EPIDERMAL CELLS INRODUCTION A living plant cell will shrinks or swells depending on the solute concentration of the cell in relation to the solute concentration of the fluid surrounding the cell (1). It follows that water will move from a region of high water concentration to a region of low water concentration therefore‚ if a cell is placed in a hypertonic solution water will move from the cell into the solution until the cell shrinks(1). Further water loss causes can cause the cells protoplasm

TOPIC 3.7 + 8.1: CELL RESPIRATION 3.7.1 Define cell respiration. Cell respiration is the controlled release of energy from organic compounds in cells to form ATP (adenosine triphosphates). 3.7.2 State that‚ in cell respiration‚ glucose in the cytoplasm is broken down by glycolysis into pyruvate‚ with a small yield of ATP. Glycolysis in cytoplasm: Glucose 2 pyruvates + small amount of ATP (does not use oxygen) 3.7.3 Explain that‚ during anaerobic cell respiration‚ pyruvate can be

The Onion Cell Lab Background: Onion tissue provides excellent cells to study under the microscope. The main cell structures are easy to see when viewed with the microscope at medium power. For example‚ you will observe a large circular nucleus in each cell‚ which contains the genetic material for the cell. In each nucleus‚ are round bodies called nucleoli. The nucleolus is an organelle‚ which synthesizes small bodies called ribosomes. Ribosomes are so small you cannot see them with the light microscope

Everglades University Mr. Kirk Webster Sickle Cell Anemia Sickle cell anemia or also known as sickle cell disease is a hereditary genetic disease defined by the presence of odd shaped crescent-shaped red blood cells instead of the regular round disc like shape cells. Red blood cells transport oxygen from the lungs to various other organs and tissues with the help of a protein called hemoglobin. The main cause of sickle cell disease is when hemoglobin mutates into an abnormal type called

Human Embryonic Stem Cell Research Should Not Be Banned According to John A. Robertson‚ co-chair of the ethics committee of the American Society for Reproductive Medicine‚ “In November 1998‚ a team of researchers at the University of Wisconsin and a team at Jonhs Hopkins University published reports of the first successful isolation and culturing of human ES cells”(qtd. in Ruse and Pynes‚ 121). For over a decade‚ many researchers have thought that human embryonic stem cells could be the “Holy

difference between plant and animal comes down to cell structure. Animal cells do not have cell walls and have different structures than plant cells. Plant cells only are in rectangular shapes but animal cells are either circular‚ irregular or defined shapes depending on the type of cell. Plants have 3 basic organs; roots‚ stems‚ and leaves. Plants lack a brain and all the organs that animals have to carry out metabolic functions as animals take their carbon from organic substances and plants take their
