Unit 13‚ task 1. P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny‚ three dimensional sac which is in fact made up of many components‚ each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own‚ individual function which helps a cell to function and maintains the

Observing Various Cells Under The Microscope Chapter 6 Lillian Hayner Biology 211 Lab section 14 New Mexico State University Elodea Wet Mount If cytoplasmic screening is occurring‚ you will see the chloroplast circulating around the cell. Cytoplasmic streaming is controlled by microfilaments in the cell’s cytoskeleton. These filaments of actin and myosin move cellular contents in an active process that uses energy released by breaking ATP down in ADP. How might a cell benefit by

According to Reece et al. (2015)‚ animals can be described as organisms that are multicellular‚ heterotrophic eukaryotes that have tissues made from embryos. The difference between plants and animals are from their source of nutrients. Plants get their food by making them through a process called photosynthesis‚ which makes plants an autotroph. Animals‚ on the other hand‚ get their food by consuming other organisms and ingesting them‚ which makes them a heterotroph. Besides that‚ there are also variations

Name: Mugabe Rodrigue Class: Grade 11B Subject: Biology Topic: DNA Extraction From Onion Date: 20/1/2014 Introduction: DNA‚ or deoxyribonucleic acid‚ is the hereditary material in organisms. Nearly every cell in an organism has the same DNA. Most DNA is located in the cell nucleus.The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of these bases determines the information available for

Lab 2: Animal and Plant Cells Purpose: To examine the differences between single cell and multi cell organisms in terms of Animal and Plant cells. Question: What are the differences between multi and single celled plant and animal organisms? Prediction: Spirogyra Cell: The parts of the spirogyra cell that will be visible under the microscope will be; cell wall‚ cell membrane‚ nucleus‚ chloroplasts‚ vacuole and cytoplasm. Banana Cell: The parts of the banana cell that will be visible

A Human Is A Complex Organism Human beings are complex and special organisms as there is a complex organisation of cells in the human body. The organisation in the human body is summarised as follows: Cells—> Tissues—> Organs—> Systems—> Organism.The same type of cells which carry out a specific function are organised into a tissue. For example‚ a group of nerve cells form a nerve tissue. They are organised to work together to perform specific functions as the result of cells in the human body

Abstract Western blotting is an analytic technique used around the world for many reasons; detecting infections‚ diseases‚ and particular proteins in a tissue. When western blotting‚ first the proteins are extracted and undergo Gel Electrophoresis‚ next it goes through elecroblotting‚ and finally detects the proteins. When the results after every step is completed‚ the membrane is analyzed based on where the bands are present in the gel. It has been told that actin and myosin is present in fish

FORMATION OF THE ASCOPORES IN THE ASCOMYCOTINA In a typical ascomycotina‚ pyronema for example‚ sexual reproduction is by gametangial contact invoving the ascogonium ( female organ) and antherridium (male organ). Ascus and ascopores are results of sexual reproduction . the female and male organs aare produced by the mycelium. A trichogyne is also produced which joins the antheridium to the ascogonium. The content of the antheridium passes into the ascogonium through the trichogyne. The ascogonium
