difference between an animal cell and a bacterial cell is a bacterial cell contains a plasmid‚ a ring of DNA‚ opposed to the chromosomes that animals possess. There are a few other differences‚ such as size and whether or not they contain membrane bound organelles‚ which bacteria do not. Bacterial cells are much smaller than animal cells. PART B Lab Questions: This procedure is used to separate what two types of bacteria? Gram Stain This separation is based on differences in what physical trait? The structure

to gather the materials‚which include gelatin packs‚ plastic bags‚ water‚ Tupperware‚ bowls‚ and some small various householditems. The other objectives are preparing the gelatin as directed‚ gathering the household items that willserve as cell organelles‚ pouring the gelatin in the bag and placing the items in the plastic bags. Thenplace the cell replicas in the refrigerator for 24 hours.MethodsFirst‚ I turned on the stove to heat the three cups of water to boiling. While waiting on the water to

Cell Fractionation * Cell Fractionation: takes cells apart and separates the major organelles and other subcellular structures from one another. * Tissue cells are the first one to be homogenate or broken apart. * Plasma membranes are broken up so that there internal contents spill out and mix together and this is called homogenate. * Homogenate is in spun in a higher rate of speed in a process called centrifugation. And that speed can vary that why it’s called differential

Mediterranean‚ the Atlantic coast of Europe‚ the Near East‚ andIndia. A second wild subspecies‚ Beta vulgaris subsp. adanensis‚ occurs from Greece to Syria. Beetroot cells like any other eukaryotic cells have many types of cell organelle present. Some of these organelles are bounded by a single membrane‚ e.g. lysosomes‚ Golgi apparatus‚ vacuoles; some are bounded by two membranes (an envelope)‚ e.g. nucleus‚ mitochondrion. Beetroot appears as a dark red/ purple colour and this is caused by the betalain

Cristina Alzandua General Biology 1401 Dr. Erin Schuenzel February 13‚ 2014 Bacterial and Eukaryotic Cell Structures All organisms are composed of cells which are characteristically microscope in size. Cell size is limited by the efficiency of diffusion across the plasma membrane. A typical eukaryotic cell is 10 to 100 micrometers in diameter opposed to prokaryotic cells are 1 to 10 micrometers in diameter. Bacterial and Eukaryotic cells display different cell organization in their size and

Cells are some of the smallest organisms around. All living things consist of cells‚ and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly. All cells are separated from their surrounding by a cell membrane. The cell membrane regulates what enters and leaves the cell and also aids in the protection and support of the cell. A cell membrane

Imagine a busy factory making the latest must-have toy. Whether they make bicycles‚ cell phones‚ or hot air balloons‚ most factories are set up the same way. All factories have outside walls that protect and support them and inside walls that create different work areas. They usually have a production line where a product is put together and an executive department that decides what product is made. A finishing department processes and prepares the product for shipping‚ and a packaging department
