dioxide concentration on the rate of photosynthesis Introduction Photosynthesis is a process that is essential for every living organism. Organic substances‚ such as glucose‚ are made from carbon dioxide and water by light energy from the sun. The light energy is absorbed by chlorophyll and converted to chemical energy. During the process‚ oxygen is released as a by-product. The rate of photosynthesis is affected by a few of factors‚ including light intensity‚ temperature‚ availability of

Hypothesis (Null): There will be no effect upon different distance intensities of light on the terrestrial isopods. IV: The different distance intensities of light at specified lengths (1 meter‚ 2 meter‚ and 3 meters) DV: The number of terrestrial isopods (rolypolies) on the unlighted side on the petri dish. Control: The unlighted side of the opened up petri dish. Purpose: To determine the light sensitivity of terrestrial isopods (rolypolies) in different levels of lighted environment. Number

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

The data found in this experiment supported the initial statement in the hypothesis‚ that blue would have the highest rate of photosynthesis (see Figure 7). The second part of the prediction was refuted by the data‚ as green had a higher rate than both yellow and red. This result seems to go against the experiment‚ however the answer is in Figure 5. When adding green food coloring to the solution (see Methods) dilution also took place. When comparing the wavelength of 540 nm (see Tables 1 & 2) with

Investigations in Light Intensity Change through Angular Displacement Guiding Question How does the intensity of light change as the angle of incidence to the light source increases? Prediction of Results Predict what you think will happen and what type of equation and graph might best fit the data representing the intensity of a light as the angle of incidence increases. Objective After completing this lesson‚ a student should be able to analyze light intensity striking a surface at varying

energy in food originally came from ATP. False pulling together 12. The term photosynthesis means “pulling apart with light” in Greek. True__ 13. The energy of sunlight is stored in the chemical bonds of carbohydrates. 14. Complete the table comparing two types of organisms. Autotrophs and Heterotrophs Type Description Examples Autotrophs An organism that is able to create its own food through photosynthesis (simple organic substances) Plants Heterotrophs An organism that “feeds”

Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around

the rate of photosynthesis using leaf discs. Aim : To measure the effect of light intensity on the rate of photosynthesis in leaf discs. Introduction : The simple concept of photosynthesis is that it can occurs in the presence of light‚ which takes place in the chloroplasts of green plant cells. Photosynthesis can also be defined as the production of simple sugars from carbon dioxide and water causing the release of glucose and oxygen. The chemical equation for photosynthesis can

The effect of differing wavelengths of visible light on the photosynthetic activity of Beta vulgaris Introduction Photosynthesis is a crucial biological process that occurs within the chloroplasts of plant cells where CO2 + H2O + Sunlight C6H12O6 + O2. The chloroplasts use light‚ an electromagnetic energy source‚ to produce food for the plant in the form of sugar molecules. During photosynthesis‚ the excited electrons from the light pass through proteins in the electron transport chain (ETC)‚ where

How do limiting factors affect the rate of photosynthesis? Rate is the measurement of an amount of product or time. In the case of the rate of photosynthesis‚ it is measuring the gain of mass or growth over time. If the plant is an aquatic one that grows in water the rate of photosynthesis can be measured by counting oxygen bubbles or the volume of gas produced in a measured time period. A limiting factor is something that is present in the environment that has a short supply and because of that
