20.1 KEY CONCEPT-Plant life began in the water and became adapted to land. Plants are multicellular eukaryotes‚ most of which produce their own food through photosynthesis and have adapted to life on land. Plants share many characteristics with green algae. Both are photosynthetic eukaryotes with the same types of chlorophyll. Both also use starch as a storage product and have cell walls that contain cellulose. One ancient species of green algae is the common ancestor of all plants. If it were

According to the New Oxford American Dictionary this means an organism containing genetic material that has been artificially altered so as to produce a desired characteristic. Generally‚ genetic modification happens one of two ways. One‚ picks the organism with desired traits and breed it was another with the same physical traits‚ making the desired traits

In a recent study‚ it was found that‚ “The upshot of [Genetically modified organisms] is that 50% of all children in the United States now have chronic diseases and 21% suffer from developmental disorders” (Ferrie 13). This epidemic stems from the fact that GMOs are detrimental to nature and humanity because they destroy ecosystems‚ cause illnesses in humans‚ and spread their genes to organisms that has not yet been modified genetically. One of the most important ways that GMOs hurt nature is by
