Sponges will reform with cells within it's own colony, this concept is called |
Isogeneic |
|
sponge cells from different colonies of the same species showing incompatibility is called |
Allogeneic |
|
Sponge Cells from different species would not form together, they are |
Allogenic as well |
|
Having an immune systems means |
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) |

There is only one family of freshwater sponges found in the United States and its called |
Spongillidae |
|
The 3 different types of sponges |
Freshwater Sponges Marine Environment Deep sea |
|
The 3 different types of sponges with examples |
Freshwater Sponges- Spongillidae Marine Sponges- Encrusting Sponge Deep Sea sponges- Harp Sponge and Ping Pong Tree Sponge |
|
Harp Sponge taxonomic name |
Chondrocladia lyra
|
|
Ping Pong Tree Sponge taxonomic name |
Chondrocladia lampadiglobus |
|
The 9 Sponge Cellular Components |
Osculum Coanocyte Ostium Porocyte Mesohyal Spongocoel Spicule Pinacocyte Ostium |
|
is the large, central cavity of sponges |
Spongocoel
|
|
Choanocyte Functions and the kind of cell |
Collar cells
Generate current Capture food Capture sperm for fertilization |
|
is the gelatinous matrix within a sponge. It fills the space between the external pinacoderm and the internal choanoderm. |
Mesohyl |
|
Archaeocyte function |
Digestion & removal of waste Store food Give rise to flagellated sperm and eggs Non-self-recognition Secrete supportive elements |
|
Spicules function |
Calcareous, siliceous, or composed of collagenousproteins (spongin) Function: Maintain shape and Discourage predation |
|
Spicule Producers |
Archaeocytes -> Sclerocytes -> (Calcium/silica) Spongocytes -> Spongi |
|
Pinacocyte function and descriptions |
Pinacocytes – Flattened contractile cells -> Pinacoderm Ostia – Openings in the porocyte for water entry Osculum – Openings for water exiting from spongocoel |
|
Sponge architecture types |
Asconoid, Syconoid, Leuconoid Ascon, Sycon and Leucon for short. |
|
4 Different methods of asexual sponge reproduction |
1. Budding 2. Fragmentation 3. Stolon Formation 4. Gemmule Formation (Freshwater Sponges) |

|
Different sponge classes |
Calcarea Demospongiae Hexactinellida |
|
Class Calcarae |
Calcium Carbonate Spicules Members span all 3 types of architecture Asconoid sponges are found only here All Marine EXAMPLE- GRANTIA |
|
Class Demospongiae |
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) |
|
Class Hexactinellida |
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 |
