Cellular Respiration Lab Report

In life, photosynthesis and cellular respiration are two processes that allow life to survive. It is a cycle that uses each others reactants and products to fuel each other. The release of carbon dioxide and oxygen through photosynthesis or cellular respiration help the atmosphere stay stable. All cells in plants and animals perform cellular respiration to maintain homeostasis and grow. Cellular respiration harvests energy in glucose to produce ATP, which powers the cell. Without energy, organisms are unable to grow and the entire population is disrupted. Oxygen gas is absorbed and is converted into C02 during this process. In this investigation, three types of beans(non-germinated, germinated, and black eye peas) were tested in order to determine rate of cellular respiration. Germinated seeds are water-soaked and non-germinated seeds are dry. To test the rate of cellular respiration, we used an instrument called the respirometer, which measures relative volume as oxygen is consumed. …show more content…

They were tested for 7.5 minutes using the respirometer and they slowly lost around 48.681ppm of C02 after the test concluded. After these seeds were tested, the germinated seeds were tested for the same reason. Although the non-germinated seeds were slow to produce C02, the germinated seeds produced 524.289ppm of C02 over a span of 5 minutes. The germinated seeds have a higher respiration rate because it has stored water and it helps them respire a lot more. Having both versions of this type of seed allow us to understand how cellular respiration varies based on the type of seed and germination. To test this further, we tested black eye peas for their rate of respiration. This type of seed produced very little C02 because they did not germinate quickly, therefore were unable to produce as much

Pinto Bean Seedlings Experiment

1354 Words | 6 Pages

Hypothesis: If one-day pinto bean seedlings are soaked in a water solution, 1% NaCl solution, and 3% NaCl solution, the seedlings exposed to higher sodium concentrations will have decreased cellular respiration rates. Treatments: This experiment involved three treatments and a control. The goal of the experiment was to see how different levels of NaCl affect the rates of cellular respiration in day-old pinto bean seedlings.

02.06 Introduction To Photosynthesis Lab Report

276 Words | 2 Pages

Transitioning between photosynthesis and respiration : CO2 cuts into carbon and oxygen, some of the oxygen is then released and the carbon mixes with H20. If it was mad and balanced, the effect of carbon and water will also affect glucose. This is called photosynthesis. Plants take the water and CO2 in order to make food (glucose) which sets the oxygen free.

Biology: Photosynthesis And Respiration

593 Words | 3 Pages

As stated in the background of the lab, "seeds are considered to be in a period of dormancy, where they metabolize stored energy at a very slow rate while the seed is still considered alive" (Hands On Labs). During germination, the developing plant embryo uses the stored food supply in the seed for cellular energy and growth. Thus, cellular respiration is taking place as the seeds grow. Without water the seeds cannot begin germinating thus the seeds in test tube N did not undergo photosynthesis(Hands On Labs). B. Were the seeds in the “G” tube undergoing both photosynthesis and respiration, only photosynthesis, or only respiration?

Spinach Lab

484 Words | 2 Pages

The purpose of this lab was to test the rate of photosynthesis in cut-out circles of spinach leaves in a solution with only water and a solution with water and carbon dioxide. The hypothesis made for this experiment was that the circles of spinach leaf that were placed in the solution with the carbon dioxide would float to the top more quickly than the circles of spinach leaf that were placed in just water. To test this hypothesis, twenty circles were cut with a hole punch from a spinach leaf in order to have a plant to perform the photosynthesis. Considering plants have oxygen running through their veins, the oxygen had to be taken out of the spinach circles before completing the experiment. To do that, the spinach circles were put into a syringe along with 5 mL of the solution in which they were going to be submerged.

Spinach Leaf Photosynthesis Lab Report

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.

Respiration In Crickets Lab Report

1667 Words | 7 Pages

For example, in trials one and two of this test the respiration rates were zero. Technically, the rates shouldn’t be at exactly 0 ppm/s because the crickets were alive and therefore respiring, so this information could implicate that the bottle containing the crickets was not completely airtight while the CO2 sensor was reading. However, in trials three, four, and five, the rates also stay within the range of 0 and 0.3 ppm/s, so the inference that is made is that in the lower temperature the crickets will not respire as much as in the higher temperatures. In 35oC, the crickets respired quickly at rates that, when compared to the lower temperature, were on average, much higher. For example, in trial one the crickets respired at 1.12 parts per million which is about one part per million higher than when the crickets were placed in 5oC.

Compare And Contrast Cellular Respiration And Photosynthesis

420 Words | 2 Pages

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.

Overall, the experimental hypothesis proved to be correct. The amount of cellular respiration did increase in the germinating seeds compared to the ungerminated seeds. The results showed the germinating seeds producing carbon dioxide in the closed system. The germinated seeds respired for four minutes before stopping.

The purpose of the transpiration lab was to expand and test one’s knowledge on transpiration, and how it is affected by various factors. This was done in an experiment involving five pansy plants. These pansies were placed into five separate environments with different factors labeled as Control, Intense Light, Humidity, Fan, and Dark. The objective of the lab was to determine how and explain why each environment affected the transpiration of their individual pansey. The main scientific principle being explored in this lab was transpiration.

This is very similar and related to the previously discussed objective of being able to identify biological processes that require energy. Modeling the way organisms capture and store free energy was achieved in several different labs, including the cellular respiration lab. In the lab, we modeled how an organism can capture and use energy through facilitating the germination of seeds. Germination is a very complex biological process that requires the capture and storage of energy for later use. Modeling this process allows further investigation and greater understanding of how energy is captured and used by

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.
