Repeat for a third minute c change a factor that might affect the rate of photosynthesis d leave for 2 minutes, then count the number of bubbles produced in one minute repeat for a second minute repeat for a third minute e change the factor to another value and repeat instruction d questions 1 what did you test. Photosynthesis is a process of food production of plants, algae and other photosynthetic organisms in such process, photosynthetic organisms known as photoautotroph aids in the purification of the atmosphere by converting carbon dioxide into organic compounds that they used as food and nutrients, eventually. There are a number of factors that interact to make the process of photosynthesis work any one of these could become a limiting factor 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. Photosynthesis is a chemical reaction that is fundamental to life in this video we are going to have a look at the factors that affect the rate of photosynt. 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 this topic is especially important to scientist and farmers by understanding the factors that affect the rate of. Using iron stress to reduce the total amount of light-harvesting and electron transport components per unit leaf area, the influence of light-harvesting and electron transport capacity on photosynthesis in sugar beet (beta vulgaris l cv f58-554h1) leaves was explored by monitoring net co2 exchange rate (p) in relation to.
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 this means that, at any given time, only one factors is the most limiting factor. 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 to adequately explain your result in your lab reports, you will need to discuss some of the factors that affect the rate of. A meta-analysis was then conducted to assess the ranges of photosynthetic pigment content calculated frequency distributions of pigments were compared with those expected from the theoretical pigment composition responses to environmental factors were also analysed the results revealed that.
Factors affecting the rate of photosynthesis 1 dathan c s factors affecting rate of photosynthesis 2 the process of photosynthesis is affected by two types of factors namely: 1external factors 2internal factors - 3 external factors a sunlight b temperature c carbon dioxide d water and e. The photosynthesis of cocoa (theobroma cacao linn) as influenced by light, temperature and vapour pressure deficit (vpd) was studied in the field net photosynthetic rate (pn), transpiration rate and stomatal conductance showed significant seasonal variations pn was highest during periods of low evaporative demand. Transpiration transpiration is the evaporation of water from plants it occurs chiefly at the leaves while their stomata are open for the passage of co2 and o2 during photosynthesis.
Limiting factors 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 directly affects the rate at which photosynthesis can take place masking the effects of the other. 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 chlorophyll normal. Often times, we simplistically think about light as the driver of photosynthesis and temperature as the key to control crop timing although that's generally true, other cultural and environmental factors influence photosynthesis and thus, crop growth and quality light provides the energy for photosynthetic pigments to convert. A secondary school revision resource for ocr gcse science about understanding our environment, photosynthesis and respiration.
The lesson deals with some of the major factors that are affecting photosynthesis these are broadly divided into internal and external factors some of the internal factors are dependent on the genetic composition and the growth of the plant the external factors would include the availability of sunlight, temperature, co2. What factor most affects the rate of photosynthesis the main variables which affect photosynthesis are light, water, co2 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 affect the rate of photosynthesis,. Electron transport components per unit leaf area, the influence of light- harvesting and electron transport capacity on photosynthesis in sugar beet (beta vudgaris l cv f58-554h1) leaves was explored by monitoring net co2 exchange rate (p) in relation to changes in the content of chl in most light/co2 environments, and.
