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

SICKLE CELL ANEMIA Dillon Lukacs Normal Circulatory system In a normal circulatory system blood flows easily through the veins and arteries. Oxygen is delivered throughout the body to all the vital organs. Sickle Cell Disease An anemia is a condition where there are less red blood cells than normal. Sickle cell anemia is a disorder where the body creates sickle or crescent shaped red blood cells. In a normal blood cell they look like donuts with a hole in the middle. This shape helps them

three main parts of a cell. plasma membrane-forms a cell’s flexible outer surface‚ separating the cell’s internal environment (inside the cell) from its external environment (outside the cell) cytoplasm- consists of all the cellular contents between the plasma membrane and the nucleus. nucleus- is the largest organelle of a cell. The nucleus acts as the control center for a cell because it contains the genes‚ which control cellular structure and most cellular activities The cell is the basic‚ living

Julia Babin Ms. Bukola 11/6/2012 Bio Lab W 8 Cell Structure and Function Prokaryotic cells do not contain a nucleus. Eukaryotic cells do contain a nucleus. Organisms are eukaryotic except Bacteria and Achaea. Organelles are small membranous bodies‚ each with a specific structure and function. Prokaryotes do have cytoplasm‚ which is the material bounded by a plasma membrane and cell wall. This contains ribosomes‚ small granules that coordinate the synthesis of proteins

favored communication hub for the majority of American teens. 1 Cell-phone texting has become the preferred channel of basic communication between teens and their friends and cell calling is a close second. Some 75% of 12-17 year-olds now own cell phones‚ up from 45% in 2004. Those phones have become indispensable tools in teen communication patterns. Fully 72% of all teens – or 88% of teen cell phone users — are text-messagers.2 That is a sharp rise from the 51% of teens who were texters in 2006

advantages of cellphone. It helps people to overcome the obstacles of space to be able to communicate easily and effectively and enjoy many kinds of entertainment. The first advantage of cellphones is that (is to keep ) people can keep in contact with each other wherever and whenever. Even when you are not at home or are out of the office‚ others still can contact you. This advantage is very useful in emergency situations‚ for example‚ when you get lost or have an accident‚ you can call others for help

Circulatory System of Frogs vs. Circulatory System of Humans The circulatory system of a human compared to that of a frog is different due to the number of chambers each contains. A frog’s heart has three chambers (two atria‚ and a single ventricle)‚ whereas a human’s has four (two atria‚ and two ventricles). The atrium of a frog receives deoxygenated blood from the blood vessels that drain the various organs of the body. The left atrium receives oxygenated blood from the lungs and skin. Both

Eukaryotic & Prokaryotic Cells Introduction: The Cell: The cell is a functional unit of all living organisms. Cells have evolved into two fundamentally different types‚ eukaryotic and prokaryotic‚ which can be distinguished on the basis of their structure and the complexity of their organization. The simplest organisms which consist of one cell are called prokaryotes. More complex organisms are called eukaryotes and they consist of many cells. Objectives: * Define the terms: Eukaryotes

Ever since I watched the show Grey’s Anatomy‚ my interest in the human body system began. I was fascinated with the way the body works and all the different things that cause our bodies to react in a certain way. What amazes me is the things we can do in order to prevent ourselves from putting our bodies through things that can cost us our lives. What I want to get out of this class is to learn way more about the human body. I would also like to get into depth about some of the things I know already
