Plant cell walls are rigid membranes on the outermost part of the cell. The cell wall provides a structured shape for the cell, helping the cell retain its form and shape. The cell wall also controls the rate of replication, allowing plant cells to replicate at a much slower rate than animal cells.
The light needed for photosynthetic reactions tends to be more reds and purple wave lengths. The Green wavelength is reflected. Filtering out the green light will stunt the light reactions of the plant.
