Quizplus · Accepted Answer

The durability of a leaf skeleton in nature printing is due to the tough lignified cell walls of the vascular cells. These cells, which make up the vascular tissue (xylem and phloem), are responsible for the transport of water, nutrients, and sugars throughout the plant. Their cell walls are reinforced with lignin, making them strong and resistant to decomposition, unlike the more delicate mesophyll and epidermal cells.
