Geophytic is a term that is used to describe plants that have an underground storage organ such as a bulb, corm, or tuber. Synonyms for geophytic include bulbous, tuberous, and cormous. These terms are used to describe different types of underground storage structures in plants. A bulb is a short stem with fleshy leaves that stores food, while a corm is a short, thickened stem that stores nutrients. A tuber is a swollen, underground stem that can multiply to form new plants. These different types of geophytes are important adaptations that plants use to survive in environments with harsh growing conditions such as drought, fire, or extreme temperatures.
