How does the Amount of CO2 Affect the Rate of Photosynthesis? There are a number of variables that can affect the photosynthesis rate of Canadian water weed (Elodea). They are as follows:  The amount of light: an increased light level increases the rate of photosynthesis to a certain point where at another factor limits the photosynthesis rate.  The temperature: Increased temperature increases the rate of photosynthesis to a certain temperature‚ after which‚ essential enzymes

Effects of Activators and Ethanol on Fermentation Rates In this lab we examined how the rate of fermentation is influenced by the type of substrate‚ and activators and inhibitors. We used four fermentation tubes in which we separately combined yeast with MgSO4‚ pyruvate‚ ethanol‚ and glucose. At five minute intervals we recorded the volume of gas produced in each fermentation tube. Our results are displayed in the graph. Our results supported the prediction that pyruvate is an activator

diversity will fall. All three of the plants will grow but the height will differ between the control‚ moderate and high plants. The control will have a lower height‚ the moderate will be higher and the high will have the highest height. With the Elodea densa‚ Eutrophication will occur in all three aquariums. All three will be different because of the different types of fertilizer. Control will have no pollution‚ the moderate tank will have some‚ and the high tank will have a lot because of the

In the Kingdom Exploration lab‚ five different organisms were observed under a microscope‚ (Yeast‚ Paramecium‚ Elodea‚ Daphnia‚ Euglena). Each of these organisms is apart of one of the six kingdoms‚ (Eubacteria‚ Archaebacteria‚ Fungi‚ Protista‚ Plantae‚ and Animalia) which are apart of three domains‚ (Archaea‚ Bacteria‚ and Eukarya). In this lab‚ however‚ none of the organisms observed were archaea or bacteria. Also‚ all the organisms were eukaryotes‚ not prokaryotes‚ which are organisms without
Premium Photosynthesis Carbon dioxide Oxygen
amount of oxygen produced by Elodea (Canadian pond weed) in the process of photosynthesis? Hypothesis: If there is an increase in concentration of sodium bicarbonate the amount of oxygen produced will increase because the sodium bicarbonate concentration will increase the carbon dioxide levels. Independent variable- Concentrations of sodium bicarbonate (8%‚6%‚4%‚2% 0%) Dependent variable- Amount of oxygen collected in the measuring cylinder. Controlled variables- 6cm Elodea‚ Run for the same time (48

Transport Systems Essay In single celled organisms‚ nutrients‚ water and various substances that are need for basic cellular processes can easily be transported in and out through the cell membrane. This is an effective transport system for microscopic organisms‚ but multicellular organisms require a more complex transport system to sustain itself. Take humans for example; unlike a cell‚ only the outer layer of skin is in contact with the body’s outside environment. It’s not possible for substances

Lab Questions: Lab #4 * Why are the chloroplasts traveling along the outer perimeter of the Elodea cell? The chloroplast are traveling along the outer perimeter to help move the vital nutrients thought the cells and convert them to substances used in the cell of the elodea cell. * What is the typical size difference between animal cells and bacterial cells? One of the main difference between an animal cell and a bacterial cell is a bacterial cell contains a plasmid‚ a ring of DNA‚ opposed
