Anatomy Of A Sponge

Sponges are either radially symmetrical or have no symmetry asymmetrical. Anatomy the body of a sponge is a collection of a few different types of cells loosely arranged in a gelatinous matrix called a mesohyl mesoglea or mesenchyme.

Anatomy of a sponge. Morphology and canal system. Instead they consist of three cell sized layers. In the gel layer are either spicules supportive needles made of calcium carbonate or spongin fibers a flexible skeletal material made from protein.

Store digest and transport food excrete wastes secrete skeleton and also may give rise to buds in asexual reproduction pinacoderm the outer epidermal layer of cells on a sponge. Amoeba like cells found throughout the sponge. Anatomy a sea sponges body primarily consists of spicules and spongin.

Body of a sponge is vase like tubular tube like cylindrical branched cushion shaped etc. Sponges have neither tissues nor organs. Spongin is a protein that helps provide body support.

The body of a sponge has two outer layers separated by an acellular having no cells gel layer called the mesohyl also called the mesenchyme. This mesohyl is the connective tissue of a sponge body and it is supported by the skeletal elements. Spicules are needle shaped fiberlike structures that act as the sponges skeleton.

The skeletal elements of sponges are variable and important in taxonomy. Sponges are sessile not mobile organisms including both solitary and colony forming types. The cells in the outer layers can move inward and change function.

Basic anatomy sponges contain no organs or even tissue. Sponges exhibit radial symmetry. Compressed polygonal cells called pinacocytes make up the pinacoderm the external sac layer.

Sponges lack true tissues. Sponges lack a true body cavity. Sponges have a true coelom.
