The effects of light intensity on rate of photosynthesis
Research Question: How will the change in light intensity (by changing the distance between the light source and the plant) affect the amount of bubbles produced by a marimo moss ball?
Background information:
Photosynthesis is the process where green plants use sunlight to produce water and carbon dioxide as the food and generates oxygen as a product.
〖6CO〗_2+〖6H〗_2 O → C_6 H_12 O_6+〖6O〗_2
There are three main factors that can change the rate of photosynthesis. When a plant is going through photosynthesis there are many steps in the reaction where each requires optimal conditions in order to maximize the activity. The factors that can slow the whole process of photosynthesis are called the limiting factors. These factors include light intensity, CO2 concentration, and temperature. In this experiment, the light intensity is being investigated on how this limiting factor can affect the rate of photosynthesis. In the process of photosynthesis, light is used in the light dependent reaction where it is needed for the photoactivation of electrons and the photolysis of water. Low light intensity will result in low production of photons. Therefore, there is less H^+ ions being pumped which results in the slower rate for photosynthesis. From the equation above, O_2 is a product from the process of photosynthesis. When there is a slower rate, there is less oxygen produced, thus the amount of bubbles floating through the
Photosynthesis is the conversion of light energy to chemical energy into sugars. It is the process in plants that uses carbon dioxide, water, and sunlight from its surroundings and releases oxygen as a byproduct (6H2O+6CO2+light energy -> C6H12O6+6O2). Photosynthesis is required for plants because they are autotrophs, organisms that make their own food. Plants require a specific environment that is ideal to them to be able to carry out the process. Environmental conditions can either increase or decrease the rate of photosynthesis. Things like colors of light, pH, and temperature can all affect the rate of photosynthesis in plants.
The effects of light intensity and light wavelength on photosynthesis was observed in two different experiments and closer study of different pigments in spinach was observed. For the experiment where the effects of light was observed, it was found that a light intensity of 30 cm, wavelengths of blue and red lights show the greatest photosynthetic activity. The different pigments present is spinach were also observed and it was noted that though chlorophyll is the most abundant in plants, there are other pigments present as well.
Photosynthesis is the process in which plants consumed inorganic materials like solar light, carbon dioxide and water and converted it to an organic molecule like sugar and an inorganic gas like oxygen. Light is one of the major elements influencing the rate of photosynthesis; direct light concentration affects the noncyclic pathway (light
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms ' activities. Plants need photosynthesis to survive. The balanced chemical equation for photosynthesis is 6 CO2 + 6 H2O ? C6H12O6 + 6 O2. In English terms, this equation translates to six carbon dioxide plus six
The purpose of this experiment was to investigate the effects of light intensity on the rate of photosynthesis in a Moneywort plant. By observing the plant in distilled water mixed with sodium bicarbonate, different light bulbs were targeted onto the plant. The measurement of the amount of bubbles present on the plant during the trial of the experiment enabled us to identify the comparisons between the activity of the light and the process of photosynthesis.
When using algae beads and a CO2 indicator, the process of Photosynthesis and Cellular Respiration can be measured. In this experiment the intensity of light will be altered in each trail, and the rate of Photosynthesis will then be measured. As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. However, once the light intensity gets high enough, the rate won’t increase anymore since there will be more-light than water and CO2; there will not be enough components from light, water, and CO2 to create the process of Photosynthesis. As CO2 dissolves and the amount of CO2 goes up, the pH will lower, which means the solutions color will change varying form red, orange and yellow, all pending on what the pH is at. CO2 will be produced from respiration, all while photosynthesis absorbs the CO2. This means that when the rate of photosynthesis is less than respiration, pH levels will decrease, and CO2 concentration will increase. Vis versa, when pH levels increase
The rate of photosynthesis can be determined different ways. Because oxygen is a product of photosynthesis and the Elodea plant is submerged in water, the oxygen is released in bubbles that rise to the surface of the water in the beaker. In this experiment, the rate of photosynthesis for each degree of light intensity can be measured by counting the number of bubbles released every 30 seconds for five minutes at each distance. The rate is the number of bubbles released per minute.
The light source will be kept at a constant distance of 5cm away from the water beaker
The intention of this experiment is to determine the effects of pH on the rate of photosynthesis in living leaves. Photosynthesis is a process by which plants convert light energy captured from the sun into chemical energy which they use to perform various plant functions. During the photosynthesis process, light, carbon dioxide, and water react to produce products: sugar and oxygen. The equation for photosynthesis is:
If you expose a photosynthesizing plant to water that contains both radioactive H and radioactive O, in which of the products of photosynthesis will the radioactive H and O show up?
Photosynthesis is essential to all living organism such as animals and plants. Photosynthesis is a process used by plants and other autotrophs to capture light energy and use it to power chemical reaction that converts carbon dioxide and water into oxygen, carbohydrates and water. (Textbook: Principles of Biology). The reactants and the products of photosynthesis are:
Photosynthesis is a reproductive system that occurs in plants. The main components required for photosynthesizing are sunlight, energy, water and mineral from soil, and carbon dioxide from the air. Once these components are combined they
Photosynthesis can be defined as the production of simple sugars from carbon dioxide and
Photosynthesis is an essential process for plants to prevent enthalpy, maintain metabolism and sustain to its environment. Photosynthesis allows plants to convert carbon dioxide to organic molecules using light as a source of energy. The key elements that are required for the process of photosynthesis are carbon dioxide, water, and light. All the components needed for photosynthesis are used in small quantities as they have adverse effects on the plant, for example, if there is too much carbon dioxide, the spores of the plant reduce in size thus affecting respiration and evaporating (Carnegie Institution, 2010).
Photosynthesis is a biochemical process in which plant, algae, and some bacteria harness the energy of light to produce food. Nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth¡¦s atmosphere. Factors that affect photosynthesis are light intensity and wave length, carbon dioxide concentration, and temperature.
