arober33/owdstp61rn9f/wish/238961283 arober33 https://padlet.com/arober33/owdstp61rn9f/wish/238982568 To me, the arctic tundra is the biome that is at the most risk of ecological distubances. I believe that the effects of global warming have the potential to disrupt the stability of the tundra environment and cause it to get hotter. In turn, this could melt the snow and expose the plants and animals there to conditions to which they have not adapted, which would eventually lead to their extinction. The melting ice would also cause these areas to be exposed to excess amounts of water. ]]> 2018-03-07 03:02:29 UTC https://padlet.com/arober33/owdstp61rn9f/wish/238982568 arober33 https://padlet.com/arober33/owdstp61rn9f/wish/244317696 This graph by genetics professor Spencer Wells shows the "burden" of three different conditions affecting humanity since the agricultural revolution: trauma, infectious diseases, and chronic diseases. As the graph  shows, the rate of infectious and chronic diseases increased after the Neolithic Revolution. When early humans discovered how to cultivate crops, they began to live in larger settlements, closer with both farm animals and each other. These larger settlements made it easier for diseases to spread between people, and this led to the increase of epidemics. Epidemics lead to a constant looming threat to the stability of human civilizations, which caused the death of billions of people over centuries. The threat of diseases are also what led to humanity's efforts to create a sanitary living environment: With cleaner cities, diseases were less likely to spread. ]]> 2018-03-21 00:10:20 UTC https://padlet.com/arober33/owdstp61rn9f/wish/244317696 arober33 https://padlet.com/arober33/owdstp61rn9f/wish/249490917 Within the past century, scientists have discovered gentic markers that correlate with how traits appear in plants. With this knowledge, scientists around the world are able to directly manipulate plants to achieve a desired result. The video gives an example of plants being able to naturally produce a chemical that can kill pests, saving the need for pesticides. After the discovery of gene editing, people could now manipulate crops to make them more appealing to buyers. Thus, the genetic editing of plants led to a greater number of "good" plants for countries to trade with each other. In today's global society, GMO's allow farmers to grow the "ideal" type of a crop; in turn, this leads to the crop being grown in greater numbers. The genetic editing of plants has allowed countries to have a greater number of crops to trade with each other, which in turn helps support the 7 billion people on the earth. ]]> 2018-04-08 05:47:37 UTC https://padlet.com/arober33/owdstp61rn9f/wish/249490917 arober33 https://padlet.com/arober33/owdstp61rn9f/wish/251973099 Ethanol is a chemical compound that is derived by the fermentation of certain plants (including grapes or corn). It is most widely used to depress the nervous system in many alcoholic beverages, including beer and wine. Thus, ethanol is what makes alcoholic beverages addictive. Since alcohol has been one of the most widely-used drinks in history, and its effects have been affecting humanity for centuries, I believe that ehtanol is the most influential chemical derived from plantlife. The attached video further discusses the science and history of beverages made with ethanol.]]> 2018-04-16 02:31:22 UTC https://padlet.com/arober33/owdstp61rn9f/wish/251973099 arober33 https://padlet.com/arober33/owdstp61rn9f/wish/255422470 Two of the main concerns people currently have about climate change is the deforestation of trees and the increase in temperature due to global warming. The temperature rise, in turn, has placed the ice torwards the poles at risk of melting, which could raise the water levels to catastrophic levels, leading to destruction of many human cities on the coasts. To me, this picture illustrates what could happen if both of those situations occur: Not only is this area flooded, it is also devoid of any plantlife. Thus, I feel like this is a good representation of how the future might look if society as a whole doesn't attempt to work to improve their environmental policies. ]]> 2018-04-25 19:52:51 UTC https://padlet.com/arober33/owdstp61rn9f/wish/255422470
