Photosynthesis is a process that is used by plants to harness suns energy to produce food. Plants have cells in the leaves that help trap energy from the sunlight. The light trapped from the sunlight is converted into other components that are used by the plant to make food. The energy used for photosynthesis comes from the photons absorbed by the plant leaves. The photons are reduced to other components by water.
This is because if the amount of light decreases, the amount of photosynthesis will also decrease. If the light increases, photosynthesis will also increase. Bubbles are oxygen, which are released during the light reaction of the plant during photosynthesis. In the first step of photosynthesis, the plants take the energy captured by sunlight by chlorophyll, then releasing oxygen as a byproduct. For plants, photosynthesis takes place in organelles called chloroplasts.
Light energy has a major role in this process. Without this energy, photosynthesis is not possible to occur. In this experiment, I will find out the correlation between light energy, rate of carbon dioxide, and rate of photosynthesis. I will place the beaker containing the plant in three different distances and measure the resulting bubbles oxygen produced. The number bubbles produced shows the affect of light energy to the rate of photosynthesis.
The primary photosynthetic pigment in plants is Chlorophyll a. Chlorophyll a molecules as well as chlorophyll b and the carotenoids capture light energy and transfer it to the single chlorophyll a molecule at the reaction center. The carotenoids are carotenes and xanthophylls, which will protect the photosynthetic system from the damaging effects of ultraviolet light. Hypothesis: The rate of photosynthesis in plant cells is mainly determined by the amount of light it receives and the temperature around it. The cuvette containing unboiled chloroplasts that have been exposed to light will have an increasingly
Photosynthesis and Cellular Respiration Abstract In order for plants to live, they must have an energy source. This energy source is achieved through two metabolic processes known as cellular respiration and photosynthesis. These two reactions can be affected by a series of environmental factors and in this lab pH levels are being experimented on in order to see the effects of pH on oxygen production in photosynthesis and oxygen consumption in cellular respiration. To conduct this experiment, an enclosed apparatus was used and a number of leaf disks were used to represent the reaction of photosynthesis and cellular respiration. Introduction All organisms and their individual cells need a source of energy and air supply in order to maintain life.
Photosynthesis and respiration are complete opposites, the only similarities is that they both produce energy. In photosynthesis the energy is produced when this reaction happens Sunlight Hydrogen + carbon dioxide Oxygen + Glucose 6CO2 + 6H2O C6H12O6 + 6O2 Glucose is made up of carbon, hydrogen and oxygen atoms. Glucose made by the process of photosynthesis may be used in three ways: 1. It can be converted into chemicals required for growth of plant cells such as cellulose 2. It can be converted into starch, a storage molecule, that can be converted back to glucose when the plant requires it 3.
During the day, carbon dioxide is released from the organic acids made the night before to become incorporated into sugar in the chloroplasts. C4 plants are plants that preface the Calvin cycle with reactions that incorporate carbon dioxide into a four-carbon compound, the end product which supplies carbon dioxide for the Calvin cycle. In C4 plants, there are two types of photosynthetic cells which are called bundle-sheath cells and mesophyll cells. In mesophyll cells, the enzyme PEP carboxylase adds carbon dioxide to PEP. A four-carbon compound conveys the atoms of the carbon dioxide into a bundle-sheath by way of plasmodesmata.
Effect of light intensity on photosynthesis Planning What was the aim of your experiment? To find the effect of light intensity on the rate of photosynthesis. Draw a labelled diagram of the equipment you need What did you measure? The colour of the indicator which tells us the amount of carbon dioxide used by the plant. Describe how you carried out your investigation?
Introduction: Photosynthesis is one of the most important processes for organisms to live, and it is a process that essentially absorbs light energy from the sun and turns it into chemical energy. Sunlight 6 CO2 + 6 H2O C6H12O6 + 6 O2 Carbon Water Glucose oxygen Dioxide Question: How does light intensity play a role in affecting the rate of photosynthesis in Elodea plants? Aim: The aim of my experiment is to see how much of a role light takes in the process of photosynthesis. In the sense of what sort of spectrum there is in terms of the ability of the Elodea plant to continue to photosynthesize with “too little” or “too much” light. I will do this by counting the number of bubbles that are released, as they are a product of the process of photosynthesis.
Trees need food, just like any other living species. The difference is that trees make their own food by the process called photosynthesis. Photosynthesis is the process in which light energy is converted into chemical energy. Sunlight, carbon dioxide, and water are what is needed for plants to make their own food. The roots absorb the water and leaves from the plant absorb carbon dioxide.
