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. Factors which affect the rate of photosynthesis when they are at a less than favourable level. 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. Factors affecting photosynthesis the external factors would include the availability of sunlight, temperature, co2 concentration and water as a plant photosynthesises, all these factors will simultaneously affect its rate.
The intensity of light, concentration of carbon dioxide and temperature are the three main factors that affect photosynthesis they determine the rate at which photosynthesis occurs. 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. To investigate how different factors affect the rate of photosynthesis the variables that will be changed are different intensity of light and different molarities of sodium bicarbonate and then measuring the rate of reaction (photosynthetic rate.
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. Many external and internal factors affect the rate of photosynthesis the external or environmental factors at:a light intensity, carbon dioxide concentration and temperature the internal factor influencing the photosynthesis is chlorophyll content of the leaves and protoplasmic factors. 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. 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. Affect the rate of photosynthesis in plants — both physical variables and biotic variables likewise, students consider variables that might affect the floating disk procedure itself these variables are compiled and categorized to serve as a guide for student questions.
- investigating photosynthesis in canadian pondweed aim the aim of the investigation is find out what factors affect the rate of photosynthesis photosynthesis should not occur if one of the limiting factors is not present plan ==== the factors affecting photosynthesis are: light - this will affect photosynthesis because it is one of the. External factors affecting photosynthesis photosynthesis is influenced by two categories of factors - external or environmental and internal or plant factors according to the law of limiting factors, put forward by ffblackman in 1905, photosynthesis is limited by the most limiting factor. At this point, other factors such as light intensity, water and temperature become limiting factors light intensity the rate at of photosynthesis increases with an increase in light intensity up to a certain level. Factors affecting rate of photosynthesis the process of photosynthesis is affected by two types of factors namely: internal factors chlorophyll.
Factors affecting photosynthesis are either internal or external internal factors are 1 stomatal condition ( sunken stomata less photosynthesis) 2 amount of starch ( less starch more is rate of photosynthesis) external factors are 1 atmosphe. 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 series of enzyme-catalysed reactions enzymes have an optimum temperature or a temperature at which they work best, so this will also affect the rate of photosynthesis. 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. 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.
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. This means that the factor directly affects the rate of photosynthesis on its own, regardless of the level of the other factors the major limiting factors for photosynthesis are light intensity. The rate of photosynthesis is affected by a number of factors including light levels, temperature, availability of water, and availability of nutrients if the conditions that the plant needs are improved the rate of photosynthesis should increase.
The rate of photosynthesis increase as light intensity increases, because more electrons are exited in both photosynthesis however are some point all of the available electrons are excited, and the maximum rate or photosynthesis is reached. 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 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 very high intensity may, in fact, slow down the rate as it bleaches the.
