Photosynthesis Essays

Introduction: Photosynthesis is a process used by plants and specific types of bacteria in order to make their own food source from sunlight to chemical energy. It is mainly occurred within the leaves of the plant. The reaction requires light energy in order for it to be absorbed by chlorophyll. During the reaction carbon dioxide, water is converted into glucose and oxygen as shown below: Figure 1 (photosynthesis uses light energy to convert carbon dioxide into a carbohydrate) (The Chemical

Introduction: What is photosynthesis? The chemical progress of photosynthesis is when a green plant and sometimes other organisms produce O2 (oxygen) by using the light energy from the sun, CO2 (carbon dioxide) and water. The green colour pigment is created by chlorophyll in the plant. 6 CO2 + 6 H2O –> C6H12O6 + 6O2 Carbon dioxide + Water –> Glucose + Oxygen Research question: How does the rate of photosynthesis change in Cabomba pond weed when the changing variable is the light intensity

“Photosynthesis is the most important reaction on Earth. “ –unknown (Brainy quotes). photosynthesis is a chemical process in which plants and other organisms use sunlight to synthesise nutrients from water and carbon dioxide. (source 1) Photosynthesis includes a significant scientific background behind it. The process takes place in chloroplasts, which is a type of plant cell organelle frequently referred to a plastid. They are recognised to be eukaryotic cell structures. The chloroplast a green

________________________________________ Abstract: The process of photosynthesis is the most essential chemical processes that occurs on the planet. Most terrestrial organisms require oxygen to survive and much of the oxygen in the atmosphere is produced by photosynthesis. Plants are the organisms that carry out this chemical reaction and so it is crucial to understand what impacts this process in both terrestrial and aquatic environments. This experiment considers the photosynthesis of aquatic plants and how various concentrations

Purpose: The purpose of this experiment is to see how long it takes for the 10 spinach leaf discs to undergo photosynthesis and thereby rise in the two solutions. Hypothesis: All of the leaf discs in the sodium bicarbonate solution should be floating before the discs in plain water because the bicarbonate is a carbon source that will allow photosynthesis to continue. Background: Light is absorbed by leaf pigments (chlorophyll) which makes electrons within a photosystem moved to a higher energy

A. Were the seeds in the “N” tube undergoing both photosynthesis and respiration, only photosynthesis, or only respiration? Use your results in Data Table 2 to support your answer. The seeds in test tube "N" underwent respiration. Respiration is always happening. As stated in the background of the lab, "seeds are considered to be in a period of dormancy, where they metabolize stored energy at a very slow rate while the seed is still considered alive" (Hands On Labs). During germination, the developing

Advanced Biology Photosynthesis Lab Report By Cheryl G11 Introduction & Background Photosynthesis is the process by which light energy is converted to chemical energy. It occurs within each chloroplast in most of the green plants, and Carbon dioxide is one of the main components of this process. Plants use photosynthesis to produce their own food (glucose), some water and the oxygen that we need. The overall balanced equation is: 12 H2O+ 6 CO2 → 6 H2O+ C6H12O6 + 6 O2

Title Which frequencies and type of light aided and affected the efficiency of photosynthesis or carbon dioxide consumption in a spinach leaf? Purpose The purpose of the experiment/lab was to observe the effectiveness of different lights during the process of photosynthesis. Background Photosynthesis is a biological process. It occurs in plants, algae and specified bacteria (prokaryotes). Photosynthesis is the process where plants, algae, and bacteria convert light energy into chemical energy.

sodium bicarbonate concentrations on the rate of photosynthesis in spinach (Spinacia oleracea). Photosynthesis is the process by which plants and other photoautotrophs synthesize organic compounds from carbon dioxide (Faculty of Science and Horticulture, 2018). Photosynthesis takes place in the chloroplast of a plant cell, where sunlight, water, and carbon dioxide are used in a reaction to produce oxygen and sugar (Reese 2017). In the photosynthesis reaction carbon dioxide is reduced to make sugar

the two main contributing factors to photosynthesis rate. So in theory as temperature increases and light increases so will the photosynthesis rate. This is because reactions occur when the plant enzymes collide and bind with a substrate. The increase in temperature would mean an increase in the kinetic energy of the plant enzymes meaning they would move faster, and therefore collide more frequently with the substrates, so as a result an increase of photosynthesis occurs. However when a system reaches

the effect of light intensity on the rate of photosynthesis. Hypothesis Light intensity is directly proportional to the rate of photosynthesis. When the light isn’t intense, not many oxygen bubbles will be produced and thus observed. This indicates that the plant will not have enough derived energy from the sun to activate photosynthesis. Whereas, when the light intensity is great, the rate of photosynthesis will be high. Introduction Photosynthesis is the process of converting energy from sunlight

Aerobic cellular respiration and oxygenic photosynthesis are the main pathways of energy flowing in living things. Photosynthesis is known as a process that is used by plants, algae and bacteria get energy from sunlight into chemical energy. Aerobic cellular respiration makes ATP, finalizes e- acceptor is oxygen. Aerobic cellular respiration involves the products of photosynthesis, which are glucose and oxygen, while photosynthesis uses the products in aerobic cellular, which are carbon dioxide and

Introduction Photosynthesis is the process whereby chlorophyll containing cells in green plants convert incident light to chemical energy and synthesise organic compounds from inorganic compounds (Great Illustrated Dictionary, 1984). It could also be presented by this equation (6CO2 + 6H2O  C6H12O6 + 6O2), all in the presence of sunlight (Mader, 2010). The word photosynthesis means “putting together with light” (Ashley, 2000). In order for plants to photosynthesis, a source of light energy is needed

Photosynthesis and Respiration: Cellular respiration and photosynthesis are the two main processes carry out by most living organisms to attain energy. Whereas photosynthesis is performed by most plants that can make their own food, most animals achieve their energy necessities through cellular respiration. Photosynthesis: Light-dependent Reactions and Light-independent Reactions or dark reactions or Calvin Cycle are the stages of chemical reactions during the process of photosynthesis. Light Reactions:

Haya Al-Khater Mr. Gurney Biology HL December 1, 2014 The Effect of Light intensity on rate of photosynthesis Research question- How does light intensity affect the rate of photosynthesis in Spinach leaves (Spinacia oleracea)? Hypothesis- My hypothesis is that light intensity and photosynthesis rate have a positive correlation. Meaning that as light intensity increases, photosynthesis rate will increase. This is because as light intensity increase, the rate of light-dependent reactions increase

In photosynthesis, carbon dioxide and water are used to produce glucose and the by-product oxygen, and there is an intake of energy. In respiration, on the other hand, glucose and oxygen are broken down into carbon dioxide and water, and there is a release of energy. Basically, the products of one serve as the reactants of the other, and vice versa. As the name suggests, light-independent reactions do not need the presence of light to function. The process occurs in the stroma and it produces G3P

Photosynthesis is the process the energy from sun lights to produce ATP which is used to make sugar such as glucose, sucrose, cellulose, and starch. Photosynthesis involves two different processes, which are light dependent reaction and light independent reaction. Light dependent reaction requires light energy to split water molecules (photolysis) into hydrogen ions (H^+), oxygen (O_2) and electrons to make ATP and the light dependent reaction allows plants to grow and make a waste product (oxygen)

Crabtree Period 4 Accelerated Biology 11/20/15 Photosynthesis in Greenhouses Farmers use their knowledge about photosynthesis to increase crop growth every year. Greenhouse conditions are more easily controlled, rather than the air outside. Changing certain variables in the process of photosynthesis can change the outcome of the crops. One variable that farmers change is the temperature. Plants need an optimum temperature to have a sufficient photosynthesis rate, but different plants have different optimum

process of photosynthesis, in which carbon dioxide and water is taken in by autotrophs, along with sunlight, to make glucose and oxygen. Autotrophs include any photosynthesizing organisms, such as plants and algae, all of whom also undergo respiration. The products of photosynthesis are taken in by heterotrophs, organisms who cannot make their own energy and rely upon autotrophs for food. The by-products of their respiration - carbon dioxide and water - are then used for photosynthesis. Gas exchange

Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Most autotrophs use sunlight to make food, the process is called photosynthesis. Plants, algae, and some bacteria can use photosynthesis. The reactants of photosynthesis are carbon dioxide and water, captures energy into chemical bonds. The products are sugar and oxygen. Plants take carbon dioxide and water and turn it into sugar and other compounds. Sugar is produced and used by plants for its life process, like
