Photosynthesis takes place in the chloroplasts; green organelles inside plant cells. The thylakoid inside Chloroplasts absorb the sunlight energy needed for photosynthesis. The pigment in the thylakoid absorbs light; however, plants reflect green light. This gives plants their color. If different colors of light are shown on spinach leaves and CO2 consumption is measured, then the spinach leaves given green light will consume the least amount of CO2 due to reduced photosynthesis activity.
Alexandra Fowler Due: 10/25/2015 Metabolism Exam Answer the following questions as completely and concisely as possible. Some answers may be a single word, but for more detailed responses, keep you answer to 3 sentences or less. What is the electron donor of an organism growing chemorganotrophically? The electron donor of an organism growing chemorganotrophically is an organic compound such as glucose, acetate, etc.
A. Were the seeds in the “N” tube undergoing both photosynthesis and respiration, only photosynthesis, or only respiration? Use your results in Data Table 2 to support your answer. The seeds in test tube "N" underwent respiration. Respiration is always happening.
The process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die. Earth would lack the oxygen and energy that plant life provides. Producers are the main source of energy for living organisms because they can directly absorb light energy and turn it into chemical energy. Animals then eat the plants which give them a portion of that energy.
photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.
They can balance hormones and brain chemistry. They can stimulate the regeneration of tissue and stimulate nerves. They can even carry nutrients to and oxygenate the cells.
Task 1 When you exhale onto a window it steams up because your breath contains water vapour and it causes water vapour to condense forming small water droplets. We breathe in oxygen and some nitrogen which is essential for life. We exhale carbon dioxide that can be tested for limewater because carbon dioxide dissolves in water to form carbonic acid (H2 C03). Glucose is a reactant of respiration.
Energy is also needed to circulate blood, breath, take in oxygen, make new cells, grow, repair, and to transmit nerve impulses to react to changes in the environment. For example, moving quickly to get out of danger or recognising the best course of action to take in an emergency situation. Energy is also needed to build complex molecules such as enzymes and hormones from the simple molecules produced after we digest food and drink. A constant supply of energy is needed by the body and cells to enable all of these activities, and without this energy we would be unable to function as living beings.
Cellular respiration can be measured by the consumption of oxygen, the consumption of carbon dioxide, and the release of energy during cellular respiration. Within the experiment conducted, the relative volume of O2 consumed was measured into different temperatures within germinating and nongerminating peas, (DeStefano). Fluids and gas flow from regions of high-pressure to regions of low-pressure this carbon dioxide produced during cellular respiration will be removed by potassium hydroxide and will form a solid potassium carbonate. Due to the removal of carbon dioxide, the change in the volume of gas in the respirometer will be directly related to the amount of oxygen consumed. In this experiment using a respirometer, the scientists were able to measure the amount of oxygen being consumed in relation to how quickly the peas were respiring.
+ ATP Although plants and animals have different methods of obtaining glucose, the cell respiration process occurs in both types of organisms. Many external factors in the environment may affect the organism's’ rate of respiration such as the temperature of the surrounding,
The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.
Quinn Nguyen Floating Leaf Disk Photosynthesis Lab Conclusion: Graph your results for all 3 trials on one graph. Label the graph, both axes, and provide a legend to distinguish each trial. What was the rate of photosynthesis for each variable? How many leaves floated per minute? Rate of photosynthesis (leaves/min) Spinach: (2-0)/25 = 0.08
One of the focuses of this semester was the ability to identify biological processes that require energy and explain why they require energy. In the work I completed I demonstrated being able to accomplish this. This occurred in several different projects, including the cellular respiration lab involving the respiration rate of germinating seeds, the potato core lab and the photosynthesis lab. In these labs, we were able to identify the biological processes that required energy for the different processes to take place to allow germination to occur.
Cellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.
Research Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases.
