Comparing Plant and Animal Cells Hypothesis: I predict I will see the following organelles when observing a plant and animal cell under a microscope: the cell membrane‚ cell wall‚ nucleus‚ and the endoplasmic reticulum. Frog Blood: Analysis: 1. The shape of the frog blood cell was in a circle‚ or oval. The edges were a little irregular‚ but it could still be identified as‚ basically‚ a circular shape. 2. The cells were produced by an animal‚ a frog. 3. The cell wall was not present

Chapter 2 IB Biology 2.1 Cell Theory 2.1.1 Outline the cell theory (2). • All organisms are composed of one or more cells • Cells are the smallest units of life • All cells come from preexisting cells • TOK: cell theory replaces the former ideas of spontaneous generation or abiogenesis in which inanimate matter assembles itself into living forms • Exception: muscle cells- more than 1 nucleus‚ very long; (fungal cells) hyphae roots- not a single unit; protoctista- not specialized to single

Professor Derek J. Thiess Rhetoric 105 29th Nov‚ 2010 Embryonic Stem Cell Research Over the last decade the use of stem cells has been a controversial and heated topic. Debates have exploded over every aspect of stem cell research in nearly every region of the world. Every aspect of stem cell research has come under debate in nearly every region of the world. It has been speculated by scientists that stem cell research may have the power to potentially cure incredibly harmful diseases or

Cell Structure and FunctionAbstractThis report is about cell structure and function. The cell is the basic unit of life. All living things are madeof cells. By doing this lab‚ I hoped to learn how a cell looked and how it functioned. I also wanted toknow the differences between prokaryotic cells and eukaryotic cells.IntroductionThe concept of this lab is producing a replica of an animal cell‚ and a plant cell. Producing the models of the cells helps to provide a better understanding of each cell

Cell Phones Are Here To Stay Today cell phones have become like an accessory that accents our wardrobes. Cell phones are used for far more than just phone calls anymore. Some may even argue that they have become a distraction‚ a nuisance‚ or annoying even. At the end of the day‚ most of the people that would make this claim prove to be hypocrites and own a personal cell phone their own. Almost anything needed is virtually at fingertips. This one device has brought communication to your fingertips

CHAPTER 1 Cell Structure and Organisation Cells * All living organisms are made up of cells * The simplest living organisms have one cell only * His name is unicellular-e.g. bacteria. * Most other living organisms have many cells- his name is multicellular- e.g. Man‚ plants‚ animals. * Cells can be seen only under microscope Cell structure All cells have the following structure in common: a) Cell membrane- a very thin layer of protein and fat‚ surrounding the cell. It is

Abstract Sickle-cell disease is a genetic disorder that results from the abnormal structure of red blood cells. The peculiar shape of the red blood cell prevents the normal absorption of oxygen. This disease results from the abnormal production of hemoglobin S (HbS). Therefore‚ a mutation in this gene causes a lower supply of oxygen to the cells‚ which results in occlusion of the blood vessels. Individuals diagnosed with sickle-cell anemia have abnormal function of the gene that encodes for subunit

Stem Cell Research: Should we continue to allow scientists to create new embryonic stem cell lines? Good morning everyone. The topic of Stem Cell Research has been argued over by politicians‚ scientists and people all over the world for over a decade. Scientists should not be allowed to continue to create new embryonic stem cell lines. One of the ways to obtain stem cells for scientific research is to destroy a blastocyst (laboratory-fertilized human egg). Destroying the blastocyst is the equivalent

Cell Phone Technology The cell phone technology that is ever changing by the day was scientifically invented and born back in the early 1980’s. Science was the main key to the birth of the cell phone which was put together by the Motorola Company who today is still making cell phones. Before the cell phone came out the car phone was the first mobile phone which were very large and had to be hooked up to a briefcase which supplied the power for the mobile phone. Science was the utilized to create

answer. b) Stem cells. A relative of a friend of yours had a spinal cord injury after a bad car accident. The medical team has decided that this patient is a good candidate for a clinical trial using stem cell therapy. Your friend has not had a biology course since high school‚ so you are going to write for him or her a two-page discussion of stem cell information. In your discussion‚ include a description of the biology of stem cells‚ and explain how these cells are unique in their
