The Bayer filter RGB is commonly used in digital still cameras, camcorders, and scanners.  The Bayer filter pattern is 50% green, 25% red and 25% blue.   The reason there is more green is that both silicon and the human eye are most responsive around the green wavelengths. Structure vectors

Osmosis in a Plant Cell. 3 types of tonicity: hypotonic, hypertonic, and isotonic. In a hypotonic environment, water enters a cell, and the cell swells. In a hypertonic solution, water leaves a cell and the cell shrinks. In an isotonic condition, the relative concentrations of solute and solvent are equal on both sides of the membrane.
