Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name‚ (also spelled "eucaryote‚") which comes from the Greek word referring to the nucleus. Animals‚ plants‚ fungi‚ and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the

Identification of the Marker Enzymes Present in Different Fractions of a Chicken Liver Cell Priscilla Mariel M. Cadiz Biology Department‚ De La Salle University‚ 2401 Taft Ave‚ Manila‚ Philippines *Email: cadizpriscillamariel@yahoo.com Cell Fractionation allows the organelles to be studied in more depth and detailed. It is an important technique in Cell Biology because it enables to obtain precise information about the different structure and functions of the organelles. Certain organelles

Indicate whether each of the following statements about triglycerides is true or false. Indicate whether each of the following statements about triglycerides is true or false. 1. A triacylglycerol is composed of 3 glycerol molecules joined to a fatty acid. 2. The hydrocarbon chains of fatty acids vary in length as well as in the number and location of double bonds between the carbon atoms. 3. Fatty acids with one double bond in their hydrocarbon chain are called monounsaturated‚ while those with

Unit II Test Review Chapter 4 BB Notes Cells Under the Microscope Cells are microscopic in size. Although a light microscope allows you to see cells‚ it cannot make out the detail that an electron microscope can. The overall size of a cell is regulated by the surface-area-to-volume ratio. 4.2 The Plasma Membrane The plasma membrane of both prokaryotes and eukaryotes is a phospholipid bilayer. The phospholipid bilayer regulates the passage of molecules and ions into and out of the cell. The

example; in a plant cell they have a nucleus‚ mitochondria an ER‚ and a Golgi body. These are the same as animal cells; however they differ because plants cells have a cellulose cell wall‚ chloroplasts‚ large central vacuole and they use starch for storage whereas an animal cell has lysosomes‚ rough ER‚ smooth ER and ribosomes. Eukaryotes differ from prokaryotes because prokaryotes have no nucleus‚ they just have a loop of DNA and they also have no membrane-bound organelles. Prokaryotes also have a cell

M4A1 Midterm Essay BIO110 Excelsior College 1. You are the biologist in a group of scientists who have traveled to a distant star system and landed on a planet. You see an astounding array of shapes and forms. You have three days to take samples of living things before returning to earth. How do you decide what is alive? If three days is all I have to take samples of living things‚ then it would be very hard to determine what is truly alive‚ as the time restriction only allows for certain

CELLS All living things are made of cells‚ and cells are the smallest units that can be alive. Life on Earth is classified into five kingdoms‚ and they each have their own characteristic kind of cell. However the biggest division is between the cells of the prokaryote kingdom (the bacteria) and those of the other four kingdoms (animals‚ plants‚ fungi and protoctista)‚ which are all eukaryotic cells. Prokaryotic cells are smaller and simpler than eukaryotic cells‚ and do not have a nucleus. Prokaryote
