DATE: 2011/09/27 LAB NO.: 4 SYLLABUS TOPIC: Cellular structure AIM: To draw a tissue map of a dicotyledonous root. APPARATUS AND MATERIALS: Microscope‚ slides of the dicotyledonous root‚ and drawing materials such as pencils‚ ruler‚ and an eraser. METHOD/PROCEDURE: -The microscope was set on the tabletop (a flat‚ sturdy surface) where there was plenty of room to work with and was plugged into a power source. -The slide of the specimen (dicotyledonous root) was placed onto the stage of the

Nutritional requirements The composition of medium for the tissue culture is the most important key factor in the successful culture of plant cells. The medium should be accurately defined of inorganic and organic chemical additives so as to provide i) the nutrients for the survival of the plant cells‚ tissues and organs under culture and ii) the optimal physical condition of pH‚ osmotic pressure‚ etc. In the culture of plant cells formulating optimum type of medium favorable for in vitro

"Abbreviated progressive muscle relaxation (APMR) is a shortened version of Jacobson’s (1939) original technique‚ designed to induce feelings of deep relaxation by systematically tensing and relaxing 16 muscle groups and by learning to focus on and discriminate between the resulting sensations of tension and relaxation." It has been proven that APMR has reduced levels of anxiety and stress‚ while increasing positivity. APMR has also has also relieved headaches caused by tension in some people (Chellew

Fetal Tissue Transplantation”‚ by Scott B. Rae. This article covers strong points such as science‚ laws‚ ethics‚ restrictions‚ and alternatives. With all the information presented in this article I find it extremely unethical to use fetuses from voluntary abortions to assist in medical care. In 1988 there was an experiment done on a 52-year-old man with Parkinson’s disease. They implanted fetal brain cells in his brain. He reported an improvement in his ability to walk and speak.

arm motion all working together to strike the ball at the right time in the proper manner. The list of muscles involved in these movements is very long. Among them are the quadriceps and hamstrings in the legs‚ deltoids in the shoulders‚ and triceps‚ biceps‚ and the muscles of the hand and forearm. A person studying the biomechanics of volleyball would be concerned with these and other related muscle

Objective: To study osmosis in living plant tissue. Biological principles: Water potential is the tendency for water molecules to enter or leave a system by osmosis through a differentially permeable membrane‚ while osmosis is the process in which water molecules move passively from a region of higher water potential to a region of lower water potential through a differentially permeable membrane. Therefore‚ potato cells‚ with their differentially permeable membrane‚ are selected as the medium

always propagated in a micro way‚ tissue culture is the most popular method for micro-propagation in Alstroemeria. Tissue culture involves the use of small pieces of plant tissue (explants) which are cultured in a nutrient medium under sterile conditions. Using the appropriate growing conditions for each explant type‚ plants can be induced to rapidly produce new shoots‚ and‚ with the addition of suitable hormones new roots. Alstroemeria explants used in tissue culture consist of a rhizome

CHAPTER 3: THE MUSCULAR SYSTEM Three Types of Muscle * Muscle tissue is a collection of cells that shorten during contraction which create tension that results in movement * Tendons are touch bands of connective tissue that join muscle with bones Skeletal muscles * Muscles that are attached to bone (by tendons and other tissue) * Comprise 30 to 40% of human body weight * Humans have conscious control (conscious muscle) over these muscles (the brain can tell them what to do)
