Recommended: Importance of photosynthesis in our life

ANSWERS TO QUESTIONS

1: What is a photoautotroph?
Answer: An organism that produces organic molecules from inorganic molecules using light

2: Which photosynthetic processes occur in the stroma and thylakoids, respectively?
Answer: Calvin Cycle in the Stroma, Chemiosmosis/light reaction in thylakoids.

3: What is the difference between Photosystems I and II?
Answer: Photosystem II activates at a lower wavelength of light than Photosystem I.

4: Why is photosynthesis important?
Answer: It produces glucose (sugar), which is the basis for most food chains, oxygen, which is necessary for breathing, and energy so that other organisms can function.

5: Where do the materials needed for photosynthesis come from?
Answer: Water goes to the leaf through

    16. Describe two evolutionary consequences if the process of crossing over in meiosis ceased to occur. If crossing over in meiosis ceased to occur there would be less genetic variations and no diversity among a species. This would essentially mean that a species would not be able to adapt to an issue that could arise in the future, meaning that its species could potentially become extinct due to climate change or other arising events.

    In Ap biology, we were handed a Campbell Textbook before the class began in order to complete the pre-modules. I consider the textbook to be the most beneficial resource that we had during this course, due to the amount of detail, examples, and images that it contained explaining each concepts in a reliable way. The power points that were made to summarize the main points from the textbook were helpful, however they were really long and made me miss what was actually important and take additional notes on filler information. Due to the long powerpoints, I felt implied to take long and details notes, which people struggled in this class, either taking too much or too less. After two units passed, we were taught how our notes should be, which will later help us in college. This strategy allowed me to understand the important information and identify the filler information, resulting in

    Most of our data supported the hypothesis. The average DO concentration is 8.3 ppm, which is between the optimal range of 8 – 12 ppm, suggesting that the aquatic organisms have a rather healthy life with abundant amount of oxygen provided to them. The average temperature is 20, which is rather cool considering that the river was exposed to sunlight and the actual temperature we felt on that day. But it is also reasonable, since the river was flowing swiftly due to the windy weather, which reduces the amount of sunlight it absorbed. Also there were trees near the river that provided shade for the river, and we got the sample from the shaded area. The average alkalinity level is 120.8 ppm, which exceeds 80 ppm, indicating a well-buffered stream.

    Fermentation is an anaerobic process in which fuel molecules are broken down to create pyruvate and ATP molecules (Alberts, 1998). Both pyruvate and ATP are major energy sources used by the cell to do a variety of things. For example, ATP is used in cell division to divide the chromosomes (Alberts, 1998).

    Since plants lay dormant for their entire lives and lack any sort of hole to consume food, they need some sort of way to produce energy to survive and continue to grow. That is where photosynthesis comes in. During the process of photosynthesis, energy from the sun is taken in to the plant along with carbon dioxide and water in order to produce glucose (sugar energy) along with oxygen. This sugar will later be used by other parts of the cell in the process of cellular respiration to use up the energy that was made.

    Oxygen (O) is one of the most important ions present in the body, making up 61% of the body’s mass. It aids in the destruction of harmful bacteria, while preserving the bacteria that is beneficial for the body. Oxygen takes on its role, and transfers the bacteria absorbed into the lungs, to the cells, allowing for cell respiration. Oxygen allows for the replacement of old cells, protection of the new ones, production of energy from the food, and decomposition of other foods (“Oxygen and Human Body,” n.d.). Oxygen is also vital to produce an activity known as metabolism, which is ‘the sum of the physical and chemical processes in an organism by which its material substance is ...

    Whenever you eat a meal, your body is working to break down the nutrients you have eaten. It then becomes energy that your body will need. This process is called metabolism. Metabolism is an important for all living things. Without it, we would not be able to break down our food into energy. No energy means not being able to keep a balanced lifestyle, and not having a balanced lifestyle can lead to illness and diseases that can affect our lives.
