floral organ primordia

Show Summary Details

Quick Reference

Meristematic cells that give rise to the organs of flowers. The primordia are arranged into four concentric whorls as shown on page 162. The leaf-like sepals form whorl number 1 at the periphery. The showy petals form whorl 2, inside the first. The stamens, the male reproductive organs, form whorl 3 (inside whorl 2), and the carpels, the female reproductive organs, form central whorl 4.
