Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

“Investigate the factors affecting the rate of yeast respiration” Lab Report Introduction The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three‚ along with glucose and galactose‚ dietary monosaccharides that

for waste is carbon dioxide (CO2) and water (H2O). CO2 can combine with water to form carbonic acid during cellular respiration. Phenolphthalein can be used to help detect any changes in pH because of production of CO2 during cellular respiration. Phenolphthalein usually appears clear or colorless in acidic solutions‚ and red in basic solutions. Procedures: In the first lab‚ seven test tubes were attained and six of them were filled with the solutions that were listed (Na Pyruvate‚ MgSO4

The main objective of this lab is to see if the rate of cellular respiration will be affected if we change the food source from glucose to three different experimental variables (fructose‚ sucrose‚ lactose). Cellular Respiration is a process that generates ATP and it involves the complete breakdown of glucose to carbon dioxide and water. Carbohydrates‚ fats‚ and proteins can all be used as fuels in cellular respiration‚ but glucose is most commonly used as an example to examine the reactions and

For information on how this assignment will be graded‚ please visit the Course Information sectionChlorophyll and Accessory Pigments A pigment is any substance that absorbs light. The color we see comes from the wavelengths of light that reflect. Chlorophyll‚ the green pigment common to all photosynthetic cells‚ absorbs all wavelengths of visible light except green. The green reflects back to our eyes

Elodea & Photosynthesis Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. Introduction This lab has been created in order to find what extent does distance from a light source (5cm‚ 10cm‚ and 15cm) affect the rate of photosynthesis (measured in bubbles / 3 min) in Elodea water plants. Hypothesis:

Title: Effects of Light on Photosynthesis Introduction: Photosynthesis is the complex process by which carbon dioxide and water are used to make carbohydrates by using light energy in green plants. The objective of this experiment is to measure the rate of photosynthesis Hypothesis: The petri dish that is exposed to the most light and with the NaHCO3 solution will have the best results and the petri dish that is kept in the dark will have the poorest results.

Introduction: Photosynthesis is a process to which some autotrophs such as plants produce their own food. It has two stages or reactions light-dependent and light-dependent reactions. The light dependent reactions are the first stage‚ where energy from sunlight is captures in Photosystem 2 and then 1‚ the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP‚ by the

measured to determine the rate of photosynthesis. This experiment was set up to discover how different wavelengths of light affect the rate of photosynthesis in a spinach‚ DPIP‚ phosphate solution. I proposed that the spinach‚ DPIP‚ phosphate solution under no filter‚ and therefore exposed to all light will have a highest percent orange light transmittance and a highest rate of photosynthesis. The solution under the red filter will have the next highest rate of photosynthesis‚ then the solution under the
