Invert Exam 2 Porifera

Front 1

Sponges will reform with cells within it's own colony, this concept is called

Back 1

Isogeneic

Front 2

sponge cells from different colonies of the same species showing incompatibility is called

Back 2

Allogeneic

Front 3

Sponge Cells from different species would not form together, they are

Back 3

Allogenic as well

Front 4

Having an immune systems means

Back 4

The organism (Cells) must show a level of antagonism towards foreign substances.

The antagonism must be specific toward that substance.

Future responses should be altered by the first response. (Memory)

is the large, central cavity of sponges

Back 12

Spongocoel

Front 13

Choanocyte Functions and the kind of cell

Back 13

Collar cells
Generate current
Capture food
Capture sperm for fertilization

Front 14

is the gelatinous matrix within a sponge. It fills the space between the external pinacoderm and the internal choanoderm.

Back 14

Mesohyl

Front 15

Archaeocyte function

Back 15

Digestion & removal of waste

Store food

Give rise to flagellated sperm and eggs

Non-self-recognition

Secrete supportive elements

Front 16

Spicules function

Back 16

Calcareous, siliceous, or composed of

collagenousproteins (spongin)

Function: Maintain shape and Discourage predation

Front 17

Spicule Producers

Back 17

Archaeocytes -> Sclerocytes -> (Calcium/silica)

Spongocytes -> Spongi

Front 18

Pinacocyte function and descriptions

Back 18

Pinacocytes – Flattened contractile cells

-> Pinacoderm

Ostia – Openings in the porocyte for water entry

Osculum – Openings for water exiting from spongocoel

Class Calcarae

Back 25

Calcium Carbonate Spicules

Members span all 3 types of architecture

Asconoid sponges are found only here

All Marine

EXAMPLE- GRANTIA

Front 26

Class Demospongiae

Back 26

Largest class (80% of all sponges)

Silica Spicules, never calcium carbonate

Have Spongin Fibers

ALL FRESHWATER SPONGES FOUND HERE

FAMILY CLIONIDAE AND SPONGIIDAE (Encrusting and boring sponges)

Front 27

Class Hexactinellida

Back 27

Supported by 6-rayed siliceous spicules

CALLED GLASS SPONGES

Live in soft sediment -> spicules anchor them

Attached to solid substrate

Syncytial -> outer and inner flagellated layers

EXAMPLE- EUPLECTELA
