Column and Thin Layer Chromatography: The Separation of Spinach Pigment Abstract Spinach extract was separated into fractions containing compounds of similar polarity by column chromatography. Based on solid-liquid phase partitioning‚ this separation technique exploited the different polarity of the compounds in the spinach extract. Three fractions with different colors were obtained. The extract and its fractions were analyzed using thin layer chromatography (TLC). The TLC results showed that

The light reactions of photosynthesis contain two photosystems‚ two electron transport chains‚ and ATP synthase. These parts are embedded in the thylakoid membranes of a chloroplast. The photosystems contain a collection of chlorophyll molecules. Chlorophyll‚ which is the green pigment of leaves‚ absorbs light energy that excites electrons to a higher energy level. Energized electrons from photosystem I are passed down an electron transport chain and added to NADP+ to form NADPH. Electrons from photosystem

with other businesses rather than the end user. There are many different types of industry‚ but most of them can be placed into two categories Light and Heavy industry. These two industries are very similar in some respects and very different in other ways‚ however they both have a common purpose of producing and manufacturing goods. Opposite to light are heavy industries‚ which refer to large-scale industries. The industries that are categorised as heavy include manufactures of mass transport

Phenotype of Drosophila melanogaster Eye Pigment Mariam Rahmanyar 100486882 T.A: Zahra Mortaji BIOL 2020 Results: Our TLC plate showed all colours expressed by the pteridine pigments for the wild-type Drosophila as expected (Figure 1). The sample A mutant which was a bright-red eye mutant also expressed the same pigments as our wild-type. Compared to the wild type‚ sample A pigment spots were lower intensity in colour under the UV light (Figure 2). Sample B was a brown-eye phenotype

Light Transmission Through Liquids With Different Viscosities Introduction Aim This experiment investigates the effects of different liquid viscosities on light transmission. The results of this experiment could greatly benefit marine biologists or other marine scientists. This would help them figure out how their flashlights would work in different water conditions in the ocean. Background Research Spectrophotometers are devices that measure the amount of light absorbed by a certain liquid

Inheritance System of anthocyanin pigments in Brassica rapa. Introduction The observations of Brassica rapa in class revealed a variation in color. Brassica rapa‚ also called fast plants‚ was studied because as their name suggests‚ they are able to complete a lifecycle in a short period of time. (www.fastplants.org) The color variations we observed among the plants were that some had green stalks while others were purple. The pigment which gives plants their color is called anthocyanin.

Light Intensity Characteristics of Photocells The photoelectric effect is defined as the emission of electrons from a material by visible light. The cadmium sulfide photocell is used to act as a conductor once exposed to light‚ allowing light to travel through. However it also acts as an electric resister (an opposition to a current flowing in a circuit) once not exposed to light. The photocell serves today ’s cause in a sufficient manner. It is used for a variety of reasons but it is mainly

What is Light Pollution? Light Pollution Light pollution is artificial or outdoor light that creates glare and intrudes with the nighttime setting and the natural night environment. The artificial light that is produced by urban centres/ areas‚ diminish the view of stars and planets. These artificial lights can be seen all the way out in space! Satellite images show light pollution as well lit and glowing regions on a map at nighttime (see image below). These well-lit regions are mostly cities
