plasmas

The term biomembrane is used to describe the plasma membrane (cell membrane) and the membranes that surround the various cell organelles. The plasma membrane forms a protective covering around the cell to maintain its size and shape. In addition, it is also responsible for ..

Excessive loss of blood is prevented from the cut blood vessels by the formation of clots. This process is also called coagulation. The steps involved in clotting of blood are: Damaged platelets secrete thromboplastin or thrombokinase . Thrombokinase is an enzyme that changes prothrombin (present i..

Three types of cells are found suspended in the plasma of blood. They are: erythrocytes (RBC), leukocytes (WBC) and thrombocytes (Platelets). Erythrocytes (red blood corpuscles) are spherical or oval cells that are responsible for the oxygen carrying capacity of blood. The RBC are charact..

If a plant cell is placed in a highly concentrated sugar or salt solution (i.e., hypertonic solution), water from the cell sap flows out due to exosmosis through the plasma membrane outside the cell. The loss of water from the cell sap causes contraction or shrinkage of the protoplast. Si..

At the capillary end of the arteries, the walls are only one-cell thick. The pressure in the arterial capillaries is also quite high. These leads the plasma to leak into the interstitial space. The interstitial space is the space between the cells of the tissue. The fluid is plasmah..

Plasmolysis - If a plant cell is placed in a highly concentrated sugar or salt solution (i.e., hypertonic solution), water from the cell sap flows out due to exosmosis through the plasma membrane outside the cell. The loss of water from the cell sap causes contraction or shrinkage of the ..

The term cytoplasm can be used to describe the matrix of a cell found between its plasma membrane and the nucleus. It encloses various cell organelles and inclusions. The cytoplasm is a semi viscous jelly-like substance. It consists of an aqueous, almost transparent structureless ground s..

The term multiple allele is a condition where more than two genes occupy the same locus, on the same pair of homologous chromosomes, in different organisms. Each of these genes expresses a totally different character. The inheritance of A B O blood groups in man is an example of multiple alleles. ..
