Photosynthetic saturation is the maximum rate of photosynthesis. What was the value for photosynthetic saturation in tomato leaves? Answer Light quality does not effect the rate of photosynthesis. Answer Based on what you know about photosynthesis‚ provide possible reasons for what causes photosynthetic saturation (these cannot be determined from the graph). Answer Which color of visible light was least effective for photosynthesis? Answer What is the relationship

Section 1 Purpose: The purpose of this lab was to separate plant pigments using chromatography‚ calculate Rf values using the collected data‚ and study photosynthesis with isolated chloroplasts. Light energy Light energy Background Information (Activity A): In photosynthesis‚ plant cells convert light energy into chemical energy that is stored in sugars and other organic compounds. It is an endergonic and anaerobic reaction. Critical to the process is chlorophyll‚ the primary photosynthetic pigment

contained in a liter of water. If you put these organisms in a bottle and turn on the lights‚ you get photosynthesis. If you turn off the lights‚ you turn off the primary production. Darkness has no effect on respiration. This is because cellular respiration is actually the reverse process of photosynthesis. Oxygen is a necessity of life requirements for basically all living organisms.* In this lab we are testing how different levels of salinity in the water indirectly affects the gross primary productivity

Based off the results from this lab the student was able to determine and have an overall better understanding of the variables that affect the rate of photosynthesis in a plant. The first variable the student tested in the lab was 30cm of light with CO2 present. The student started this trial with all 10-leaf disks and timed how many leaf disks came up every minute for 15 minutes. One minute into the trial and the student recorded that no leaf disks had yet to rise to the top of the solution. At

Labset Three Worksheet 1. What is a carbohydrate profile? Why are they used as a diagnostic or identifying tool? (2) Carbohydrate profiles are specific information on the type and amount of carbohydrate that a product contains. It is used to identify and differentiate two closely related species. 2. What are the carbohydrate profiles of the organisms you tested? (2) The yeast carbohydrate profile came out with glucose and fructose positive and Mannitol negative. The staph epidermidis

Sang Kim Enzyme Catalyst Purpose/Problem: There are four parts to the Enzyme Catalyst lab - Activity A‚ B‚ C‚ and D. In activity A‚ the characteristics of enzyme actions will be observed. The main purposes are to determine the rate of an enzyme catalyzed reaction‚ to study the characteristics of an enzyme mediated reaction‚ and to observe the effect of heat on enzyme activity. The purpose of activity B is to use the Titration Protocol to determine the initial amount of H 2O2 present

Chapter 11: Cell Communication Cell-to-cell communication is essential in multicellular organisms. They must communicate to coordinate activities such as growth and development‚ and reproduction. In addition unicellular organisms communicate with each other. Signals may use light‚ or touch but we will focus on chemical signals. 1. External signals are converted to responses within the cell a. Evolution of cell signaling i. In yeast a cells and αcells both secrete chemicals

Iso osmolar can be known as the point in which the substance of experimentation faces no change despite the amount of solute inside the solvent( because the solvent and solute concentration is equal. This is where the line on a graph would cross on the
