Texas FFA Nursery Landscape Practice Exam

Which plant grows from a tuber?

1. Impatiens

2. Japanese honeysuckle

3. Elephant Ear

4. Celosia

The correct answer is: Elephant Ear

The correct answer is that the Elephant Ear plant grows from a tuber. Tubers are specialized storage organs that serve as a means for plants to store nutrients and energy, which they can use to grow and thrive in favorable conditions. Elephant Ear (Colocasia and Alocasia species) is known for its large, attractive leaves and can be grown in various environments, typically in tropical or subtropical regions. When comparing it to the other plants listed, Impatiens are typically grown from seeds or cuttings, and Japanese honeysuckle is a climbing vine that propagates through its stems and seeds rather than tubers. Celosia, which includes the commonly known cockscomb, also grows primarily from seeds. Therefore, the unique characteristic of the Elephant Ear growing from a tuber distinguishes it from the other options presented.
