A single unit of the perianth is called ____.
-
monoecious
-
tepal
-
dioecious
-
neuter
B
Correct answer
Explanation
When sepals and petals are indistinguishable, individual perianth units are called tepals (as in tulips and lilies). This contrasts with flowers having distinct calyx (sepals) and corolla (petals). Monoecious and dioecious describe plant sexuality, not perianth parts.
