Having two pores or pore-like openings.
From bi- (two) + porous (from Latin porus, a pore or opening). This is a technical biological or botanical term created to describe structures with exactly two openings.
Plant scientists use terms like 'biporose' to describe things like pollen grains that have exactly two pores instead of three or many—it's a tiny detail, but it helps them identify and classify plants with scientific precision.
