Transparency water column: here, a relative measure indicates the water transparency (transparency/depth), in which it is assumed that positive photosynthesis of water plants is not possible if transparency (Secchi) is roughly half the water depth, corresponding with a 3% light reduction to the soil. Soil light penetration is essential to Charales because of their low growth. |
