Discussion

13025.	Question : Plasmolysis will occur when the cell isplaced in _________solution
Answer» HYPOTONIC HYPERTONIC ISOTONIC hypotonic and isotonic

Discussion

13026.	Question : Plasmolysis is possible in plant cell while not possible in animal cell.
Answer» SOLUTION :If PLANT cell and animal cell both are put in Hypertonic solution then exoosmosis occurs in plant cells and cytoplasm separates from cell wall and shrinks and gathers in any angle of the cell but there is no cell wall in animal cell. So cell itself shrinks when water comes out from cytoplasm and this process is continued for LONG time and cell itself DIES.

Discussion

13028.	Question : Plasmolysis and deplasmolysis

13039.	Question : Plaque stimulates/causes formation of blood clot in the wall of artery.
Answer» Solution :HIGH blood pressures, smoking, excessive fatty foods etc. dimages endothelium. Plaque is BUILTIN such INJURED part due to depostion of fatty MATERIALS. First of all injured cells frow. Then unstriated muscles under endothelium associate with it. Most lipid and cholestrol get accumulated in it. This plaque arranged as processes in arteries. This provides resistance/ obstruction in blood CIRCULATION .
