The intensity of light, concentration of carbon dioxide andtemperature are the three main factors that affect photosynthesisthey determine the rate at which photosynthesis occurs. The main variables which affect photosynthesis are light, co2 concentration and temperature (1) photosynthesis is light dependent at low light intensities, this may become the limiting factor - one reason why plants grow better outdoors, rather than in the house, and one reason why we recommend the use o. Learning objectives: 1) to design and conduct an experiment to explore factors that affect photosynthesis 2) to connect and apply concepts, including the relationship between cell structure and function, strategies for capture and stores of energy, and the diffusion of gases across membranes. Factors affecting the rate of photosynthesis by introducing various modern conveniences in our society we are slowly changing our global ecosystem.
Nuffield foundation » teachers » practical biology » energy » photosynthesis » investigating factors affecting the rate of photosynthesis practical biology a collection of experiments that demonstrate biological concepts and processes. In an experiment, which is investigating the affect of an abiotic factor on photosynthesis, all the biotic factors like the type of the plant should be kept same samples from the aquatic plant e canadensis will be used for each experiment. What factors affect the rate of photosynthesis in living leaves abstract: in this lab, four different types of leaves were tested to see the rate at which each leaf photosynthesized this lab demonstrates how plants store light, capture light, and use light as energy for reproduction and growth, by photosynthesis. Factors affecting photosynthesis temperature eppley (1972) light sverdrup's critical depth model nutrients limitations uptake kinetics.
By understanding the factors that affect the rate of photosynthesis they can do work to try and increase the rate of photosynthesis to increase the yield of a crop the three main things affecting the rate of photosynthesis are. Factors of photosynthesis process by 4 scientific tests september 9, 2014 by shyam chathuranga 3 comments photosynthesis is the process of turning light energy obtained from sun to glucose - foods - and oxygen gas. Aerobic cellular respiration rates vary according to three main factors: the amount of nutrients available to the cell, the specific type of cell and the ambient temperature all three factors affect the rate at which respiration takes place, according to uc clermont college aerobic cellular. This resource uses the example of a tropical fish tank to illustrate how the factors that affect photosynthesis (light co2 and heat) can be optimised to good effect ideal if supported in class with a real-life fish tank but can be used in its own right.
Factors that interact and simultaneously affect photosynthesis within the chloroplast there is the membranous system consisting of grana the stoma lamellae and the fluid stoma as shown in figure there is a clear division of labor within the chloroplast the membrane system is responsible for. The rate of photosynthesis depends upon several factors they may be external or internal some of the external factors are intensity and duration of sunlight, temperature, availability of co 2, availability of water etc. Will be guided toward ecological factors that might affect the 3 input components of photosynthesis: sunlight, water & carbon dioxide teachers will then transition into the lab by discussing how we can test.
There are a variety of algae species occurring in different habitats in the world such as fresh water, marine, desert sand and snow these photosynthetic organisms are vital since aquatic animals feed on the organic matter they produce. According to the law of limiting factors, put forward by ffblackman in 1905, photosynthesis is limited by the most limiting factor this means that, at any given time, only one factors is the most limiting factor among all and this factor determines the rate of photosynthesis. 1 extensive measurements have been obtained (a) relating photosynthesis and light intensity for a large range of co 2 concentrations and (b) relating photosynthesis and co 2 at different light intensities.
Photosynthesis is a process by which plants prepare their own food in the presence of water, chlorophyll, sunlight, and co2 there are several factors affecting photosynthesis- its rate and efficiency. Factors affecting photosynthesis can be divided into two broad categories - the internal and external (environmental) factors internal factors 1 chlorophyll the amount of chlorophyll present has a direct relationship with the rate of photosynthesis because this pigment is directly involved in trapping light energy responsible for the light reactions. The environmental factors affecting the process of photosynthesis follow the law of limiting factor as hypothesized by the british plant physiologist f f blackman in 1905 according to this hypothesis, when a process is influenced by a number of factors, the rate of the process is limited by the.
Photosynthesis is the process by which higher plants manufacture dry matter through the aid of chlorophyll pigment, which uses solar energy to produce carbohydrates out of water and carbon dioxide the overall efficiency of this critical process is somewhat low, and its mechanics are. Factors affecting the rate of photosynthesis the term rate always involves time, so the rate of photosynthesis can be considered to be how fast photosynthesis takes place this can be measured by the amount of glucose produced by a plant over a given time. Affect of light intensity on rate of photosynthesis 2 4 6 8 ph 11 11 115 12 table2 shows the ph taken from beaker b, which was at 40 cm distance from the lamp at the time interval 2, 4, 6 and 8 minutes. Cellular energetics activity #5 page 2 experiment #1: effect of light intensity on the rate of photosynthesis what effect does light intensity have on the rate of photosynthesis in tomato (c -3.
