plant in the Chenopodiaceae family. It is best known in its numerous cultivated varieties‚ the most well known of which is probably the red or purple root vegetable known as the beetroot or garden beet. However‚ other cultivated varieties include the leaf vegetables chardand spinach beet‚ as well as the root vegetables sugar beet‚ which is important in the production of table sugar‚ and mangelwurzel‚ which is a fodder crop. Three subspecies are typically recognised. All cultivated varieties fall into

THE POTENCY OF TALISAY terminalia catappa AS FABRIC DYE By: Charlene Angelica B. Buenvenida Chapter I INTRODUCTION Dyes have become part of daily living. What’s great about dyes is that they give variety to everything. Even the earliest humans used dyes to put color into their worlds‚ and they even used the most peculiar sources of the colors. Since then‚ dyes have dominated different kinds of industries. Before‚ dye manufacturers were only able to produce one color at a time. But

reaction. The light reactions converts light energy to chemical (Biology.clc.uc.edu‚ 2014). This chemical reaction must take place in the thylakoid membrane. Chlorophyll (the green pigment involved in photosynthesis) and several other pigments are organised in clusters in the above membrane (Bailey‚ 2014). Each of these pigments are differently coloured and can absorb a slightly different colour of light and pass its energy to the central chlorophyll molecule to do photosynthesis. Light contains all the

Medicinal Plants Introduction Introduction “In All things there is a poison‚ and there is nothing without a poison. It depends on only upon the dose whether a poison is a poison or not”---------Paracelsus (1493?-1541‚ Switzerland) Chinese saying “Shi Yao San Fei Du” means “Any drugs have toxic effects”. Introduction: Why Study Medicinal Plants Medicinal plants and religions • Medicinal plants have played an essential role in the development of human culture‚ for example religions

consisted of three smaller experiments as a result of the different properties chlorophylls possess and the need to test them individually to receive the most accurate results. Preparation for the lab began with selecting a medium to large spinach leaf and deveining it. Once the spinach was prepared‚ it was ground in 5 mL of 100% acetone‚ creating a green acetone extract. The extract was filtered through a funnel with a kimwipe and into a test tube. The volume of the filtered extract was estimated

that have divided beneath the ground. Illustration from Curtis’s Botanical Magazine by William Curtis (1746–1799) The leaf blade is divided into two regions: a flat‚ heart-shaped photosynthesis-capable petiole‚ and a pair of terminal lobes hinged at the midrib‚ forming the trap which is the true leaf. The upper surface of these lobes contains red anthocyanin pigments and its edges secrete mucilage. The lobes exhibit rapid plant movements‚ snapping shut when stimulated by prey. The trapping

Abstract: Two parts of this lab were performed involving photosynthesis and cellular respiration. The first part of the lab consisted of cutting out spinach leaf disks with a straw and then putting them into syringes containing an infiltration solution and sodium bicarbonate. Then the syringes were place under the presence of light and watched as certain disks floated. This part of the lab consisted of watching photosynthesis take place. Then for the second part of the lab we tested cellular respiration

and captured by the plant’s leaves to perform Photosynthesis. Photosynthesis occurs in organelles within plant leaves called chloroplasts. Chloroplasts contain chlorophyll‚ a light absorbing pigment that in different variations absorbs different wavelengths of light‚ as well as other light absorbing pigments like carotenoids and hydrocarbons (Campbell‚ 2008). Chlorophyll a and b along with carotenoids each have a different absorption spectrum that allows them to process a different wavelength of
