Investigation in to the factors that affects the rate of fermentation of glucose aim: to investigate the factors that affects the rate of fermentation of glucose background knowledge enzymes fermentation is a form of an anaerobic respiration where by glucose is partially broken down so only a small amount of energy is released. Using the lab proposal that students wrote yesterday, students will conduct an experiment to determine the effects of colored light on the rate of photosynthesis after conducting the lab, students will input data into loggerpro. The rate at which they floated was a measure of how fast photosynthesis occurs the variable tested by the group was co2 concentration the results from our experiment showed that the amount of co2 in the environment of the spinach had an effect on the rate of photosynthesis. Investigating the effect of light intensity on the rate of photosynthesis by measuring co2 depletion.
This activity will allow students to measure the rate at which the photosynthesis process occurs students will work in small groups to design an experiment with one independent variable and test this variable on spinach leaf disks. When investigating the influence of light intensity on the rate of photosynthesis you must appreciate the inverse square law applied to light intensity for a fixed lamp power and light emission as you move the lamp further away, the light intensity falls, and so should the rate of photosynthesis. Investigation on how light intensity affects the rate of photosynthesis essay sample introduction: photosynthesis is the process by which green plants use the light energy to convert carbon dioxide and water into simple sugar called glucose, which provides a basic energy source for the plant. The rate of photosynthesis can be measured by: 1) measuring o2 production 2) measuring co2 consumption leaf structure and function in this investigation, you will use a system that measures the accumulation of oxygen in the leaf.
This is the rate of photosynthesis at that particular concentration of co 2 the gas should be checked to prove that it is indeed oxygen - relights a glowing splint repeat at different lower co 2 concentrations by using different dilutions of a saturated solution. Looking at limiting factors of photosynthesis and investigating light intensity aqa resources presentation- rate of photosynthesis activity docx, 23 kb. During the photosynthesis, the light intensity will increase when the rate of photosynthesis increase(pang 2006) in my result, the distances from light intensity are increased when the rate of photosynthesis decreases, which mean when the light intensity decrease, the rate of photosynthesis also decreases. The rate of photosynthesis increases linearly with increasing light intensity (from point a to b on the graph) gradually the rate falls of and at a certain light intensity the rate of photosynthesis stay constant (from point b to c on the graph.
Plan i plan to investigate how light intensity affects the rate of photosynthesis in pondweed the rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis. Guided inquiry activity in which the students will indirectly measure the rate of photosynthesis under specific environmental conditions using the floating disc assay students will also study the structure. This experiment will look at the affect of light intensity on the rate of photosynthesis on elodea plants the rate of photosynthesis is determined by the number of bubbles formed by the elodea plants. Bond, as it is in photosynthesis or (3) it may be re-emitted almost instantaneously as light energy of longer wavelength, a phenomenon known as fluorescence (when it is re-emitted as light at a later time, it.
photosynthesis and cellular respiration nina r mccray may 5, 2015 biology lab (scie207-1502-a-07) ladonna mccowan-ferrier photosynthesis and cellular respiration lab report introduction this is an investigation of the effect of the intensity of light (photosynthesis) have on the rate of cellular respiration (measured as the number of. A study of the effect of light intensity on the photosynthesis of hydrilla verticellata sprigs and the separation of photosynthesis pigments by paper chromatography. This is the rate of photosynthesis at that particular concentration of co2 the gas should be checked to prove that it is indeed oxygen - relights a glowing splint repeat at different lower co2 concentrations by using different dilutions of a saturated solution.
Investigating photosynthesis using immobilised algae class practical this procedure offers a method for measuring the rate of photosynthesis which depends directly. The rate of photosynthesis is affected by a number of factors including light levels, temperature, availability of water, and availability of nutrients. // provide alternate content for browsers that do not support scripting // or for those that have scripting disabled this virtual experiments require adobe flash.
Photosynthesis photosynthesis is a process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight photosynthesis occurs in plants, algae, and many species of bacteria. Investigating factors affecting the rate of photosynthesis see more biology lessons ap biology teaching biology science - biology science education life science science lessons science activities cell biology teaching activities school baccalaureate biology classroom interactive notebooks veggies science classroom. Photosynthesis and cellular respiration are great examples of energy-transforming systems, and they deﬁ ne the two ways in which organisms derive the energy they need to survive autotrophs (also called primary producers) capture free energy from the environment. To investigate the effects of light on the rate of photosynthesis hypothesis: read the entire investigation then work with your partner to develop a hypothesis for.
