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.
The primary and secondary cell walls serve as the outer covering of the plasma membrane, while the middle lamella acts as the intermediate partition between two adjacent plant cells. Describe the role of the plasmodesmata in plant cell communication. Plasmodesmata form cytoplasmic channels, lined by membranes, that allow the cytoplasm of one plant cell to run continuously into an adjacent cell. Plasmodesmata unify an entire plant, generating linkages among all the cells. Cytoskeletal structures at the sites of the plas-modesmata guide large molecules towards the channels, facilitating their entry into adjacent cells.
