There are several ways fossil plants form. One process, called "permineralization," can occur when a plant is covered by sediment. Over time, water seeps into the pores and cells of the plant and deposits the minerals it carries. The cell walls of the plant are not replaced by minerals as the cell walls of petrified wood are. Permineralization can produce extremely detailed fossils.
What happens to the pores and cells of a plant in this process?
