Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Orchids have two main growth habits: Monopodial and Sympodial.
Step 2: Detailed Explanation:
Monopodial Growth: The plant grows from a single terminal bud (one main stem) that keeps growing indefinitely. It doesn't have pseudobulbs. Examples: Phalaenopsis, Vanda. (A is incorrect).
Sympodial Growth: The plant grows from a series of repeating units. Each new shoot arises from the base of the previous one (rhizome). These plants usually produce "pseudobulbs" (swollen stems) to store water and nutrients.
Dendrobium (B): This is a classic sympodial orchid. It grows from a rhizome and produces new stems (canes) every year.
Cymbidium (D): This is also a major sympodial orchid. It produces large, prominent pseudobulbs from a creeping rhizome.
Habenaria (C): These are terrestrial orchids. While some may show sympodial-like tuberous growth, in commercial orchid classification questions, the focus is usually on the major epiphytic groups. However, between the given options, Dendrobium and Cymbidium are the most definitive sympodial examples used in horticulture.
Step 3: Final Answer:
Dendrobium and Cymbidium exhibit sympodial growth patterns.
