Assignment 3

      This week our plant has grown a couple inches taller and has more and bigger leaves.  It is growing more upward more than outward.  The leaves were more spread out and the veins were more prominent.  The whole plant was purple too.


     Our plant contributes the the movement of water in the biosphere by absorbing water and breaking it apart the releasing the oxygen back into the air. The plant then uses the new hydrogen to grow bigger and taller and get more leaves.  This is what our plant did over the week and continuously.

      Also the plant helps move carbon around the atmosphere.  The plant takes the carbon from the sun using photosynthesis.  The plant then stores the carbon and uses it to grow bigger.  When the plant dies it will be buried the turn into fossil fuels and when we burn those fuels, carbon is released into the air to start over again.

       Another cycle my plant contributes in is the nitrogen cycle.  My plant absorbs the nitrogen from the soil and then when we eat the plants we absorb the nitrogen from the plant.  Then when we defecate the nitrogen goes back into the ground to be used by plants again.
