How our collards have






                       Over the past few weeks 4-2 collards have grown tremendously. From a tinny little seed they have blossomed into beautiful luscious leaves. They have transformed from a little seedling into a ready to harvest vegetable. However, we had a little help from sun to start of a cycle known non other then photosynthesis. Thanks to the sun trickling down its golden rays the light dependent reactions could occur. This when the energy is taken from the sun's rays and converted into oxygen, NADPH, and ATP. All this happens in the thylakode membrane. After all that the plant is not even close to being down. The calvin cycle still needs to occur. This is when six carbon molecules are combined with 5 carbon molecules to produce twelve 3 carbon molecule. Then, energy from ATP and energy from high energy electrons from NADPH are used to convert the tweleve 3-carbon molecules into high energy forms. Two of these 3-carbon molecules are used to make a 6-carbon sugar. The 10 remaining molecules are converted back into six 5-carbon molecules, which are used in the next cycle.
