What is the difference between photosynthesis and respiration?

Nevertheless, more experimental trials under the same conditions would be necessary to derive more accurate rates of photosynthesis and respiration. These results are collaborated by those found on the cable web-page, specifically Beer, et al. 2001 who reported significant changes in respiration rates similar to those in this experiment. Also, t-tests for both this study and the Fink et al. 2001 study showed there are no significant differences in photosynthesis rates between germinating and non-germinating peas.

Compare and contrast photosynthesis and cellular respiration

Each experimental trial was performed at room temperature (21 - 24 degrees Celsius). This was important so that changes in photosynthesis or respiration were isolated to the peas biological processes and not due to a change in temperature. Ten non-germinating peas were weighed, then placed in a sealed bottle and the concentration of CO2 was monitored for a period of ten to twenty minutes. This time was equally divided between light and darkness and was long enough to derive an accurate slope, and consequently photosynthesis and respiration rates, from changes in CO2 concentration. Then ten germinating peas were measured, using the same procedure. A total of two runs for germinating peas and a total of two runs for non-germinating peas were completed for this experiment. The rates derived from these procedures were then divided by its groups corresponding mass. This standardized results so that quantitatively the data was equivalent among trials and not skewed by differences in mass.

Aerobic and Anaerobic Respiration - Photosynthesis …

Plants make their own food by photosynthesis. Carbon dioxide and water react together in the presence of light and chlorophyll to make glucose and oxygen. The glucose is converted into starch, fats and oils for storage. It is used to make cellulose for cell walls, and proteins for growth and repair. It is also used by the plant to release energy by respiration.

Aerobic cellular respiration creates as many as 36 ATP molecules from each glucose molecule, and anaerobic respiration creates only 2 ATP molecules.

Comparing Photosynthesis And Cellular Respiration Chart

The non-germinating peas produced rates close to zero for both photosynthesis and respiration (means were -0.331 ppm/min/g and 0.021 ppm/min/g, respectively). However, rates of photosynthesis and respiration varied for the germinating peas (means were 1.793 ppm/min/g and 18.191 ppm/min/g respectively).

The comparison between photosynthesis vs cellular respiration raw ..

The differences in photosynthesis and respiration in germinating and non-germinating peas may help us explain the adaptations plants have made to be successful organisms. Many plants generate seeds to produce their offspring and within these seeds is the genetic information they need to become mature, reproductive plants. Since these seedlings begin without roots to acquire nutrients or leaves to generate energy, an investigation into a seedlings metabolic processes may provide insight into how a seed initially survives to maturity. Therefore, if germinating peas require energy to grow and we compare photosynthesis and respiration rates between germinating and non-germinating peas then we should see higher rates of respiration and photosynthesis in the germinating peas.
