What factors affect the rate of photosynthesis? 2. There are 3 main factors: light intensity, carbon dioxide concentration and also temperature. most of the clip. What Factors Affect the Rate of Photosynthesis in living leaves? If the amount of CO 2 increases up to 0.1%, the rate of photosynthesis also increases. 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). Based on the equation, it's probably not surprising that carbon dioxide and sunlight are two major factors that affect photosynthesis, but there is a third that isn't so obvious: temperature. Answer the follow-up questions that follow. Concentration. Photosynthesis plays an important role in maintaining the natural balance of the environment by making sure that there is enough amount of oxygen in the atmosphere. But like I have stated above, this can be caused by other factors such as the difference in plants or anything I have not considered. e Leave for 2 minutes and then take counts of the number of bubbles produced in one minute. Explanation: Carbon Dioxide affect the rate in photosynthesis because it is used to make sugar in the photosynthesis reaction. MathsGee Answers, Africa’s largest free personalized study network that helps people find answers to problems and connect with experts for improved outcomes. BACKGROUND Photosynthesis fuels ecosystems and replenishes the Earth’s atmosphere with oxygen. These factors are called limiting factors. Carbon dioxide. However, the rate declines after the temperature reaches an optimal level (usually around 35 C). In many plants, the optimum temperature is 25oC. Between 0oC and 25oC the rate of photosynthesis is approximately doubled for each 10oC rise in temperature. what factors affect the rate of photosynthesis? 6 Answers. In this video we are going to have a look at the factors that affect the rate of photosynthesis. However, there are also a lot of factors that affect and derail the process of photosynthesis. Factors affecting Photosynthesis Photosynthesis is affected by several external and internal factors. PHOTOSYNTHESIS What factors affect the rate of photosynthesis in living leaves? The rate of photosynthesis depends upon several factors they may be external or internal. The rate of photosynthesis increases as the temperature increases. Photosynthesis is one of the most remarkable biochemical processes found on Earth and allows plants to use sunlight to make food from water and carbon dioxide. All heterotrophs directly or indirectly depend upon green plants for food. Additional factors to those already listed: Quality or color of light (such as plants under the canopy of taller plants), duration of the light (how long is the light available; long summer days versus short winter days), availability of mineral nutrients in the soil (N, P, K, Mg, Fe, Ca) needed to produce the molecules needed for photosynthesis. Like all enzyme-driven reactions, the rate of photosynthesis can be measured by either the disappearance of substrate or the accumulation of product (or by-products). Click to see full answer. Because photosynthesis determines the amount of food a plant can generate, the rate of photosynthesis determines the rate of growth of plants. Carbon Dioxide Concentration. 3. Anonymous. I'm having trouble answering my bio homework. 7 minutes ago. But, the rate of photosynthesis decreases, if the amount of CO 2 increases beyond 0.1%. ex: temp? Abstract: In this lab, four different types of leaves were tested to see the rate at which each leaf photosynthesized. temperature,humidity,light,wind, and atmospheric pressure.if u want details then ask so. Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as … Start studying What factors affect that rate of photosynthesis. These factors include: • a) The supply of light to the leaf. Temperature, light intensity, carbon dioxide levels, water, oxygen and chlorophyll. Limiting factors The main factors affecting rate (process) of photosynthesis are light intensity, carbon dioxide concentration and temperature. Several factors can affect the rate of photosynthesis: light intensity carbon dioxide concentration temperature 1.Carbon dioxide The amount of carbon dioxide in the atmosphere is 0.03%. What factors may affect the rate of photosynthesis? Light Three characteristics of light (i) intensity (quantity) (ii) quality (wave length) and , (iii) duration significantly affect the rate of photosynthesis. Photosynthesis is a chemical reaction that is fundamental to life. Well, so explanation of the 6 factors that affect photosynthesis. by s ... what happens to the rate of photosynthesis? SURVEY . Factor Affecting Photosynthesis Light. Factors which affect the rate of photosynthesis when they are at a less than favourable level Effect of Temperature on the Rate of Photosynthesis. 0 0. leticia. For example, the photosynthesis rate in 10% CO 2 was 0.3 mm/minute while it was 0.2 mm/minute in 5% CO 2. The rate of photosynthesis is affected by light intensity, temperature, carbon dioxide concentrations, and chlorophyll. Listed below are graphs for each factor and how they affect the rate of photosynthesis. Light intensity, water, soil pH, carbon dioxide concentration, temperature and other climatic conditions are the main factors affecting the rate of photosynthesis. Water Water is a very important raw material for photosynthesis. Select all that apply. Limiting factors The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature. 60 seconds . amount of water. b) The amount, and turn-over rate, of enzymes involved in the "dark reactions" of photosynthesis. In any given situation one factor could affect the rate more than others. Temperature. Relevance. Moreover, what are three factors that affect the rate at which photosynthesis occurs quizlet? Click to see full answer. There are several factors that affect the rate of photosynthesis. Answer Save. Photosynthesis is a chemical reaction that is fundamental to life. Leaf discs float in H2O. 4. light intensity pH temperature chlorophyll density water carbon dioxide soil nutrients 2 See answers tylermdons tylermdons chlorophyll density, water, carbon dioxide. Three main factors affect the rate of photosynthesis: Light intensity: Increasing light intensity will increase the rate of photosynthesis, until the maximum amount of light is being absorbed.The main photosynthetic pigment in green plants is chlorophyll, which absorbs red and blue wavelengths (explaining their green appearance). 16. Light Intensity. Stays the same. What factors influence the rate of photosynthesis ? All green plants are autotrophic. 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 factors. Some of the external factors are intensity and duration of sunlight, temperature, availability of CO 2, availability of water etc.Even though there are a number of different factors in a physiological process.The rate of the photosynthesis is determined by the limiting or smallest factor. There are many factors affecting photosynthesis, predominantly environmental conditions. Which factors affect the rate of photosynthesis? The factors that affect the rate of photosynthesis are: 1. Photosynthesis is a mechanism that is crucial to the survival of plants. Decreases. External factors. d Change one factor that may affect the rate of photosynthesis, keeping all other factors the same as far as possible. Tags: Question 5 . and light intensity, soil nutrients, and temperature. The main factors affecting the rate of photosynthesis are light intensity, carbon dioxide concentration and temperature. Provided other factors are not limiting, the rate of photosynthesis increases in direct proportion to the temperature. 1. Increases. The rate of photosynthesis increases as the temperature increases. Gradually the rate falls and at a certain light intensity, the rate of photosynthesis remain constant (from point B to point C on the graph).
