Why leaves are said to be excretophores?
Leaves are said to be excretophores because in the uptake of nutrients delivered from soil through root tips, through stems and into the leaf, nutrients become part of the leaf. Having absorbed the nutrients, the leaf develops by way of photosynthesis. Having developed and having remained attached to the plant for awhile, the leaf detaches from the plant, (or is excreted) taking the ingested nutrients (that may even include contaminants) with it as it falls from the plant.
