Biology Investigation Problem: How does light affect the rate of Photosynthesis? The Plan In my experiment I am going to see how light affects the rate of photosynthesis. To do this experiment I am going to set up the apparatus as shown in figure 1. The apparatus I am going to use are the following: - 1 Tripod 1 300ml Beaker 1 Boiling Tube 1 Clamp Stand 1Clamp 1 Boss 1 Ring Binder 1 Lamp 1 1 Metre Ruler 1 Thermometer 1 Stop Clock To do the experiment I will set up the apparatus first.

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

Lab 4: Photosynthesis and Chromatography of Spinach Leaves Discussion: The chromatography of the spinach leaves was taken to establish what pigments were present in the chloroplasts of the leaves. The solvent carried and separated the different pigments up the cellulose paper. The solvent moved up the paper because of capillary action because of adhesion of the solvent molecules and the paper. The pigments dissolved in the solvent also were carried up the paper and were separated because

Organisms through cellular respiration convert energy into ATP. They do this in three distinct stages; glycolysis‚the Krebs cycle and the electron transport chain. The Krebs cycle and electron transport chain are both aerobic process and require oxygen. In certain conditions where oxygen is not present or is low some organisms switch from cellular respiration into alcoholic or lactic acid fermentation. Fermentation is an anaerobic‚ metabolic pathway used to oxidize nicotinamide adenine

According to the website www.tutorvista.com‚ Prokaryotes differ from eukaryotes in their structure‚ packing‚ density‚ and arrangement of their genes on the chromosome. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the cell wall‚ and the structure of chromosomal DNA. All cells share some common characteristics that make them living things and all organisms are composed of cells which are the basic fundamental unit of life.

process of respiration happens in many organisms and species. For the lab study that we are going to conduct I choose Yeast as my organism. First off Yeast is a microscopic fungus consisting of single oval cells that reproduce by budding or fission (is the splitting of an atom)‚ and capable of converting sugar into alcohol and carbon dioxide. When making your own bread‚ you can buy yeast in the grocery store. The yeast contains little brown grains that will carry out cellular respiration and grow when

Summary- The Statistics from the University of Valencia(UV) states that bullying from a cellular device affects teenagers. The preponderance of the cases seems to tell that the abuse of cyber bullying lasts for a month or less. When bullying last more than three months it is most likely the form of using a cellular device. It is most common for students/children to get bullied their first years at school by phones and the internet. The statistics from(UV) show that girls suffer more bullying than

Photosynthesis and Semi-Conductor based Solar Cells Plants‚ by shear desire to survive have developed the worlds most efficient and reliable power supply by way of photosynthesis. Scientist for years have tried unsuccessfully to duplicate the process of photosynthesis. However‚ for the purpose of this paper‚ I will compare and contrast how energy and electricity is generated through photosynthesis and a semi-conductor based solar cell. In addition‚ this paper will explain how both processes
