Describe the importance of the specific environmental conditions under which your plants are being grown. Why are the plants grown on a nutrient agar? What macro and micronutrient elements are necessary for successful plant growth? What biological processes and fern structures (if any) are used by the gametophytes to

Bacterial Smears Are Fixed before Staining to? Answer It is important to heat fix the bacterial smear before staining so as to‚ kill the bacteria‚ firmly adhere the smear on to the microscopic slide to prevent washing off during staining‚ and to allow the sample to readily take up the stain. Reference: www2.hendrix.edu What is the purpose of heat- fixing the smear? It helps the cells adhere to the slide so that they can be stained. The purpose of heat fixing is to kill the organisms without

Chapter One INTRODUCTION Herbal medicines tend to look primitive and unscientific when compared to synthetic (conventional) drugs‚ which are thought to be more reliable than those made from plants. Herbal medicine is still the mainstay of about 75-80% of the world population‚ mainly in the developing countries for primary health care (Kamboj‚ 2000). This is primarily because of the general belief that herbal drugs are without any side effects‚ besides being cheap and locally available. The

The unknown bacteria samples for the endospore stain were taken off of a nutrient agar plate and stained using the Bartholomew and Mittwer’s method. Gram stain samples were taken off of tryptic soy agar and stained using the gram stain procedure that is listed in the Willgoh and Bleakly manual (2).

Endospore and Capsule Cell Staining Allison Lui Partner: Mary Chagin BIOL-235 W07 Dr. Runco 2/10/15 Introduction The purpose of this lab is to learn what endospore and capsules are‚ and how to identify them under a microscope using capsule and endospore staining methods. Capsules are found only in select bacteria‚ and serve a protective purpose. Made out of sugars and proteins‚ they are antiphagocytic‚ which prevents other cells to engulf the bacteria through phagocytosis. It
