What is Cell Lysis? 10 hilariously insightful foreign words. Cell lysis is a process in which a cell is broken down or destroyed as a result of some external force or condition. Lysis can happen through natural means, such as viral infections, or through artificial means for research purposes.

- Important vocabulary - higher tier. 1  Lysis – bursting an animal cell by osmosis. 2  Crenation – shrinking an animal cell by osmosis. 3  Turgid – a plant cell fully inflated with water. 4  Plasmolysed – a plant cell that has lost water causing the cell membrane to be pulled away from the inside of the cell wall.

- If a cell is placed into a hypotonic solution, the water will flow into the cell causing it to swell and possibly lyse. If a cell is placed into a hypertonic solution, the wat … er will flow out of the cell causing it to crenate. So hemolysis occurs when the red blood cells lyse.

What are the steps of the lytic cycle? 1 This is how the lytic cycle got its name. 2  Once the host cell is lysed, a huge number of new viruses are released into the inter cellular spaces of the host. 3  The new viruses are then free to attach to and infect other cells in the same host, or to shed from the first host and infect others.

- LINK / CITE ADD TO WORD LIST. noun. The definition of lymph is a clear or yellow liquid that contains white blood cells and is found between cells in the body. An example of lymph is a fluid that moves bacteria away from an inflammed body part.

Lysis For example, lysis is used in western and Southern blotting to analyze the composition of specific proteins, lipids, and nucleic acids individually or as complexes. Depending upon the detergent used, either all or some membranes are lysed.ysis in the laboratory may be effected by enzymes or detergents or other chaotropic agents. Mechanical disruption of cell membranes, as by repeated freezing and thawing, sonication, pressure, or filtration may also be referred to as lysis.

Lymphocytosis Definition. Lymphocytosis (lim-foe-sie-TOE-sis), or a high lymphocyte count, is an increase in white blood cells called lymphocytes (LIM-foe-sites). Lymphocytes are an important part of the immune system.They help fight off diseases, so it's normal to see a temporary rise in the number of lymphocytes after an infection.A count significantly higher than 3,000 lymphocytes in a microliter of blood is generally considered to be lymphocytosis in adults.ymphocytes are an important part of the immune system.

lysis [lī′sis]. Etymology: Gk, lysein, to loosen. 1 destruction or dissolution of a cell or molecule through the action of a specific agent. Cell lysis is frequently caused by a lysin. lytic, adj. 2 gradual diminution in the symptoms of a disease. Compare crisis. 3 surgery performed to free adhesions of tissues.

- B cell. Any of the lymphocytes that develop into plasma cells in the presence of a specific antigen, such as a bacterium or virus. The plasma cells then produce antibodies that attack or neutralize the antigen. B cells mature in the bone marrow before being released into the blood.

lymph Lymph. The almost colourless fluid that bathes body tissues and is found in the lymphatic vessels that drain the tissues of the fluid that filters across the blood vessel walls from blood.Lymph carries antibodies and lymphocytes (white blood cells that help fight infection) that have entered the lymph nodes from the blood.hen this fluid is drained from the tissues and collected by the lymphatic system, it is called lymph. The lymphatic system eventually returns the lymph to the blood, where it again becomes plasma. This movement of fluid through the body is described under circulatory system.

- When a blood sample is hemolyzed, it means the red cells have ruptured to the extent that they impart a pink/red color to the blood plasma, which is normally pale yellow. By comparison, gross hemolysis describes a plasma sample as intensely red as cherry-flavored gelatin.The red color is due to hemoglobin.hen a blood sample is hemolyzed, it means the red cells have ruptured to the extent that they impart a pink/red color to the blood plasma, which is normally pale yellow.

Lymphocyte Count Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Definition (NCI_NCI-GLOSS). A type of immune cell that is made in the bone marrow and is found in the blood and in lymph tissue. The two main types of lymphocytes are B lymphocytes and T lymphocytes. B lymphocytes make antibodies, and T lymphocytes help kill tumor cells and help control immune responses. A lymphocyte is a type of white blood cell. Definition (NCI). White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules.

Syphilis Syphilis is transmissible by sexual contact with infectious lesions, from mother to fetus in utero, via blood product transfusion, and occasionally through breaks in the skin that come into contact with infectious lesions.rimary syphilis is characterized by the development of a painless chancre at the site of transmission after an incubation period of 3-6 weeks. The lesion has a punched-out base and rolled edges and is highly infectious.

Chapter 13: Meiosis a display of condensed chromosomes arranged in homologous pairs. Isolated somatic cells are treated with a drug to stimulate mitosis, grown in culture for several days, arrested in metaphase, & stained to organize. Used to screen for abnormal #s of chromosomes or defective chromosomes.

- An electrolytic cell is an electrochemical cell that undergoes a redox reaction when electrical energy is applied. It is most often used to decompose chemical compounds, in a process called electrolysis—the Greek word lysis means to break up. When electrical energy is added to the system, the chemical energy is increased. Similarly to a galvanic cell, electrolytic cells usually consist of two half cells. Important examples of electrolysis are the decomposition of water into hydrogen and oxygen, and bauxite into aluminium and other chemicals.

T cell T cell, n a small, circulating lymphocyte produced in the bone marrow that matures in the thymus. T cells primarily mediate cellular immune responses, such as graft rejection and delayed hypersensitivity.

This will occur if the cells are placed in plain water. the rupturing of a cell with release of its contents; for example, the bursting of a bacterial cell to release BACTERIOPHAGES, or HAEMOLYSIS - the bursting of a red blood cell (see RHESUS HAEMOLYTIC ANAEMIA).

Concept 2 Review Hypotonic. When a cell is exposed to such hypotonic conditions, there is net water movement into the cell. Cells without walls will swell and may burst (lyse) if excess water is not removed from the cell.
