Plant Tissues A mature vascular plant (any plant other than mosses and liverworts)‚ contains several types of differentiated cells. These are grouped together in tissues. Some tissues contain only one type of cell. Some consist of several. Meristematic The main function of meristematic tissue is mitosis. The cells are small‚ thin-walled‚ with no central vacuole and no specialized features. Meristematic tissue is located in • the apical meristems at the growing points of roots and stems. • the

fundamentals of science. Title An investigation of an onion cell using a light microscope. Aim: The aim of this investigation is to identify the cells within an onion skin using a light microscope. An onion cell is a plant cell which through the light microscope‚ it should outline the cell wall‚ cell membrane and the nucleus. Introduction: Plant cells have a cell wall and cell membrane which animal cells do not have. The cell wall provides support and is relatively rigid‚ which consists of

Cell division consists of two processes: mitosis and cytokinesis. Mitosis— division of the nucleus and its chromosomes— is divided into five phases:prophase‚ prometaphase‚ metaphase‚ anaphase‚ and telophase. Mitosis is followed by cytokinesis‚ when the cytoplasm splits to form two separate daughter cells. The cytoplasm of a cell in late interphase contains two centrosomes‚ each of which may contain a pair of centrioles. In the nucleus‚ the chromosomeshave been replicated during S phase‚ but are

The CELL THEORY‚ or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940). Ultrastructural research and modern molecular biology have

DETERMINATION OF THE WATER POTENTIAL OF POTATO TUBER CELLS. Method. Five sucrose solutions with varying molarity and one control containing distilled water were prepared and poured into test tubes. The potato discs were dried‚ weighed and added to the test tubes. The discs were then weighed again after a period of 24 hours. The percentage change in mass was then calculated. Apparatus.  Specimen tubes with stoppers x6  1cm3 diameter cork borer  razor

Blood Cells Leukocytes (WBC’s) Leukocytes also known as white blood cells (WBCs) are cells which play a defensive roll in the body against injury and infection. They migrate towards tissues where they are needed and become functional performing various activities. WBCs can be divided into 2 groups: Polymorphonuclear granulocytes and mononuclear agranulocytes. Both types are spherical while suspended in blood plasma but when they invade tissues after leaving the blood vessels they become amoeboid
