Velamen tissue is a specialized layer of cells found in the roots of some epiphytic plants, such as orchids. Its main functions include absorbing and storing water and nutrients from the surrounding environment, as well as providing protection against desiccation and external damage. The velamen tissue is distinctive for its spongy texture and ability to regulate water uptake in these unique plant species.

What is the function of velamen in epiphytic plants?
Velamen is a specialized tissue found in the aerial roots of epiphytic plants, such as orchids. Its primary function is to absorb moisture and nutrients from the surrounding air and rainwater, helping the plant thrive in its often nutrient-poor, humid environment. The velamen also provides protection against desiccation and harsh environmental conditions, allowing the plant to maintain hydration and support its growth.
Where do orchids roots absorb water?
Orchid roots absorb water through specialized structures called velamen roots, which are located on the outer surface of the roots. These roots are covered with a spongy tissue that helps in absorbing moisture from the air and surrounding environment, rather than directly from the soil.
What kind of tissue is transitional tissue?
Transitional tissue is a type of epithelial tissue.

What is a velamen?
A velamen is a specialized layer of tissue found in the aerial roots of certain epiphytic orchids and other plants. It serves primarily as a protective covering that helps in moisture absorption and gas exchange. The velamen is typically spongy and porous, allowing the plant to efficiently take up water and nutrients from the humid air and surrounding environment. This adaptation is particularly beneficial in their natural habitats, which often have fluctuating moisture levels.
What is a fascicle A velamen?
A fascicle is a bundle of structures, typically referring to a group of muscle fibers, nerve fibers, or vascular bundles in plants. In botanical terms, it can also describe a cluster of flowers or leaves. A velamen, on the other hand, is a specialized spongy tissue found in the roots of certain epiphytic orchids, which helps in water absorption and protects the root from desiccation. Together, these terms illustrate the diversity of structures in both animal and plant biology.
How do plants get water to sustain them?
In most of the cases through endo-osmosis by root hairs; in Orchids through velamen cells.
Where do orchids roots absorb water?
Orchid roots absorb water through specialized structures called velamen roots, which are located on the outer surface of the roots. These roots are covered with a spongy tissue that helps in absorbing moisture from the air and surrounding environment, rather than directly from the soil.
Four types of human tissue?
The four main types of human tissue are epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue covers body surfaces and lines cavities. Connective tissue supports and connects various body parts. Muscle tissue is responsible for movement, while nervous tissue transmits and processes information in the body.
