monocarpic plant
Học thuậtThân thiện
Definition
Noun: A plant that completes its entire life cycle—from germination through flowering and seed production—only once before dying. This reproductive strategy is characterized by a single, often massive, flowering event followed by the plant's death.
Usage
This term is used in botany and horticulture to classify plants based on their reproductive life history. It describes a specific biological strategy. - The century plant is a classic example of a monocarpic plant, flowering spectacularly after decades of growth. - Many biennials, like carrots, are monocarpic plants; they grow vegetatively in the first year and flower, set seed, and die in the second.
Advanced Usage
- Semelparity: This is the broader biological term for the reproductive strategy of an organism that reproduces only once in its lifetime. A monocarpic plant is a semelparous organism.
- The antonym is polycarpic, describing plants that flower and set seed many times over their lifespan without dying, such as apple trees or rose bushes.

Related Concepts
- Annual: A plant that completes its life cycle in one year. All annuals are monocarpic, but not all monocarpic plants are annuals (e.g., some live for many years before flowering once).
- Biennial: A plant that typically takes two years to complete its life cycle, flowering and dying in the second year. Biennials are monocarpic.
- Perennial Monocarp: A plant that lives for many years (perennial growth habit) but flowers only once at the end of its life, then dies. Bamboos and some agaves are examples.
