- ice (n.)
- The frozen form of water. Because ice has a specific gravity
(0.92) less than water, ice floats on water.
- immigration (n.)

- imperfect flower (n.)
- A flower which lacks either stamens or carpels.
- inbreeding (n.)
- In plants, a breeding system where sexual reproduction involves the

- inflorescence (n.)
- The way that a plant arranges its flowers on an axis or stem.
- inhibition model of succession
- A model of succession that suggests that changes in the dominance of
plant species with time is due to:
- death and small-scale disturbances;
- variations in longevity of plant species; and
- variations in ability of species to disperse.
- Species turnover favors species with longer life spans.
- inorganic (adj.)
- Something non-living, particularly the physical and chemical
components of an organism's environment. (Also
- invasive (adj.)
- Any plant that grows so aggressively that it crowds out other plants.
Often applied to non-native species.
- involucre (n.)
