energy from the sun and use it to form starch molecules. The process by which this happens is called photosynthesis and results in the formation of oxygen and glucose. Plants take in carbon dioxide‚ water‚ and light then release oxygen back into the air. This process happens because of the movement of hydrogen to the hydrocarbons that are produced during photosynthesis. The discovery of photosynthesis is attributed to Dutch scientist Jan Ingenhousz who was the first to find that light is necessary to

6.1 Overview of Photosynthesis 6.1.1 Identify the cellular structures where photosynthesis occurs. A: It occurs in plants inside of the chloroplast 6.1.2 Locate the structures within a chloroplast and list their functions. A: A double membrane surrounds a fluid-filled area called the stroma. A third membrane system within the stroma forms flattened stacks called thylakoids‚ which in some places are stacked to from grana. The space within each thylakoid is believed to be connected to the space

How does light intensity affect the rate of photosynthesis? Poorly Pondweed Questions 1) How does light intensity affect the rate of photosynthesis? 2) How does temperature affect the rate of photosynthesis? sunlight carbon dioxide + water glucose + oxygen chlorophyll sunlight 6CO2 + 6H2O àààààà C6H12O6 + 602 chlorophyll Prediction I predict that the more intense the light‚ the higher the rate of photosynthesis. To photosynthesise‚ plants need light. It provides the energy for the process

Separation of Amino Acids by Cation Exchange Chromatography Introduction and Purpose: Amino acids are small biomolecules that have a carboxylic acid backbone in common‚ as well as an amino group attached to a saturated carbon. There are many amino acids‚ but there are 20 most commonly know amino acids. Amino acids are the fundamenta building blocks of other biomolecules like proteins and ezymes (Davidson‚ 2015). This experiment examined a mixture of 3 amino acids. The purpose of this experiment

Mobile liquid phase is always passed stationary phase during chromatography. Developed TLC plate is then observed under short wave ultraviolet light‚ where most TLC plates contain fluorescent mixed with silica gel that allow to glow green color. Compounds will absorb the UV light and appear as dark spot against the green color TLC plate. In a column chromatography‚ cotton and sand is placed in purpose of holding silica gel and prevent leakage of adsorbent particles

mobile phase can be liquid‚ gas‚ or supercritical fluid. How Does Chromatography Work? Chromatography is a surface effect. It works by first starting off with an unidentified liquid being injected into a column. As the chemicals in the liquid move down the column‚ they separate depending on their physical and chemical attributes‚ such as speed and weight. To easily picture the process‚ the example will pertain to a paper chromatography process in which the liquid is moving over the paper‚ separating

water in front of the test tube(containing the pondweed) because the water in the beaker will absorb the heat coming from the light bulb. The plant will not be affected by the heat and due to my previous research it will result in faster rate of photosynthesis and plant will survive longer. Each of my experiments will be 60 seconds long to get decent measurable results. The light source I will be using has a voltage of 35V and will have a beaker of water in front of it‚ and 15cm away front he end of

Photosynthesis is the process of transforming light energy into chemical energy that is used to build carbohydrates. Light reactions occur in the thylakoid membrane of the chloroplast‚ sunlight and water are the substrates for this reaction. The conversion of light energy can go through two pathways: noncyclic and cyclic. In noncyclic light transport‚ both Photosystems II and I are involved producing ATP and NADPH. Photosystem II absorbs 680 nm of light energy‚ with the oxidation of water; chlorophyll
