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

Bio Block B Photosynthesis Lab 12/6/12 Introduction: Photosynthesis is affected by light intensity‚ water‚ and temperature. Plants grow more abundantly because the weather is warm. Carbon Dioxide given off by animals is consumed by plants that replace the oxygen animals take it. Experimentation will help understanding how plants are vital because of the oxygen they release. If leaf disks in the experiment release oxygen‚ they will undergo photosynthesis and float. If there

The Effect of Distance from Light Source on the Rate of Photosynthesis Introduction: The effect of distance from the light source on the rate of photosynthesis was tested in this experiment. This was tested to find ways to accelerate the rate of photosynthesis. If plants are placed closer to a source of light‚ then their rate of photosynthesis will be higher because they are receiving more light. Experimental Design: The independent variable is the distance of the beaker from the light source

The respiration and photosynthesis cycle is the process by which plants and animals interact in a codependent and symbiotic manner to produce the nutrients‚ gases‚ and energy that they require to survive. Plants obtain energy from sunlight and use it to combine carbon dioxide and water into glucose and oxygen. This process is called photosynthesis. Animals eat plants containing glucose‚ and combine glucose and oxygen‚ releasing energy‚ water‚ and carbon dioxide. This process is called respiration

PAPER #1; PHOTOSYNTHESIS AND CELLULAR RESPIRATION Name: Melvin G. Abramson SCI 115 – Essentials of Biology Professor: Casey Bethel Date: May 1st‚ 2012 Photosynthesis is the progression of translating light energy to chemical energy and storing it in the acquaintance of sugar. This process occurs in plants and some algae. Photosynthesis takes place in the chloroplasts‚ distinctively using chlorophyll‚ the green pigment implicated in photosynthesis. Photosynthesis

is called photosynthesis. This process is used by plants and other organisms for synthesis of lipids and amino acids or can be metabolized during cellular respiration to produce ATP. This process takes place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions. Throughout our lab experiment‚ we focused on the affect access of light has on carbon dioxide during photosynthesis. Carbon

complexes. Chlorophyll molecules use their energy to strip water molecules‚ and biological molecules then adding hydrogen to them. In prokaryotes instead of chloroplast they use their own cell membranes to do the job. Wavelength also has a role in photosynthesis because they have just the right amount of energy to excite chlorophyll electrons boosting them to a higher energy level. When summing everything up the reactants are carbon dioxide‚ water‚ and the suns energy and the process is light dependent

Cellular Respiration and Photosynthesis Photosynthesis is the process by which plants‚ some bacteria‚ and some protistans use the energy from sunlight to produce sugar‚ which cellular respiration converts into ATP‚ the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy‚ is associated with the actions of the green pigment chlorophyll. Most of the time‚ the photosynthetic process uses water and releases the oxygen. Cellular respiration

of ATP. Although both processes are found in double membraned organelles‚ photosynthesis occurs in chloroplasts in plant cells and cellular respiration occurs in the mitochondria of animal cells. Photosynthesis uses water and carbon dioxide as reactants to produce glucose and oxygen where as cellular respiration uses glucose and molecular oxygen as reactants to produce water‚ carbon dioxide‚ and energy (ATP). Photosynthesis is a two part process which includes photophosphorylation (light reactions)

This means that the light intensity actually has an impact on the plant’s photosynthesis levels. The reason that there are more bubbles in the experiments with more light is because of the oxygen release rate. With more light intensity‚ the rate of photosynthesis happens faster. Since the process of photosynthesis release oxygen‚ the more oxygen will be released creating the bubbles underwater. To clarify‚ photosynthesis is the process of which a plant’s chloroplasts‚ with the aid of the sun (or
