Effects of Photosynthesis of Spinach Leaves in Different Light Conditions Introduction Photosynthesis is the process of converting solar energy‚ carbon dioxide (CO2)‚ and water (H2O) into carbohydrates (CH2O) and oxygen (O2). Sometimes the end product of photosynthesis is glucose (C6H12O6). Photosynthesis takes place in the chloroplasts of plant cells. Here membranous thylakoids are stacked in grana surrounded by the stroma. During the light reactions‚ pigments within the thylakoid membranes

The scientific Method 1. Scientific Method- scientific investigation involving the observation of phenomena‚ the formulation of a hypothesis concerning the phenomena‚ experimentation to demonstrate the truth or falseness of the hypothesis‚ and result that validates or modify the hypothesis. Mechanist- Has belief that only natural forces govern living things‚ along with the rest of the universe. Vitalist- believes that the universe is at least partially governed by supernatural powers.

Chapter 6 DIFFUSION IN SOLIDS • How does diffusion occur? • Why is it an important part of processing? • How can the rate of diffusion be predicted for some simple cases? • How does diffusion depend on structure and temperature? Driving force for movement In general‚ force is a position derivative of energy (F = - dE/dr). In other words‚ if there is any energy difference in space‚ there is a force which will act on matters - Force will move things. (ex1) Potential energy by gravity:

Photosynthesis Investigation Research Question How does length of pondweed affect the amount of bubbles produced in 2 minutes by pondweed during the process of photosynthesis? Independent variable: Length of pondweed (8/10/12 cm). Dependent variables: amount of bubbles produced in 2 minutes. Control variables: Volume of water in the beaker (500ml)‚ The volume of water has to be the same every time‚ so when doing the experiment I need to make sure I always use these 500 ml that i have already

Discovery of PHB... Polyhydroxybutyrate‚ or PHB‚ was discovered in 1926 by French microbiologist‚ Maurice Lemoigne‚ who was researching the use of bacteria to produce polyesters‚ at the time. However‚ it was overlooked and forgotten for over 30 years‚ as there wasn’t any need for such a biopolymer; petroleum was still inexpensive and abundant so PHB was unnecessary. In 1957‚ PHB was rediscovered in Britain and USA‚ and was further developed and researched during the 1960s. The mass production

intensity on the rate of photosynthesis. What is Photosynthesis? Photosynthesis is how plants get their food. The reason why plants have leaves‚ roots or being green is all linked to photosynthesis. In photosynthesis‚ a plant takes carbon dioxide from the air and water from the soil and uses the light from sunlight to turn them into food. Photosynthesis occurs only in the presence of light‚ and takes place in the chloroplasts of green plant cells. Photosynthesis can be defined as the production

Delphi method∗ Abstract The Delphi method was originally developed in the 50s by the RAND Corporation in Santa Monica‚ California. This approach consists of a survey conducted in two or more rounds and provides the participants in the second round with the results of the first so that they can alter the original assessments if they want to - or stick to their previous opinion. Nobody ‘looses face’ because the survey is done anonymously using a questionnaire (the first Delphis were panels)

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity
