Where is mesoglea found?
Mesoglea refers to the tissue found in cnidarians like coral or jellyfish that functions as a hydrostatic skeleton. It is related to but distinct from mesohyl, which generally refers to tissue found in sponges.
What is mesoglea where is it found in coelenterates?
The mesoglea layer, which lies between the ectoderm and the endoderm (the innermost tissue layer) of coelenterates, is thin in small species and massive in large ones. It forms a flexible skeleton, associated with supporting muscle fibres on both the ectodermal and endodermal sides.
Is mesoglea present in Coelenterata?
Mesoglea is prese All coelenterates are aquatic animals.
What cells are found within mesoglea?
They consist of two body layers derived from the endoderm (gastrodermis) and ectoderm (epidermis) of the embryo. Between these two cellular layers is an amorphous, jelly-like mesoglea connective layer. This generally contains no cellular elements other than some scattered amoebocytes and local genital cells.
Is mesoglea present in Cnidaria?
A Anatomy and Physiology All freshwater cnidarians have a radially symmetrical, two-cell layer, tubular body separated by a thin noncellular layer called the mesoglea. Their combined mouth–anus structure is ringed with outwardly projecting tentacles containing stinging cells (nematocysts).
Are cnidarians intracellular or extracellular?
Cnidarians perform extracellular digestion, with digestion completed by intracellular digestive processes. Food is taken into the gastrovascular cavity, enzymes are secreted into the cavity, and the cells lining the cavity absorb the nutrient products of the extracellular digestive process.
What is mesoglea in zoology?
Definition of mesoglea : a gelatinous substance between the endoderm and ectoderm of sponges or cnidarians.
What is mesoglea in biology class 11?
Explanation: Hint: Mesoglea is a translucent, jelly-like, non-living substance. It is found in diploblastic animals (which have only two true layers) like Cnidarians and Sponges. Mesoglea is present between the two layers of the diploblastic animals.
What is mesoglea quizlet?
Mesoglea. A non-living gelatinous layer in between the epidermis and the gastrodermis that contain living cells derived from embryonic ectoderm such as amoebocytes.
