Introduction Photosynthesis is a redox reaction which requires carbon dioxide‚ water and light to produce water and a 6-carbon sugar. The process of photosynthesis consists of two parts‚ a light reaction and a light-independent reaction. The method of changing light energy into chemical energy for the formation of NADPH and ATP is done through the light reactions. Light independent reactions use carbon dioxide and the products of light reactions (ATP and NADPH) to form compounds such as glucose

How do limiting factors affect the rate of photosynthesis? Rate is the measurement of an amount of product or time. In the case of the rate of photosynthesis‚ it is measuring the gain of mass or growth over time. If the plant is an aquatic one that grows in water the rate of photosynthesis can be measured by counting oxygen bubbles or the volume of gas produced in a measured time period. A limiting factor is something that is present in the environment that has a short supply and because of that

The Effect of Distance from Light Source on the Rate of Photosynthesis Introduction: The effect of distance from the light source on the rate of photosynthesis was tested in this experiment. This was tested to find ways to accelerate the rate of photosynthesis. If plants are placed closer to a source of light‚ then their rate of photosynthesis will be higher because they are receiving more light. Experimental Design: The independent variable is the distance of the beaker from the light source

The major stresses that agricultural plants face are drought stress‚ cold stress‚ heat stress‚ flooding stress‚ mineral deficiency stress‚ salinity stress‚ and aluminum toxicity stress. Part 2: Glycine Betaine 2a. Wild type means it is the phenotype of the typical form of a species as it occurs in nature. 2b. L1 is different from the wild type because it is a strain

A Study on Mangrove Ecosystems Ecosystems are very delicate mechanisms‚ and the mangroves are particularly fragile. Mangroves rely on a multifaceted interface comprising of their land position‚ rainfall hydrology‚ sedimentation‚ subsidence‚ sea level‚ storms‚ pest-predator relationships and many other biogeochemical and environmental factors. Any one of these interactions becoming skewed or unsettled can lead to a rapid decline in the numbers of the mangroves in any environment. A relatively simple

Man Made Ecosystem By: De Belen‚ Bea Dela Cruz‚ Haydee Dofredo‚ Alona Jane What is Ecosystem? An ecosystem includes all of the living things (plants‚ animals and organisms) in a given area‚ interacting with each other‚ and also with their non-living environments (weather‚ earth‚ sun‚ soil‚ climate‚ atmosphere). Importance of Ecosystem. Ecosystems are communities of living things and the environmental features that support them. Ecosystems are essential to human life‚ providing us with innumerable

rate of photosynthesis until optimal levels are reached‚ then plateauing of results will occur. The hypothesis was refuted by evidence shown in the results (table two) as 0.5% concentration produced the greatest rate of photosynthesis‚ 3.10x10-3. Concentrations of 5% and 10% were deemed unusable as the agapanthus discs would not submerge‚ therefore the results did not enable a range of data. The results of the data indicate that 0.5% NaHCO3 is optimal in determining the rate of photosynthesis‚ 3.10x10-3
