Porifera Anatomy Facts

Body Wall
The integument of the body, formed of the ectoderm, consisting of epidermis, cuticula, and basement membrane.

Cell Body
The part of a neuron that coordinates information-processing tasks and keeps the cell alive.

Sponge Collar
It traps food particles.

Collar Cell
A cell that has a flagellum that moves to create currents of water which flow into the sponge.

Flagellum
A long cellular appendage specialized for locomotion and like motile cilia, eukaryotic flagella have a core with 9 outer doublet microtubules and 2 inner single microtubules ensheathed in an extension of the plasma membrane, and prokaryotic flagella have a different structure.

Osculum
Water and waste materials are expelled from the sponge through this mouth-like opening at the top.

Ostium
Pores made by choanocytes beating their flagella and drawing water into the sponge.

Spicule
Spike-shaped structure that makes up the skeletons of harder sponges, and were made of either chalklike calcium carbonate or glasslike silica.

Pinacocyte
A thin, flattened type of cell that lines the outer surface of sponges and most inner surfaces not lined by choanocytes.

Amebocyte
In sponges, an amoebalike cell that moves through the body cells, supplying nutrients, removing wastes, and transporting sperm during sexualreproduction.

Water Flow
A movement processes of the earths water, including evaporation, precipitation, and overland flow.

Porocyte
Cylindrical, tubelike cell have a pore in the middle of the cell can regulate the opening and closing of pore reverse flow to clear out pores.

Eukaryotic cells (from the Greek for true nucleus) have linear structures of DNA called chromosomes; these are found in the cell’s nucleus, which is separated from the cytoplasm by a nuclear membrane. The DNA of eukaryotic chromosomes is consistently associated …

This characteristic forms the basis of classification of Eubacteria. They are mainly classified as either Spherical Eubacteria also known as the cocci, spiral or helically-shaped Eubacteria (Spirilla), or rod-shaped Eubacteria (bacilli) . Morphology; Eubacteria are unicellular Prokaryotic cells with a …
