Photosynthesis What is Photosynthesis? That is the question. For billions of years the human race has gone through their lives not knowing the importance and impact that photosynthesis has on them. However, my research and many scientists research into Photosynthesis has brought to light what many have shoved to the dark. What is Photosynthesis exactly? Well the simplified version that we’ve all been told when we’re young is that it is something that plants do that changes carbon dioxide into oxygen so we can breath. While partially true there is still so much that is missing. Photosynthesis is the process of plants absorbing light energy from the sun into those chloroplasts and converting it into chemical energy, or sugar. Plants use the energy from the sunlight they absorb to convert the carbon dioxide from the air and water from the soil into glucose (sugar) and H2O (oxygen). Most of the cool stuff with the chloroplasts happens mainly in the leaves of plants. Simply put the carbon dioxide that the plants need for the chemical reaction are absorbed by stomata in the …show more content…
His experiment went a like this: Ingenhousz submerged one plants roots underwater in the sunlight and another submerged plants roots in the shade. The experiment showed that the plant in the sunlight would have air bubbles released from the roots of the plant into the water while the plant in the shade would have no bubbles. This showed Ingenhousz that plants use light to produce oxygen. My explanation however is gravely understating the entire scope of time and intellect needed to discover something like Photosynthesis. Ingenhousz thought the same thing because it took him years to perfect his theory on photosynthesis, 9 years to be exact. Why spend all that time on one little theory though? What is so important about Photosynthesis
Photosynthesis consists of the following equation: Sun light Carbon dioxide + Water = = == == ==> Glucose + Oxygen Chlorophyll Chlorophyll is a substance found in chloroplasts, found in the cells of leaves.
The Effect of Light Intensity on the Rate of Oxygen Production in a Plant While Photosynthesis is Taking Place
= > [CH2O} + O2 + H2O, This shows that when the light intensity is increased the rate of reaction will be more quicker he only anomalous result there was, is the one in the 100 watt result the reading after 5 minutes is anomalous because it does not follow the predicted pattern of increasing in the production of gas because it is lower I know from my own knowledge of photosynthesise that when the light intensity is increased the rate of reaction will be more quicker because many plants and trees photosynthesise quicker in stronger light and photosynthesise slower in dimly lit places. The chlorophyll absorbs light energy and enables it to be used by the plant for building up sugar. The overall effect is that energy is transferred from sunlight to sugar molecules.
Before learning about photosynthesis, I thought this was just a way for plants to grow, not knowing the full detail that goes on inside the plant for it to grow. So, after learning about what photosynthesis is and how it truly works, it is something that is remarkable and how plants are really the only living thing that uses this process. Photosynthesis is the process of taking in carbon dioxide (CO2), which is a gas that is exhaled from animals and goes into the air and is absorbed into a plant, water (H2O) which is absorbed through the roots of a plant or known as capillary action, sunlight is absorbed through chloroplasts which contain chlorophyll or better known as the leaves of the plant. With the photosynthesis process, the plant can create a by-product known as oxygen gas which is released through the little pores into the atmosphere (Simon, Dickey, Hogan & Reece, n.d.).
Moreover, a future experiment is to determine the effect that the distance between the lamp and the solution has on the rate of photosynthesis. Several experiments with a similar setup to this experiment that vary the distances between the lamp and solution could be used to test this.
The Prentice Gallery Chemistry book defines photosynthesis as, “The procedure by which green plants and algae use radiant power from the sun to fuse glucose from carbon dioxide and water.” The glory of discovering photosynthesis does not belong to any one scientist, but rather numerous scientists contributed to refining the concept we now know as photosynthesis. Before describing the process of photosynthesis, I will provide a brief description of several of the important events that led to its discovery.
Photosynthesis in simpler turns is the ability of a live plant to carry on its chemical process by the use of light energy. Photosynthesis can not take place when there is absolutely no light, instead it stores the light it captures during the day, and uses it when needed. Photosynthesis can take place in land plants and aquarian plants such as algae. There are many factors that influence the ability of a plant to go through photosynthesis, such as light, the color of light and amount of water and or light.
Photosynthesis is chemical process in which plants capture energy from the sun, through components called chlorophyll, and use carbon dioxide (CO2) and water (H2O) to then convert the sunlight into glucose (C6H12O6). The byproducts of the reaction are oxygen and water. Although it is mostly thought of as a chemical process, a lot
He showed light is essential to plant respiration and that the gas plants produce in light is oxygen. (3) This caused him to be the discoverer of photosynthesis. He was born in 1730 in what is now the southern Netherlands. When he was only sixteen he began his study of medicine at the University of Leuven. He received his MD in 1753. When he transferred himself to England he personally met Ben Franklin. Henry Cavendish, and Joseph Priestly. He soon traveled to Calne, A town in England. In the same laboratory his friend Joseph Priestly discovered oxygen, Ingenhousz carried out his research on photosynthesis.(3) In his experiment he placed plants under water in a clear container and noticed that their leaves made bubbles in sunlight. When he placed those plants in darkness the bubbles disappeared. He also noticed that the leaves and chlorophyll were where the gas was produced. He took the gas and tested it. The gas turned out to be oxygen. Also that in darkness it released carbon dioxide. The hypothesis was if he placed the plant in sunlight then he would see how it forms and what it does. The dependent variable was the plant and soil. The independent variables were sunlight and dark. He concluded that in the light plants produce oxygen and when in the dark plants produce carbon dioxide. This was the discovery of
Earth has experienced many eras with different climates. Earth’s climate continually cycles through ice age periods and interglacial periods, due to its orbit, the varying energy produced by the sun, and natural disasters like volcanic eruptions. According to the UXL Encyclopedia of Weather and Natural Disasters, the history of Earth’s forever changing climate is separated into six main time periods: the Hadean, Archaean, Proterozoic, Paleozoic, Mesozoic, and Cenozoic eras. The first three eras are combined into the more commonly known era, the Precambrian Era. The period began at the start of the Earth’s life, when it was just a ball of molten rock, to about 570 million years ago, where life began to sprout all over Earth’s surface.
Photosynthesis is a process in which plants and other organisms convert the light energy from the sun or any other source into chemical energy that can be released to fuel an organism’s activities. During this reaction, carbon dioxide and water are converted into glucose and oxygen. This process takes place in leaf cells which contain chloroplasts and the reaction requires light energy from the sun, which is absorbed by a green substance called chlorophyll. The plants absorb the water through their roots from the earth and carbon dioxide through their leaves.
Photosynthesis and cellular respiration help sustain life on planet earth as both are metabolic processes in their own way. Photosynthesis is the process by which plants and other organisms use energy from the sun to form glucose from water and carbon dioxide. From there, glucose is then converted to ATP by way of cellular respiration. To convert nutrients that are biochemical energy into ATP, a process such as cellular respiration that has reactions needs to take shape in the cell of an organism, releasing waste products at the same time. For the continuous energy cycle that tolerates life on Earth as we know it Photosynthesis and Cellular respiration very essential. They have a few stages where energy and various connections occur within the eukaryotic cell. Cellular respiration takes place in the lysosome, an organelle that is found in the cytoplasm of eukaryotic cells. It uses enzymes to break down biomolecules including proteins, nucleic acids, carbohydrates, and lipids. Photosynthesis involves the chloroplasts, which contain pigments that absorb the sunlight and then transfigure them to sugars the plant can use. Those specific processes are crucial in how far and diversified evolution has
According to scientists, photosynthesis is “the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.” ("pho•to•syn•the•sis,")
An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis. Introduction Photosynthetics take place in the chloroplasts of green plant cells. It can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [ IMAGE ] 6CO 2 + 6H20 C 6 H12 O 6 + 6O2 It has been proven many times that plants need light to be able to photosynthesize, so you can say that without light the plant would neither photosynthesize nor survive.
Photosynthesis is a cycle plants go through converting light into chemical energy for use later. Photosynthesis starts in the chloroplasts, they capture chlorophyll, an important chemical needed for photosynthesis. Chloroplasts also take water, carbon dioxide, oxygen and glucose. The chlorophyll is taken to the stroma, where carbon dioxide and water mix together to make
