Pollen grains are the microscopic male reproductive particles released from flowering plants. As these grains are vital for the survival of flowering species, evolution has ensured that individual species produce different types of pollen grains. Pollen grains are also made of a resistant organic material (sporopollenin) that means they are often remarkably well-preserved in sediments many thousands of years old.
