Actinomorphicactinomorphic:
(adj) of flowers, having radial symmetry; capable of being bisected into identifical halves along more than one axis
(radially symmetrical) means divisible into approximately equal halves along two or more planes. Such flowers have perianthperianth:
(n) collective term for the calyx and corolla of a flower; also used for floral whorl(s) in which the calyx and corolla cannot be resolved; any of the leaves or bracts surrounding the sex organs of bryophytes
parts similar in shape and size and evenly distributed.
Zygomorphiczygomorphic:
(adj) bilaterally symmetrical; symmetrical along only one plane
(bilaterally symmetrical) means divisible into approximately equal halves along one plane only. In such flowers, perianthperianth:
(n) collective term for the calyx and corolla of a flower; also used for floral whorl(s) in which the calyx and corolla cannot be resolved; any of the leaves or bracts surrounding the sex organs of bryophytes
parts differ in shape, or size, or are not evenly spaced. Choose this state if a flower is noticeably zygomorphiczygomorphic:
(adj) bilaterally symmetrical; symmetrical along only one plane
