HYALODERMIS Meaning and
Definition
-
Hyalodermis is a term used in biology and anatomy to refer to a specific layer of cells or tissues found in certain organisms, particularly in plants and invertebrates. The term is derived from the Greek words "hyalos," meaning glass or transparent, and "dermis," which refers to the layer of skin or tissue beneath the epidermis.
In plants, the hyalodermis is a transparent layer located just below the epidermis. It is often composed of cells that are thin-walled and highly transparent, allowing light to pass through. This layer plays an important role in the process of photosynthesis, as it helps to transmit light efficiently to the underlying cells where photosynthesis occurs.
In some invertebrates, such as certain jellyfish and other marine organisms, the hyalodermis is a layer of cells found within the outer covering or body wall. These cells are typically thin, transparent, and gelatinous in nature. The hyalodermis in these organisms serves as a protective layer, helping to shield the internal tissues from external threats while still allowing for the passage of nutrients, gases, and other substances.
Overall, the hyalodermis can be described as a transparent layer of cells or tissues that is commonly found in certain plants and invertebrates. Its primary functions include facilitating light transmission for photosynthesis in plants and providing protection for internal tissues in certain organisms.
Etymology of HYALODERMIS
The word hyalodermis derives from the combination of two Greek roots: hyalos meaning glass or transparent, and dermis meaning skin or layer.
