Pre-Lab Questions 1. Identify the major similarities and differences between prokaryotic and eukaryotic cells. Similarities †¢ Eukaryotic and prokaryotic cells are both cells. †¢ Both types of cell have the cell membrane and the ribosome. Differences Prokaryotic cells Eukaryotic cells †¢ They lack a specific nucleus but have nucleoids. †¢ They lack the other cell organelles such as the endoplasmic reticulum, the mitochondrion, and the Golgi apparatus. †¢ They also have a circular DNA. †¢ Non-permeable cell membranes †¢ Found mainly in bacteria cells †¢ They have a specific nucleus †¢ Have the other cell organelles such as endoplasmic reticulum, the mitochondrion, and the Golgi apparatus. †¢ Cells have a linear DNA †¢ Selectively permeable cellShow MoreRelatedProkaryotic and Eukaryotic Cells853 Words   |  4 PagesEukaryotic Cells Cells are the basic building block of life. Cells can be either Eukaryotic or Prokaryotic cells. Organism can only contain either one but not both of them. Prokaryotic cells are usually much smaller than Eukaryotic and are less complex. Bacteria are made up of one or more prokaryotic cells. Bacteria are made up of one or more prokaryotic cells. While Eukaryotic cell are found inside plant and animal life. Eukaryotic are more advanced and larger. Prokaryotic cell were the firstRead MoreBiology Lesson Plan Eukaryotes and Prokaryotes663 Words   |  3 PagesA Semi-Detailed Lesson Plan in BIOLOGY Date: January 22, 2013 Time: 7:30-8:30 Section: BSEd-2B I.

All cells share certain structural and functional features and they are of almost universal occurrence in living organisms. Biologists have devoted a great deal of attention to its structure and the processes that go on inside it. They have recognised a major distinction betweenRead MoreScientific Method and Media Piece Article Essay715 Words   |  3 Pagesexperiments. The book â€Å"Campbell Essential Biology with Physiology† discusses how athletes today are using certain types of steroids to enhance their performance. However, do the steroids alone give them super abilities? Or is it a combination of both god given abilities and the steroids? This in my opinion is one of the most interesting scientific topics of today. After reading â€Å"Campbell Essential Biology with Physiology† it helped me understand how science/biology could explain this theory or hypothesesRead MoreThe Branch Of Biology : An Example Of Multinational Influence1304 Words   |  6 Pageslanguage. The diversity of influences endow spontaneity into art, refining its nature. Art such as the science of biology is an example of multinational influence. Biology helps humans understand themselves and the life surrounding them. As a result, it is a duty for humans worldwide to collaborate as a team, study the topic, and build upon the knowledge of biology. The branch of biology is a complex field, so it requires the assistance of nations globally to make it understandable. The study of lifeRead MoreEssay on The General Features of Human Cells1736 Words   |  7 PagesThe adaptation of cells to their functions,their size, and shape 1.THE GENERAL FEATURES OF HUMAN CELLS The cell is the structural functional unit of all known living organisms it is the smallest unit of an organism that is classified as a living and is often called the building block of life .Like ourselves, the individual cell that forms our bodies can grow reproduce, process, information, respond to stimuli and carry out an amazing array of chemical reactions ,as the twenty first centuryRead MoreEukaryotic Vs. Eukaryotic Cells1645 Words   |  7 PagesEukaryotes and prokaryotes There are only two types of cell in the world, these are eukaryotic and prokaryotic cells. They are both similar and different in many ways, for example prokaryotes are only a few micrometres in size whereas eukaryotes are between 5-100 micrometres and nearly 10,000 times the volume of that of a prokaryote. A chemical similarity between the two is that they both either contain or use proteins, carbohydrates, lipids and nucleic acids to store or create energy. Both eukaryotesRead MoreWhy We Study the Cell and Its Components.738 Words   |  3 PagesWhy We Study the Cell and Its Components The cell is the most basic form of life essentially. Anything that is living fundamentally is composed of cells. We study the cell because it is the simplest unit of all living organisms and to begin understanding life, we must realize the cell’s structure, whether it is about the different types of cells or how the cell functions. Biology is the study of life and for the human species; the cell is the most basic principle of life, which is why it is soRead MoreWhat Is Life?

A cell is â€Å"the structural, functional and biological unit of all organisms† (biology-online.org). The millions of cells that compose the body give life. These cells work together in synergy to perform the bodily functions God has given man to maintain homeostasis. The cells that work in harmony consist of an array of cells such as, epidermal, nerve, or muscle. As these various cells work together they form a biological machine to give life. Before the discovery the cell, many had
