Choanocytes

Back 9

specialized cell in sponges that uses a flagellum to move a steady current of water through the sponge. The morphology of a choanocyte is extremely similar to that of a choanoflagellates

Front 10

Cnidocytes orNematocytes

Back 10

stinging cells located along the tentacles of cnidarians; used for defense and to capture prey. The nematocytes house a nematocyst.

Ganglion (pluralganglia)

Back 13

A cluster of nerve cell bodies

Front 14

Diffuse nervous system

Back 14

In diffuse systems nerve cells are distributed throughout the organism, usually beneath the outer epidermal layer. Large concentrations of nerve cells—as in the brain—are not found in these systems, though there may be ganglia, or small local concentrations of neurons. Diffuse systems are found, for example in in cnidarians

Front 15

Lophophore

Back 15

a crown of ciliated tentacles that function in feeding

Front 16

Malphigian tubules

Back 16

A unique excretory system of insects, that empties into the digestive track that removes nitrogenous wastes from the hemolymph and function in osmoregulation (allows wastes to be excreted and H₂0 to be reabsorbed)

Front 17

Mandibles

Back 17

One of a pair of jaw-like feeding appendages found in myriapods, insects, and crustaceans.

Front 18

Mantle cavity/mantle

Back 18

A water-filled chamber that houses the gills, anus, and excretory pores of a mollusk (רכיכה).

Front 19

Mesohyl

Back 19

a gelatinous region between the two layers of cells of a sponge

Front 20

Metanephridia(singular Metanephridium)

Back 20

An excretory organ found in many invertebrates that typically consists of tubules connecting ciliated internal openings to external openings (it has a kidneys function)

Front 21

Nematocysts

Back 21

In a cnidocyte of a cnidarian a capsule-like organelle containing a coiled thread that when discharged can penetrate the body of a prey and inject a toxin. האורגנלה בצורבים שעוקצת

Osculum

Back 22

A large opening on a sponge through which filtered water is expelled

Front 23

Planarians

Back 23

These are free living freshwater flatworms

Front 24

Polyps

Back 24

The sessile variant of the cnidarian body plan. The alternate form is the medusa.

Front 25

Protonephridium(plural Protonephridia)

Back 25

An excretory system such as the flame bulb system of flatworms, consisting of a network of tubules lacking internal openings.

Tracheal system

Back 28

A gas exchangesystem of branched, chitin-lined tubes that infiltrate the body and carryoxygen directly to cells in insects

Front 29

Trochophore

Back 29

The small,free-swimming, ciliated aquatic larva of various lophotrochozoan invertebrates,including certain mollusks and annelids.
