c3 and c4 plants

A detailed Summary of c3 and c4 plants

C3 and C4 plants have two things in common, they both are found in hot and very dry areas and they both use photorespiration. However, the difference is the way they react toward water loss which will affect photosynthesis. If a C3 plant starts to transpire rapidly because it is photosynthesizing and the stomata are open, then it will close the stomata, ending photosynthesis. What the plant does next is undergo a counterproductive cycle called photorespiration. In the C3 plant photorespiration actually uses up 50% of the CO2 fixed by the Calvin cycle. What happens is the plant closes it's stomata and as a result stops transpiration and photosynthesis. What happens is the O2 level rises and the CO2 drops. Then the plant must use O2 in place of CO2 to input into the Calvin cycle. A two carbon molecule comes out and is broken down by peroxisomes into CO2. This just uses up CO2 and doesn't benefit the plant because no energy or food is made in this process. In a C4 plant it is different. When it needs to close it's stoma to stop transpiration, it undergoes photorespiration as well, however, it's photorespiration is productive. Preceding the Calvin Cycle

In the modern world evolution is being sped up at an alarming rate with all our new advances in the sciences and genetical engineering. We are making things we didn't even know we could like germ resistant seeds. The great thing about this biotechnology is that we are making good advances to help people like bean weevil resistant beans so that entire crops of beans will not be lost due to the bean weevil and that pretty much saved a whole village. Another great thing about these new genetically engineered plants that won't let bugs touch them is that we don't have to use pesticides because the plant defends itself. Some more possibilities would be engineering a plant that was resistant to cold whether. The advantages of this would be plants in Russia because they could now survive the cold they could boost Russia's economy because they would have good crops to sell. The disadvantages of this would be putting this exotic plant in a different country could have serious economic repercussions. For example since there would be no natural predator this plant could grow out of control like the garlic mustard or Black Eyed Susan's. A seedless fruit would b
