The sky is blue because light scatters off the atmospheric gasses. Light scatter more strongly at the blue end of the the visible spectrum then red.So, looking away from the sun into the sky you see more blue than other colors.
Plasmolysis. Plasmolysis is the contr action of cells within plant s due to the loss of water through osmosis. It is the cell membrane peeling off of the cell wall and the vacuole collapsing. Plasmolysis occurs when a plant cell 's membrane shrinks away from its cell wall. Plasmolysis is an effect of osmosis in plant s. Osmosis is the net diffusion of water across a selectively permeable membrane, such as a cell membrane, from an area of higher water concentration to an area of lower water concentration. Contents ... plasmolysis. shrinking of cytoplasm in a living cell caused by loss of water.
A plant or animal cell when kept in isotonic solution, no change is seen in their shape. The cells swell up in hypotonic solution due to endosmosis and may burst as seen in case of an animal cell.However, the protoplast shrinks away from the cell wall in plant cell (plasmolysis) when kept in hypotonic solution.Similarly the shrinkage of an animal cell is called crenation.TYPES OF SOLUTIONS Isotonic If the osmotic pressure of a solution in which a cell is placed is equal to its cell sap, it is isotonic solution. For example, parasites in our body as Plasmodium in RBC.imilarly the shrinkage of an animal cell is called crenation.
