Osmosis Lab: Potatoes and Elodea Background Information: Cells have a need to regulate their internal environment. They need to be able to this because cells often find themselves in environments where the concentration of dissolved solids outside the cell is different from the number of dissolved solids inside the cell. Since the solids can not move across the membrane‚ the cell responds by moving water either into or out of the cell in an attempt to balance the number dissolved particles.

differences between cancer cells and normal cell. Some of the differences are well known ‚where as others have only been recently discovered and are less well understood.You may be interested in how cancer cells are different as you are coping with your own cancer or of a loved one. For many researchers understanding how does cancer cells function differently from normal cells foundation for developing treatments designed to rid the body of cancer cells without damaging normal cells.

STEM CELL RESEARCH AND THERAPYAND ITS IMPACTS ON SOCIETY Abstract There are several types of stem cells being used in stem cell research and therapy today. They are embryonic‚ adult and induced pluripotent stem cells. Each will be discussed further. This topic has stirred much moral‚ ethical and political debate as whether cells from fetuses should be used in this research. This impacts governmental policies on laws and funding. Another issue that must be analyzed is the

EXPLORING THE EGG CELL By: Christina Vu SNC2D3 Mr.Ram FUNCTION OF THE EGG CELL: The egg cell is the female gamete used for sexual reproduction. The egg cell is responsible for providing half of the genetic material required for reproduction. When the egg cell joins with the sperm cell.... The egg cell is large and bulky structure which allows the sperm cell to get in easily. WHAT ORGANELLES DOES AN EGG CELL HAVE AND THEIR FUNCTION? Mitochondria: Produces energy for the cell by a process called

How the Potato Changed the World In today’s world the potato is the fifth most vital crop universal‚ it follows wheat‚ corn‚ rice and sugar cane. However in the 18th century the potato was an amazing novelty‚ part of a global environmental fit started by Christopher Columbus. Roughly 250 million years ago‚ the world consisted of a single giant landmass now known as Pangaea. Physical forces broke Pangaea separately‚ creating the continents and hemispheres well-known today. Over the eons

Chemical Composition of Cells Testing for Proteins: The independent variable is the biuret reagent. The dependent variable is the solutions being used as follows; distilled water‚ albumin solution‚ and starch solution. If the protein is present‚ then the biuret will change to a violet color. Authors: Eliza Koundry and Jody Cote Eliza was in charge of adding equal amounts of biuret reagent to the distilled water‚ albumin solution‚ and the starch solution. Jody was

body‚ there are billions of cells that are essential to living – these are called nerve cells. Nerve cells‚ also known as neurons‚ “are the basic information processing structures” (Stufflebeam). There are about 100 billion of these neurons in our nervous system and are the most essential cell in it. Located in brain as well as the spinal‚ there are different types of nerve cells; including: sensory neurons‚ motor neurons‚ and interneuron (Boeree). The neuron is a cell that is structured similarly

Eukaryotic cells contain its DNA within its nucleus‚ while prokaryotic cells keep it within the nucleoid. Prokaryotic cells are also more minute than the eukaryotic cells. Also although they both contain ribosomes‚ they are composed differently. 3. The central vacuole (takes in water and chemicals)‚ cell wall (allows the plant to be strong enough
