In actuality, however, plants do not absorb all incoming sunlight (due to reflection, respiration requirements of photosynthesis and the need for optimal solar radiation levels) and do not convert all harvested energy into biomass, which results in a maximum overall photosynthetic efficiency of 3 to 6% of total solar radiation. [1]
Except for some parasitic plants, all land plants need sunlight to survive. [1] However, in general, more sunlight does not always make it easier for plants to survive. In direct sunlight, plants face desiccation and exposure to UV rays, and must expend energy producing pigments to block UV light, and waxy coatings to prevent water loss.

The plants do not seem to sucker or produce offshoots, but from the germination of their seeds they can form small, dense clumps. The fat, wide, serrated, gray-green leaves have sharp, dark leaf-tips and grow in ...
