Correct option is C
The correct answer is option (c) Epiphytes.
Explanation
The velamen is a specialized tissue found in the roots of epiphytes, particularly in plants like orchids. It is a multilayered, spongy tissue that helps in absorbing water and protecting the underlying cells. Velamen is especially useful for epiphytes, which live on other plants (like trees) and are exposed to fluctuating levels of water availability, often in tropical environments.
Information Booster
Epiphytes are plants that grow on other plants (like orchids or bromeliads) but do not parasitize them. They rely on the moisture and nutrients from the air, rain, or debris around them.
The velamen helps these plants retain water and prevent desiccation in the dry conditions of their environment.
Halophytes are plants that grow in saline environments (such as mangroves), and they do not typically have velamen cells.
Xerophytes are plants adapted to dry environments and may have other water-conserving adaptations but not velamen.
Heliofytes are plants that grow in full sunlight, but they are not specifically associated with velamen.
Additional Knowledge
Halophytes: These plants are adapted to high-salinity environments (like salt marshes or coastal areas) and do not typically have velamen cells.
Xerophytes: These plants are adapted to dry, arid conditions (such as cacti or succulents) and use different adaptations like thick cuticles and water-storing tissues, but they do not have velamen cells.
Heliofytes: These plants are adapted to sunny, open areas, but they are not specifically characterized by the presence of velamen cells.
