    Photosynthesis Lab Photosynthesis is the process by which plants covert sunlight, water, energy, and carbon dioxide into glucose. A byproduct of photosynthesis is the oxygen as a result of water molecules being split in the electron transport chain. This can be shown in the equation: 6H2O + 6Co2 + Light  C6H12O6 +6O2. Essentially, plants are converting solar energy into chemical energy. Examples of organisms that perform photosynthesis are plants, bacteria, algae, and proteus. Plants obtain energy

    ________________________________________ 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

    Plants get their energy from a process called photosynthesis, which occurs in organelles called chloroplasts. Chloroplasts contained multiple colored pigments that aid in the photosynthetic process. There are two types of colored pigments: yellow pigments or carotenoids, and green pigments or chlorophylls. Both categories of pigments also include other types of pigments and all are essential for carrying out photosynthesis and each have a role for helping plants receive energy (Pavia et al 208).

    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

    and dark would have on photosynthesis and cellular respiration. With the knowledge gained in class about how both the reactions took place. It was predicted that the absence of light would slow down photosynthesis causing less O2 to be released in the water. It was also predicted that the beaker with the fish in the water would yield a higher concentration of CO2 in the water. These predictions were made based on the fact that plants use the energy from light in photosynthesis to split H2O creating

    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

    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

    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

    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

    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

    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)
