1. tested and measured? The purpose of this experiment was to determine whether the dark or light coleus leaf had the presence of starch. We used a dark and light leaf to test the presence of starch and how much was produced. 2. Summarize the results and how the results were obtained. Be sure to note the reason for each treatment of the leaves. As appropriate‚ compare experimental samples to controls. Both leaves were boiled in water then placed in hot ethyl alcohol. After adding the iodine

The ANOVA Table Printer-friendly version For the sake of concreteness here‚ let’s recall one of the analysis of variance tables from the previous page: In working to digest what is all contained in an ANOVA table‚ let’s start with the column headings: (1) Source means "the source of the variation in the data." As we’ll soon see‚ the possible choices for a one-factor study‚ such as the learning study‚ are Factor‚ Error‚ andTotal. The factor is the characteristic that defines the populations

If the cutting has no meristem‚ mitosis will not occur and you will end up with a dead piece of plant material. In order to successfully grow a new plant through a cutting‚ your plant must have adventitious root growth which in order to deliver water and nutrients to the plant. Adventitious roots are created through cell potency where cells differentiate. The

Determining Photosynthetic Activity in Plants Using Different Wavelengths of Light and Pigmentation Abstract The roles played by light and pigmentation in photosynthesis were examined in the geranium and Coleus plant. In addition‚ the separation of certain pigments based on their molecular structure was also examined‚ with the use of paper chromatography. When different leaves of the geranium plant which were exposed to different wavelengths of light‚ photosynthesis proved to be most actively

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

are used to color‚ add protection and give texture to different kinds of objects around us. Paints have different components. Additives are pigments that give distinct effects on paints and special effects on the wall‚ woods and other materials. Coleus aromaticusbenth (oregano) is an herbal plant that can grow in any kind of soil. Some researchers from the University of Tennessee said that this plant can heal coughs of people and relieve the voice of others and it was effective in destroying dangerous

ABSTRACT The antifungal activity and minimum inhibitory concentration (MIC) of various plant extracts in different solvents such as hydro-alcohol (50 % v/v) and hexane of plants traditionally used as medicines as Valeriana jatamansi (Sugandhbala)‚ Coleus barbatus (Pathar choor)‚ Berberis aristata (Kingore)‚ Asparagus racemosus (Satrawal)‚ Andrographis paniculata (Kalmegha)‚ Achyranthes aspera (Latjiri)‚ Tinospora cordifolia (Giloei)‚ Plantago depressa (Isabgol) were evaluated against Aspergillus niger

Background of the Study This investigatory project is to be conducted to study the feasibility of Kalamansi (Citrus Microcarpa Bunge)‚ Oregano leaves (Coleus aromaticus Benth.) and Kakawate leaves (Gliricidia sepium (Jacq.) Steud.) as mosquito repellant lotion. As of today it is not only dengue virus‚ there is a new disease called chikungunya virus that is anarthropod-borne virus‚ of the genus Alphavirus‚ that is transmitted to humans by virus-carrying Aedes mosquitoes. There have been recent breakouts
