Factor affecting photosynthesis
Factors affecting photosynthesis there are several ways of measuring the rate of photosynthesis in the lab these include: the rate of oxygen output. The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature in any given situation any one of these may become a limiting factor, in other words the factors that. What factor most affects the rate of photosynthesis the main variables which affect photosynthesis are light, water, co 2 concentration and temperature on a deeper level, other factors like amount of chlorophyll, availability of nutrients (eg mg is needed for chlorophyll synthesis) will also . What are some of the factors that affect photosynthesis in the photosynthesis investigation, you will compare the photosynthetic light response curve of your leaf to that studied by another group. 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.
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). Factors affecting photosynthesis: the term rate always involve time, so the rate of photosynthesis can be considered to be how fast photosynthesis takes place. Furthermore, the factors affecting photosynthesis can be separated loosely into two categories, being internal and external factors factors affecting internal factors include the structure of that particular plant, the age of the plant , the plant’s genetic make-up, growth, the orientation of leaves and so on.
In this video clip i will be looking at how temperature, light and carbon dioxide concentrations affect the rate of photo. Low light intensity lowers the rate of photosynthesis as the intensity is increased the rate also increases however, after reaching an intensity of 10,000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Learn factors affecting photosynthesis with free interactive flashcards choose from 500 different sets of factors affecting photosynthesis flashcards on quizlet. The following points highlight the fourteen main external and internal factors influencing photosynthesis the factors are: 1 carbon dioxide 2.
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. 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. The limiting factors which affect photosynthesis are: 1temperature - the rate of reaction increases with heat the molecules move about and come together faster photosynthesis also involves a . The rate of photosynthesis is affected by a number of factors including light levels, temperature, availability of water, and availability of nutrients. Photosynthesis is a process used by plants and other organisms to convert light there are three main factors affecting photosynthesis and several .
Factor affecting photosynthesis
Factors affecting photosynthesis temperature eppley (1972) light sverdrup’s critical depth model nutrients limitations uptake kinetics. 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 the control in this experiment was spinach, which was . Water is an essential factor in photosynthesis the effect of water can be understood by studying the yield of crops which is the direct result of photosynthetic activity it is found that even slight deficiency of water results in significant reduction in the crop yield.
In a process like photosynthesis which is affected by more than one factor, its rate is limited by the factor which is closest to its minimum value so at any point in time if one of the three factors is in low supply, this. Learn the factors of photosynthesis chemical process try these 4 simple tests to prove the requirement of light energy, water and others.
The purpose of this experiment is to observe the factors affecting the photosynthetic rate of leaves, which is measured in two ways firstly changing the light intensity, this will determine the rate of increase or decrease in photosynthesis. Factors affecting photosynthesis there are several factors that are required at an optimum level for a constant rate of photosynthesis light intensity: increased light intensity results in the high rate of photosynthesis and low light intensity would be considered as a low rate of photosynthesis. The factor that will effect photosynthesis the most is lightplants need light in order for photosynthesis to take place water,air, ph, and temperature will also effect photo synthesis.
