Photosynthesis Limiting Factor

Improved Essays
In this assignment I am going to identify the factors which can limit the rate of photosynthesis. There are three main limiting factors to identify these are:

•Light intensity

•Carbon dioxide concentration

•Temperature

The photosynthesis process uses more than one factor to achieve maximum capability. " Its rate is limited by the factor which is closest to it minimum value" Pass My Exams. Factors affecting the rate of photosynthesis. Available: http://www.passmyexams.co.uk/GCSE/biology/factors/factors-affecting-rate-of-photosynthesis.html. Last accessed 04/12/2015.

In processes like photosynthesis all the factors that affects its rate all need to work together. The rate of the process at one point does not affect all the factors, but by the factors that have the best levels at the time. This is called limiting factors as it limits the rate the process can take

These plants only receive sunflecks, but it is believed that these provide up to 60% of the daily carbon gain by seedlings like Euphorbia forbesii and Claoxylon sandwicense.

For photosynthesis to be at its optimum there should be on average of 16 hours of sunlight and 8 hours of darkness.

The main energy for photosynthesis comes from the light from the sun, this comes from the exothermic reactions that occurs on the sun. The energy of lights travels in wave motion, which contain photon particles. The wavelength force can be seen in the size of the wavelength produced. The bigger the wavelength the lesser energy it is carrying.

Fig1 shows an electromagnetic spectrum (the range of different types of radiation). Most of the radiation that hit the earth from the sun is about 400-700nm wavelengths, our eyes have evolved to these levels. 400-700nm is known as the visible spectrum. We perceive white light but this is divided up in to the familiar seven

    Light intensity was directly proportional to electron transport. As light intensity increased so did mean change in absorbance. The highest and lowest light intensities also had the highest and lowest mean change in absorbance. The more light that is readily available is a key factor in photosynthesis and electron transport. More light means more light energy which helps split water molecules at the beginning of electron transport.…

    This process is carried out in chlorophyll, a green pigment present in plants, some bacteria and some prostists4. Photosynthesis occurs in two stages, a light-dependent process (light reactions) and a light-independent process (dark reactions). During the light reactions, electrons in chlorophyll a are excited to a higher energy state by sunlight. The energy from the sunlight is converted to ATP and NADH, water is split releasing oxygen as a by-product and the ATP and NADH are used during the dark reaction to make C-C bonds4. During the light-dependent process, an important metabolic pathway occurs known as photophosphorylation occurs whereby energy is converted from a light-excited electron into the pyrophosphate bond of an ADP molecule4.…

    The light source in the classroom was insufficient, photosynthesis requires an abundance of light in order to occur quickly and efficiently. The light intensity of the classroom did allow for photosynthesis to take place. When the beakers were moved in front of a very bright light, reactions began to happen. The time would have been much shorter for photosynthesis to occur in beaker one, if the classroom lighting was more intense and bright.…

    The rate at which photosynthesis occurs needs to be higher because photosynthesis creates building blocks for growth. (six-carbon simple sugars) Cellular respiration is also needed for the growth, but first it needs to break down the simple sugars to create and distribute the energy. 3.a. More light should increase the rate of photosynthesis…

    This photosynthetic process involves two separate stages: the light cycle in which the plant converts light energy into chemical energy and secondly, the Calvin cycle which uses that chemical energy to make sugars for food. To perform these processes, plants use organelles called chloroplasts that absorbs light to fuel the plant. These chloroplasts are consisted of different pigments that absorb specific wavelengths of light, with the two most abundant being chlorophyll a and chlorophyll b. This lab consists of two different experiments that relate to the photosynthetic processes in plants. The objective of the first experiment is to demonstrate the presence of various different pigments in a vegetable leaf using paper chromatography and identify them by using their rate of movement(Rf) and their colors.…

If our bodied could not get the need amounts of energy and carbohydrates our organs and vital functions would not have the ability to complete needed processes for life. The purpose of this lab was to see the different changes light color has no the rate of photosynthesis through light intensity and wavelengths absorbed.

    The two stages of photosynthesis are the light reactions that occur in the former and the light-independent or “synthesis” reactions occurring in the latter (Stegenga, 2015). The absorption of solar energy or light occurs in the light reactions, while the “synthesis” reactions leads to formation of carbohydrates from carbon dioxide in a process known as the Calvin cycle (Stegenga, 2015). This experiment of determining the rate of photosynthesis in the chloroplasts of spinach leaves utilizes the findings of the Hill…

    In this experiment, the shorter the distance between the leaf discs and the light source, the higher the light intensity, thus the higher the rate of photosynthesis in the leaf discs. The theory of Photosynthesis is that it can occur in high or low light intensity. At low light intensity, where the distance is far, there will be a shortage of the product of light independent reactions. The products which decreased are NADPH2 and ATP energy. As the distance becomes shorter, meaning the light intensity increases , more products will be produced.…

    Photosynthesis is a plant’s mechanism of converting sunlight and CO2 into energy in the form of organic material (Hohmann-Marriott and Blankenship 2011). Plant respiration is the process of using energy and oxygen to produce CO2 (Gonzalez-Meler et al. 2004). Almost all plants reproduce and respire, therefore it is important to know what factors could affect the rate of photosynthesis and respiration to better understand how plants function. Some research has shown that elevated CO2 concentrations may determine plant productivity by affecting plant physiological processes, and ecosystem structure and functions such as photosynthesis ( Xu et al. 1987).…
