Student Blog Post Assignment 3 : Biochemical Cycles and My Plants - Jessica Serrano
For the last following week, I have noticed that our plant has been getting taller each and everyday. Our cabbage plant did have some bites taken out of t due to the chickens we live next door. This however did not severely affect our plant’s long large leaves which increase the width of our plant. The leaves are so long that they seem to spread out outward. We have seen the most growth in our plant through how long the leaves of our plant are.
Our cabbage plant plays a major role in the water cycle just like many other plants in our biosphere. Precipitation cause water to fall from the sky as rain, hail, or snow. Since, San Jose, California doesn’t receive much snow or hail the water falls as rain. It is then absorbed by the soil which is surrounding our plant. This then cause our plant’s roots to soak up the water and carry it throughout the plant, such as to the leaves and stem. This water then helps perform photosynthesis which is the process of plants making their own food. The plant then is able to make itself food. Our cabbage plant has used the water cycle during photosynthesis since it needs to make itself food to survive. Our plant makes glucose using water and other sources to make its food. It then releases the water back to the atmosphere.
Our plant is a has a major importance in the carbon cycle. Plants breathe in carbon dioxide and release oxygen into the air. Humans do the opposite. They breathe in oxygen and breathe out carbon dioxide. This then balances the relationship between plant life and humans or animals. Without a source of food a plant will never grow. Since carbon dioxide is need in order to perform photosynthesis and without it our plant would have died.
Our cabbage plant also takes part of the nitrogen cycle. It take nitrogen but then stores it into the soil that is surrounding the plant. A plant’s roots absorb nitrogen which is found in soil. In order for a plant to absorb the nitrogen, nitrogen fixing bacteria is needed . When a plant dies and begins to fossilize , the plant puts nitrogen back into the soil since it is decomposing. Fungi and bacteria decompose the plant, which bury the carcass of the plant deeper into the earth.
