Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves‚ and little to none occurs in stems‚ etc. The parts of a typical leaf

EXPERIMENT: 1 Object: To find the wavelength of Sodium light by Newton’s ring. Apparatus required: A Plano convex lens of large radius of curvature‚ optical arrangement for Newton’s rings‚ plane glass plate; sodium lamp and traveling microscope. Formula used: The wavelength of light is given by the formula λ =D n2+p –Dn2 / 4pR Where D n+p = diameter of (n+p)th ring Dn = diameter of n th ring‚ P = an integer number‚ R = radius of curvature of the curved face of the Plano- convex lens.

Transpiration and Leaf Resistance By: Bernina Berber Introduction Transpiration is a part of the water cycle process‚ and it is the loss of water vapor from parts of the plants. It is a process similar to evaporation. Evaporation and diffusion cause the plant tissue to have negative water potential. If you were to compare transpiration it would be like saying it is close to sweating (but in plants)‚ especially in leaves but also in stems‚ flowers and roots. Stomata are dots with openings on

BIOLOGY Coursework Photosynthesis Made By: Mike Alexander= Definition: Photosynthesis is a process by which plants make their own organic‚ complex food (glucose) from organic‚ simple‚ raw materials using sunlight energy (which is converted to chemical energy) and enzymes in the chloroplasts (mainly mesophyll cells called palisade cells). How It Works: Carbon Dioxide + Water  Glucose + Oxygen 6CO2

Misael Acosta Photosynthesis Lab Report Ms. Rocha AP Biology 4th Period II. Intro/Background 1. In order for oxygen to be present photosynthesis must occur. Photosynthesis takes in light and CO2‚ and through a series of steps produces oxygen. Photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. Examples include the production of O2 or the consumption of CO2. All the oxygen within the leaf disks will be removed before being placed

Introduction Photosynthesis is a redox reaction which requires carbon dioxide‚ water and light to produce water and a 6-carbon sugar. The process of photosynthesis consists of two parts‚ a light reaction and a light-independent reaction. The method of changing light energy into chemical energy for the formation of NADPH and ATP is done through the light reactions. Light independent reactions use carbon dioxide and the products of light reactions (ATP and NADPH) to form compounds such as glucose

Title: Rate of Photosynthesis Introduction: Photosynthesis occurs in plants where the light energy changes to chemical energy. This process occurs in the chloroplast of the plant cell in order to have gas exchange in the organism. Purpose: To measure the effect of light intensity on the rate of photosynthesis in the leaf cells. Hypothesis: The higher the concentration of the sodium bicarbonate solution‚ the faster the leaf of the plant will rise to the surface of the water in the beaker‚ the

Abstract Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water‚ PO4 buffer‚ and chloroplast will be prepared in a number of cuvettes. The cuvettes were tested individually at different wavelengths and intensities to find the optimal rate
