what factors affect the rate of photosynthesis
Water Water is a very important raw material for photosynthesis. 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). These factors include: ⢠a) The supply of light to the leaf. nevertheless. Here a rise in light intensity has no affect on the rate of photosynthesis as the other factors such as temperature and carbon dioxide become limiting. most of the clip. Refer to Figure 1, the rate of photosynthesis increases linearly with increasing light intensity (from point A to point B on the graph). 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. Concentration. Decreases. The main factors affecting the rate of photosynthesis are light intensity, carbon dioxide concentration and temperature. SURVEY . 6 Answers. However, there are also a lot of factors that affect and derail the process of photosynthesis. 1. Factors affecting Photosynthesis Photosynthesis is affected by several external and internal factors. Photosynthesis is a chemical reaction that is fundamental to life. Favorite Answer. Carbon dioxide. Select all that apply. Effect of Temperature on the Rate of Photosynthesis. Q. If the amount of CO 2 increases up to 0.1%, the rate of photosynthesis also increases. Abstract: In this lab, four different types of leaves were tested to see the rate at which each leaf photosynthesized. Report an issue . If air infinites are infused with CO2. Relevance. This lab demonstrates how plants store light, capture light, and use light as energy for reproduction and growth, by photosynthesis. Repeat the count and calculate the mean rate of ⦠Stays the same. What Factors Affect the Rate of Photosynthesis in living leaves? The rate of photosynthesis could besides be measured by the sum of moles of CO2 that are consumed for every mole of sugar that is synthesized. light intensity pH temperature chlorophyll density water carbon dioxide soil nutrients 2 See answers tylermdons tylermdons chlorophyll density, water, carbon dioxide. External factors affecting Photosynthesis 1. Several factors can affect the rate of photosynthesis: light intensity carbon dioxide concentration temperature 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). This shows that the rate of photosynthesis is greater when higher concentrations of CO 2 are present. But, the rate of photosynthesis decreases, if the amount of CO 2 increases beyond 0.1%. BACKGROUND Photosynthesis fuels ecosystems and replenishes the Earthâs atmosphere with oxygen. Limiting factors The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature. Photosynthesis is a chemical reaction that is fundamental to life. There are several factors that affect the rate of photosynthesis. However, the rate declines after the temperature reaches an optimal level (usually around 35 C). 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). The rate of photosynthesis increases as the temperature increases. Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as ⦠Photosynthesis is a mechanism that is crucial to the survival of plants. Temperature. Name: Factors that affect the rate of Photosynthesis Directions: Read through the passage. Answer Save. ex: temp? 2. I'm having trouble answering my bio homework. Temperature, light intensity, carbon dioxide levels, water, oxygen and chlorophyll. There are many factors affecting photosynthesis, predominantly environmental conditions. answer choices . Anonymous. The rate of photosynthesis is affected by light intensity, temperature, carbon dioxide concentrations, and chlorophyll. Light intensity, water, soil pH, carbon dioxide concentration, temperature and other climatic conditions are the main factors affecting the rate of photosynthesis. Factor Affecting Photosynthesis Light. 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. Well, so explanation of the 6 factors that affect photosynthesis. Increases. In this video we are going to have a look at the factors that affect the rate of photosynthesis. The factors that affect the rate of photosynthesis are: 1. Factors affecting Photosynthesis DRAFT. b) The amount, and turn-over rate, of enzymes involved in the "dark reactions" of photosynthesis. 16. 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. 0 0. leticia. Click to see full answer. d Change one factor that may affect the rate of photosynthesis, keeping all other factors the same as far as possible. 4. Which factors affect the rate of photosynthesis? Furthermore, what are three factors that affect the rate at which photosynthesis occurs quizlet? All green plants are autotrophic. Temperature, light intensity, carbon dioxide levels, water, oxygen and chlorophyll. It is one of the major factors affecting photosynthesis. All of these factors interact to either increase or decrease the rate of photosynthesis, and changes in any one of them can seriously affect the process. Photosynthesis and its significance, mechanisms and the factors that Affecting it and its all Pigments are given below: DEFINITION OF PHOTOSYNTHESIS:. answer choices . Factors which affect the rate of photosynthesis when they are at a less than favourable level Leaf discs float in H2O. Light Intensity. 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. In any given situation one factor could affect the rate more than others. At this point increases in CO2 concentration do not cause increases in photosynthetic rate, so factors other than the supply of CO2 must be limiting the photosynthetic process. They can synthesise their own food. 2. However, the rate declines after the temperature reaches an optimal level (usually around 35 C). 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. Moreover, what are three factors that affect the rate at which photosynthesis occurs quizlet? 1 decade ago. (Refer to teaching notes.) Start studying What factors affect that rate of photosynthesis. Listed below are graphs for each factor and how they affect the rate of photosynthesis. 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. 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). What factors affect the rate of photosynthesis? There are 3 main factors: light intensity, carbon dioxide concentration and also temperature. 3. 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. 1.Carbon dioxide The amount of carbon dioxide in the atmosphere is 0.03%. Limiting factors The main factors affecting rate (process) of photosynthesis are light intensity, carbon dioxide concentration and temperature. PHOTOSYNTHESIS What factors affect the rate of photosynthesis in living leaves? 7 minutes ago. Tags: Question 5 . 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. Between 0oC and 25oC the rate of photosynthesis is approximately doubled for each 10oC rise in temperature. The rate of photosynthesis depends upon several factors they may be external or internal. Answer the follow-up questions that follow. All heterotrophs directly or indirectly depend upon green plants for food. the denseness of the discs will increase. 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. Provided other factors are not limiting, the rate of photosynthesis increases in direct proportion to the temperature. and light intensity, soil nutrients, and temperature. In many plants, the optimum temperature is 25oC. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Light Three characteristics of light (i) intensity (quantity) (ii) quality (wave length) and , (iii) duration significantly affect the rate of photosynthesis. 60 seconds .
