Post assignment #3 : Elena

Over the course of the week our two little seedlings are growing up into healthy broccolis. So far one of them has grown pretty tall and has two stems that are attached. Both seedlings have grown a little thicker and a little taller. They have grown many leaves that are heart shaped, making it easy to tell them apart from weeds. The seedlings are a light green color. We hope that our little brocs will continue their growth to become healthy big broccolis.

Out plants participate in the movement of water in the biosphere by absorbing water through their roots. This process is called root uptake. Our seedling’s leaves also catch rain and the water droplets are evaporated via: transportation. The water that our plant absorbs helps it with photosynthesis, growing and developing. The water gives the plant nutrients to grow. This has allowed our plant to grow taller and bigger leaves.

Our plants participate in the movement of carbon in the biosphere by absorbing it through its leaves and using the carbon and water for photosynthesis. Our plant uses the carbon for photosynthesis to get the nutrients, which has allowed it to grow new leaves and get bigger. Usually plants will take in carbon dioxide but when plants die they loose all the carbon that they had stored and is released into the atmosphere.

Our plants participate in the Nitrogen cycle.  Bacteria in the soil converts the nitrogen to ammonia, the ammonia is then changed into nitrates which can then be taken up by the plants. The plants have gotten to grow bigger stems and bigger leaves which are taking to a heart shape. After the plant has absorbed the ammonium and nitrates using it for nutrients a process called ammonification happens. Bacteria in the soil will convert the nitrogen nutrients back into ammonia, from there bacteria will also convert the ammonia to nitrogen gas, this process is called denitrification.
