Effect of different concentrations of carbon dioxide on the rate of photosynthesis in spinach leafs

Measurements of photosynthesis and conductances the gas-exchange system described by delfine et al (1998) was used to determine leaf photosynthesis, respiration in the dark, and stomatal conductance all gas-exchange and fluorescence measurements used to calculate photosynthesis and conductances were taken on five different leaves for each treatment, at a leaf temperature of 25°c and a. The purpose of this lab is to happen out how different c dioxide concentrations affect the rate of photosynthesis in spinacia oleracea foliage hypothesis as the concentration of c dioxide is increased, the rate of photosynthesis is traveling to increase until it reaches a certain point from which the rate of photosynthesis will be changeless. High concentrations of bicarbonate decreased the photosynthetic assimilation of inorganic carbon in the two plant species to half that in the control plants on day 10 bicarbonate treatment did not cause any damage to the reaction centers of photosystem ii in morus alba it, however, caused a decline in the quantum efficiency of photosystem ii. Carbon dioxide and rate of photosynthesis an increase in the carbon dioxide generally increases until limited by another factor as it is normally present in the atmosphere at very low concentrations (about 004%), increasing carbon dioxide the graph below shows the effect of low carbon dioxide concentration it will.

Since the carbon dioxide is one of the raw materials that are needed for photosynthesis process, therefore the experiment aims to find out the affect of concentration carbon dioxide towards the rate of photosynthesis. Carbon dioxide is a waste merchandise of yeast respiration yeast is a living being hence optimum temperature is needed for activation of energy production the cellular respiration rate in barm can be affected by temperature. The aim of this lab is to find out how different carbon dioxide concentrations affect the rate of photosynthesis in spinach leafs hypothesis as the concentration of carbon dioxide is increased, the rate of photosynthesis is going to increase until it reaches a certain point from which the rate of photosynthesis will be constant. Photosynthetic rates at different carbon dioxide concentrations were also recorded in both the branches to calculate the carboxylation efficiency by generating co 2 response curves photosynthetic rate and stomatal conductance were higher in non-flowering branches as compared to the flowering ones, in both cultivars.

1 title: investigate the effects of sodium bicarbonate and light intensity on the rate of photosynthesis of green spinach leaves through the observation of floating leaf disks background information: when light is absorbed by leaf pigments such as chlorophyll a or b, electrons within each photosystem. However, at some point there's a limit that the rate of photosynthesis cannot increase above this is because it's limited by other factors, such as the level of carbon dioxide in the air it's interesting to note that the wavelength of the light also influences the rate of photosynthesis. Measuring the rate of photosynthesis carbon dioxide and water are formed, and the • bicarbonate, water, scale and graduated cylinder for students to make different concentrations of bicarbonate solutions • ruler to measure distance from light source.

Carbon dioxide: plants as described in the carbon dioxide: overview section of this module, plants use carbon dioxide (co 2) during photosynthesis--the process by which plants transform the sun's energy into a chemical form and create carbohydrate (c 6 h 12 o 6) moleculesplants use this chemical to grow. -at maximum rate more light intensity will have no effect and the rate will plateau because chlorophyll is saturated by light -different wave lengths have different affects on the rate how does the concentration of carbon dioxide affect the rate of photosynthesis. Hypothesis: if sodium bicarbonate is added to spinach leaves, then the rate of photosynthesis will increase since distilled water has no carbon dioxide present, photosynthesis will not be able to occur one of the reactants for photosynthesis is carbon dioxide, so without its presence, photosynthesis will not be able to happen. Photosynthesis is a highly regulated, multistep process it encompasses the harvest of solar energy, transfer of excitation energy, energy conversion, electron transfer from water to nadp +, atp generation and a series of enzymatic reactions that assimilate carbon dioxide and synthesize carbohydrate photosynthesis has a unique place in the history of plant science, as its central concepts. Abstract photosynthesis in plants is affected by the intensity of the light the plant is exposed to for this experiment, dcpip was added to cuvettes with spinach chloroplasts, which were exposed to an incandescent light at different distances for different intervals of time.

The temperature dependencies of the light-saturated rates of net photosynthesis at c a of 360 µl l −1 (a 360) were different depending on the growth temperature and on the duration at lt the temperature dependencies of the respiration rates were also different depending on the growth temperature ( fig 2 . Carbon dioxide amount, and determine the effects on the photosynthesis rate 5 prepare a graph of the collected data and analyze it materials needed: the amount of trapped light energy and the amount of carbon dioxide available affects the rate of photosynthesis. Carbon dioxide is present in the air we breathe, at very low concentrations even though it forms about 04% of the air, it is a needed factor in light-independent photosynthesis in higher concentrations, more carbon is incorporated into carbohydrate, therefore increasing the rate of photosynthesis in light-independent reactions. Lab 7 – photosynthesis introduction in order to survive, organisms require a source of energy and molecular building blocks from the environment such as carbon dioxide (co 2) and water (h 2 o), and using the from a plant with a green leaf (spinach) or one with a red leaf (coleus) using a hydrophobic ether-based solvent 93 exercise 2.

Effect of different concentrations of carbon dioxide on the rate of photosynthesis in spinach leafs

effect of different concentrations of carbon dioxide on the rate of photosynthesis in spinach leafs  Photosynthesis, carbon dioxide is synthesized into glucose using chemical bond energy stored in atp and the reducing power of nadph in eukaryotic autotrophs, both sets of reactions take place in a.

Three different ideas in regards to the photosynthesis of plants: the relation between light and starch production, the number and absorption wavelength preferences of the pigments involved in photosynthesis, and some possible assumptions that can be drawn from the correlation of the data. 1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis 2) photosynthesis requires carbon dioxide to furnish the carbon required to make glucose. The effects of oxygen concentration on photosynthesis and respiration in two hypersaline cyanobacterial mats were investigated experiments were carried out on mats from eilat, israel, with moderate photosynthetic activity, and mats from mallorca, spain, with high photosynthetic activity. The effects of varying concentrations of co on the rate of photosynthesis in spinach leaves introduction: future thoughts: could test multiple light wavelengths and see effects of different types of light discussion: hypothesis: if the amount of carbon dioxide is increased then the rate of photosynthesis will increase as well.

The reaction involves the fi xation of carbon dioxide this experiment uses the fl oating disk leaf assay to explore the process of photosynthesis in plants. The rate of photorespiration during photosynthesis and the relationship of the substrate of light respiration to the products of photosynthesis in sunflower leaves plant physiol 1971 dec 48 (6):712–719. Effects of photosynthetic photon flux and carbon dioxide concentration on the photosynthesis and growth of grafted pepper transplants during healing and acclimatization article full-text available.

Students conducted an experiment to determine the effect of light intensity on the rate of photosynthesis they punched 40 leaf disks from spinach leaves and used a syringe partially filled with water to pull the gases from the leaf disks so that all leaf disks sunk to the bottom of the syringe. • identify another variable that might affect photosynthesis and design an experiment that uses leaf disks to test your ideas • create hypotheses about the effects of environmental variables on the rate of photosynthesis. Effects of photosynthesis of spinach leaves in different light conditions introduction photosynthesis is the process of converting solar energy, carbon dioxide (co2), and water (h2o) into carbohydrates (ch2o) and oxygen (o2.
