Photosynthesis

Photosynthesis and Leaf Structure Experiment Introduction The primary function of leaves is to conduct photosynthesis, a biochemical process in which plants, as well as a variety of bacteria and protists produce food from sunlight (EEB, 2016). Photosynthesis requires the acquisition light, water, and carbon dioxide and the removal of oxygen. Sodium bicarbonate is added as the bicarbonate ion acts as a carbon source for photosynthesis. Light independent reactions are catalyzed through the power…

Photosynthesis and sexual reproduction are the two main turning points in the history of life, because the ability to process energy from sunlight, random variation and non-random selection allowed for evolutionary growth and the survival of life. Photosynthesis, an important process of energy transformation is crucial in the development of metabolic microorganisms, as well as the evolutionary changes from primitive to more complex life. Sexual reproduction displays a significant evolutionary…

each other. In photosynthesis, carbon dioxide and water work together with the protein complexes present in the chloroplast and with the aid of the energy coming from the sun to yield glucose and oxygen. Meanwhile, in cellular respiration, glucose is broken down with the aid of oxygen and enzymes present in the mitochondria into carbon dioxide and water, which are the starters of photosynthesis, and produces energy in the form of ATP. The light independent (LI) reactions of photosynthesis take…

oxygen is produced by photosynthesis and consumed at the same time by respiration. An oxygen electrode recorded the concentration of oxygen in the chamber, throughout each stage of the experiment. This was used to calculate the rate of photosynthesis and respiration. Introduction Photosynthesis is the most important process on earth. It provides the energy for photoautotrophs to make their food for heterotrophs and is an anabolic process (Reece et al, 2015). Photosynthesis occurs in the…

Abstract: For this lab my group and I wanted to measure the rate of photosynthesis. We did this lab twice, both with slightly different environments so that we could see what changing the factors did to the rate. We found the rate of photosynthesis by taking hole punched pieces of a leaf and placing them inside of a syringe with sodium bicarbonate buffer. We then pulled the plunger part of the syringe back which lets the bicarbonate solution infiltrate the air spaces in the piece of leaf. After…

Introduction: Photosynthesis is the process used by plants, algae and some bacteria, to use the energy from the sunlight to transform carbon dioxide and water into glucose and oxygen. The equation for photosynthesis is: carbon dioxide + water light energy glucose + oxygen. Chloroplasts are an organelle found in the leaves of green plants and are essential in photosynthesis as they are responsible for producing the glucose and storing the energy. Photosynthesis is vital for all life on…

Color and Photosynthesis Rate Introduction: How do the wavelength of visible light affect photosynthesis? Photosynthesis, a process used by plants and other organisms to convert light energy into chemical energy that can be released later to fuel the organisms’ activities, depends upon the absorption of light by pigments found in the plant leaves. Pigments, such as chlorophyll and carotenoids, absorb and reflect light based on the wavelength of light. To be more explicit, photosynthesis is the…

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 site of photosynthesis is the chloroplast, which are disc-shaped organelles found in the mesophyll of the leaf in the palisade layer. They have outer and inner membranes with an inner membrane space between them. The stroma in the middle of the chloroplast contain membrane discs…

Photosynthesis Photosynthesis is the process by which plants, algae, and various bacteria’s are used to capture energy from sunlight into chemical energy (Vidyasagar). This is very important process because it will then use the glucose, which will be used by cellular respiration to make ATP. The ATP will then be used to fuel all living organisms. Photosynthesis has two processes a light dependent reaction and the light independent reaction. A Light Dependent Reaction absorbs and converts light…

Photosynthesis is a biochemical process from light using energy from sunlight and carbon dioxide from the atmosphere as reactants to produce oxygen and organic compounds like carbohydrates (Campbell et al. 2015). Photosynthesis takes place in photoautotrophs including all plants, algae, some kinds of bacteria, and protists. The simplified equation is: CO2 + H2O → carbohydrates + O2. (Sadava et al. 2014). It is broken down into two parts: light reaction and light-independent reaction (Campbell…
