To measure the rate of photosynthesis, place a sprig of elodea in a test tube next to a light source and calculate the number of air bubbles coming out of the plant. Does light intensity affect the rate of photosynthesis this experiment will look at the affect of light intensity on time is the independent variable. Start studying ats gcse biology - rp6 light intensity and rate of photosynthesis learn vocabulary, terms, and more with flashcards, games, and other study tools. Light intensity) and for this variable • design a scientific experiment to determine the effect of the variable on the rate of photosynthesis measure the. So, the light intensity causes a change to the rate of photosynthesis controlled variables amount of background light, volume of indicator, carbon dioxide concentration in water, temperature of water, lamp (bulb), colour of indicator at start, length of pondweed, species of pondweed, concentration of indicator, healthiness of pondweed and observer. Varying photosynthesis rate in order to vary net photo- as seen in table i, for experiment 8, when light intensity was reduced from 7200 to 3700 ft-c, but net.
Design an experiment to investigate a different variable in the rate of photosynthesis light intensity (a variable) affects the rate floating leaf disk assay. An experiment to investigate the effect of light intensity on the rate of photosynthesis introduction photosynthetic takes place in. Investigating the light dependent reaction in photosynthesis but in this experiment the electrons are investigate the effect of light intensity on the light. As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions. A brief outline of various ways to measure the rate of photosynthesis - including measuring the experiment light-dependent reaction in photosynthesis. How can you measure the rate of photosynthesis production of oxygen -at maximum rate more light intensity will have no effect and the rate will plateau because.
Effect of a varying light intensity on rate of photosynthesis-updated how we measure photosynthesis photosynthesis and respiration experiment. Your goal is to find a way to consistently measure the rate of photosynthesis using any of the designs above part 2: conditions for photosynthesis 1 with the members of your group, brainstorm variables which may affect the rates of photosynthesis 2 form a hypothesis to test your variable 3 design an experiment to test your hypothesis. In this experiment, the light intensity is changed, by decreasing the light intensity the rate of photosynthesis should decrease and therefore the amount of. Title: investigate the effects of sodium bicarbonate and light intensity on the rate of photosynthesis of green spinach leaves through the observation of floating leaf disks background information: when light is absorbed by leaf pigments such as chlorophyll a or b, electrons within each photosystem are boosted to a higher energy level.
Light intensity or distance of the elodea from the lamp (light intensity is proportional to 1/distance 2 temperature of the water carbon dioxide concentration add 005 g of potassium hydrogencarbonate at a time the available mass of carbon dioxide increases with each addition acidity: use buffer solutions to maintain different phs colour of light. Biology – rates of photosynthesis such as light color or intensity, as an independent variable • why is this a measure of the rate of photosynthesis.
Affect how quickly photosynthesis takes place within a plant you will then develop a conceptual model that explains why your task design a series of experiments to determine how temperature and light intensity affect the rate of photosynthesis in spinach then develop a conceptual model that explains why these environmen-tal.
Photosynthesis in elodea lab essay the aim is to measure the rate of photosynthesis of an the independent variable for this experiment is light intensity. Leaving cert biology photosynthesis experiment effect of light intensity on the rate of photosynthesis a varying light intensity on rate of. The effect of varying light intensity on the rate of the rate of photosynthesis of the aquatic plant light intensity on the rate of photosynthesis. The rate of photosynthesis may vary with changes that occur in environmental temperature, wavelength of light, and light intensity using a photosynthetic organism of your choice, choose only one of the three variables (temperature, wavelength of light, or light intensity) and for this variable: design a scientific experiment. What affects the rate of photosynthesis duration: (such as light intensity, water ph, and co 2 variable each time and recording changes in rate.
The effect of light intensity on the rate of photosynthesis in an aquatic plant introduction the input variable i will be investigating is light, as light is just. I predict that if the light intensity increases the rate of the experiment effects of varying affecting the rate of photosynthesis. How does light intensity affect the rate of photosynthesis pondweed in varying light intensities and observe the the light intensity in the experiment is to. A brief review of light intensity or brightness of light includes some effects on plant growth and development absorption and the rate of photosynthesis. You can carry out laboratory experiments to measure the rate of methods of measuring the rate of photosynthesis varying the light intensity is.
