monoicous

Thân thiện

A single moss plant is monoicous, bearing both male and female structures.

Definition

Adjective: 1. Having both male and female reproductive organs on the same individual organism: This term is used in biology to describe a plant or animal that possesses both the male (e.g., antheridia, pollen-producing structures) and female (e.g., archegonia, ovule-producing structures) reproductive structures on a single individual. It is synonymous with "monoecious."

Usage and Examples

• Adjective:
  • Mosses are often monoicous, with both antheridia and archegonia on the same gametophyte.
  • The botanist identified the species as monoicous after observing it bore both staminate and pistillate flowers.

Advanced Usage

• In botanical taxonomy, the term is frequently applied to bryophytes (like mosses and liverworts) and some vascular plants. It describes a condition that contrasts with dioicous (where male and female structures are on separate individuals).
• The spelling monoicous is common in British English, while monoecious is more frequent in American English, though both are accepted in scientific literature.
