Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions

The Cell Cycle Mitosis: the process by which cells reproduce themselves‚ resulting in daughter cells that contain the same amount of genetic material as the parent cell. Interphase Prophase Metaphase Anaphase Telophase Cytokinesis Cell Division Occurs in a series of stages of phases Interphase occurs before mitosis begins Chromosomes are copied (# doubles) Chromosomes appear as threadlike coils (chromatin) at the start‚ but each chromosome and its copy(sister chromosome) change to sister

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: What is cellular respiration and what are its three stages? Cellular respiration is the complete cycle of a glucose molecule that happens to be using oxygen. The three stages of cellular respiration are: Glycosis‚ the Krebs cycle‚ and the electron transport chain. What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis is the

support‚ move‚ and protect the body; they also give us our features. But without bone cells we would have no bones. Bone cells are the living units that make up your bones and keep them functioning. Bone cells have two major roles‚ which are the production of new bones and resorption or destruction of old bone. They also carry out other small roles. There are four main types of bone cells: Osteogenic‚ which are bone cells that respond to traumas‚ osteoblasts‚ which form bone matrix around themselves by

CELL THEORY – STEM CELLS Stem cells are a large focus of study in today’s biomedical world. “They are cells that exist in an undifferentiated state‚ and transform into differing tissue types depending on what the cells surrounding them are‚“ (National Institute of Health‚ 2012). Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition‚ they also serve as an internal repair mechanism inside many tissues‚ dividing without

The cell functions much in the way a city does. Although it may be an old analogy‚ it may be one of the best. Following is a list of cell parts and how their function is similar to functions of a city or town. The cell membrane is the city limits of our city. Outside of the city limits‚ the local government has no jurisdiction‚ but inside those limits‚ people are subject to the “laws of the land”. The nucleus – This is the place where direction is given and DNA is sent from. This would

DETERMINATION OF THE WATER POTENTIAL OF POTATO TUBER CELLS. Method. Five sucrose solutions with varying molarity and one control containing distilled water were prepared and poured into test tubes. The potato discs were dried‚ weighed and added to the test tubes. The discs were then weighed again after a period of 24 hours. The percentage change in mass was then calculated. Apparatus.  Specimen tubes with stoppers x6  1cm3 diameter cork borer  razor

Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? The main function of cellular respiration is to generate ATP for cellular work; it is the process of harvesting chemical energy from organic fuel and converting it to ATP energy. The three stages of cell respiration include: Glycolysis‚ Citric Acid Cycle‚ and Electron Transport(Simon‚ Reece‚ & Dickery‚ 2010). • What is the role of glycolysis
