Transpiration Formal Lab Report By Jessica Tran Introduction When water is transported from the roots to the mesophyll cells in the leaves‚ it is evaporates out the stomates‚ called transpiration‚ to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomates open to release water‚ it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis

Abstract: In this Lab we used the chemical DPIP to detect the rate of succinate broken down by the mitochondrial solution. We detected the amount of DPIP in the solution with a spectrophotometer and measuring the absorbance of light at the 600nm range. DPIP is a useful chemical to use in this experiment because it goes from a blue color when oxidized to a colorless liquid (Ogura‚ 281)‚ this is due to the hydrogen ions and electrons released during the transitional step between succinate and fumarate

relationship between the amount of matter that is within a particular space. He used this knowledge to determine if a crown made for the King was in fact made of pure gold‚ which as happens was not. He discovered such knowledge when he realized that the volume of an object could be determined by the displacement of the liquid. Density is a property that will be consistent for any substance. For pure substances it is the same concept as concentration. For solutions of material density increases as the concentration

significantly faster than ethylene glycol (Hunter 1976). The hypothesis regarding hemolysis time was that the lipid/water partition coefficient would be directly correlated with speed of hemolysis‚ while molar volume would be indirectly correlated (Gardner and Godrick 2011). Therefore‚ increased molar volume would increase the hemolysis time and increased lipid/water partition coefficient would decrease the hemolysis

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

Are there any differences in the rate of metabolism of a dried yeast culture with differing carbohydrate sources? In the current practical that was undertaken the growth rate of yeast (S. cerevisiae) with differing carbohydrates sources : Glucose (C6H12O6)‚ Fructose (C6H12O6)‚ Lactose (C12H22O11)‚ Xylitol “(CHOH)3(CH2OH)2” and Water (H2O) as a Control were observed. “ Yeast are single-celled fungi which consist of more than one thousand different species which have been identified.

The Ouchterlony procedure is what will be used in this lab to detect nature of the antibody interaction. The orientations of the band will provide more information about the interaction of antibody and antigen

closer the heart rate should be to the resting heart rate of the Daphnia. Possible errors that could have gone wrong are the duration given to allow for the absorption of the different concentration of salt solutions due to the limited time during the lab period and the distinguishing of the separate heart beats and the inaccuracy of a constant time being off by points of a

Measures of Flexibility and Their Correlations to Sit-and-Reach and Modified Sit-and-Reach Tests Jacob Palmer University of Puget Sound March 3rd‚ 2015 Measures of Flexibility and Their Correlations to Sit-and-Reach and Modified Sit-and-Reach Tests INTRODUCTION Flexibility can be defined as the capability of something to bend easily without breaking. The flexibility of a person is commonly measured during fitness tests‚ and the most frequently used test of a person’s flexibility is the sit-and-reach
