Asconoid syconoid and leuconoid are all examples of what?
sponges
Where is collar cell found?
Choanocytes (also known as "collar cells"). Choanocytes are found dotting the surface of the spongocoel in asconoid sponges and the radial canals in syconoid sponges, but they comprise entirely the chambers in leuconoid sponges.
What are 2 other phyla members of a jellyfish?
asconoid sponges, and syconoid
3 characteristics of sponges?
there are really many types of sponges. One is the octopus sponge people love this kind because it contians a lot of fluid inside it. Another type is the seahorse sponge with is huge and it can bite through a shark. it is the size of two elephants! one more sponge is the lily pad sponge it is a light green with the smell of frog on it, it doesnt smell nice and it eats dolphins which IS MEAN!
What body plan do phylum porifera aka sponges have?
It has no symmetry, and they have jelly like cells that transport food throughout the body. Collar Cells: fires spines that traps food. Spiky things: Protects the Sponges's body.
What is the largest class of sponges and what is its body type?
The largest class of sponges is Demospongiae, which includes over 90% of all known sponge species. Their body type is typically characterized by a leuconoid structure, which consists of a complex network of canals and chambers that allows for efficient water flow and filtration.
What is Order Clathrinida?
(kla′thrin·ə·də)(invertebrate zoology) A monofamilial order of sponges in the subclass Calcinea having an asconoid structure and lacking a true dermal membrane or cortex.
What adaptations do phylum porifera have that are unique?
Unique stuctures of Phylum Porifera include 1 : Spicules which may be calcarious or silicious . 2 : Canl system , which may be asconoid , syconoid or leucon type . 3 Spongin fibers in some fresh water sponges .
Do sea sponges have a diploblastic or triploblastic body organization?
spoges are diploblastic because they have radial symmetryone's having rad. sym. are diplo.and one's having bilateral are triploblasticThis is a true statement, but what we find in animal biology is that there are exceptions to most of the rules. Sponges, or the phylum Porifera do not have true tissues. They are metazoa at their cellular grade of construction, not eumetazoa. If you look at phylogenic tree, you will see that sponges are not directly related to cnidarians, which are radial symmetric and diploblastic. Some sponges are radial symmetric, however the class of sponges, demospongiae, have many species of sponges which have leuconoid body-plans, which are asymmetrical. These are mostly freshwater sponges. So therefore, sponges are not triploblastic or diploblastic, they are neither since they possess no true tissues.
What sponge body type is most efficient and makes the largest body size?
Sponges have a single body cavity known as the spongocoel . The spongocoel is critical to the food gathering strategy of sponges.
What is the grantia canal system?
The Grantia Canal System is called the "Sycon (syconoid) Canal System." This means that the canals from the sponges inside (excurrent canals) and those from the outside (incurrent canals) of its body wall end blindly, but are connected at right angles by openings called prosopyles. This type of canal system is intermediate in canal complexity. The canals are the pathways the water takes through the sponge.
Are sea sponges decomposers?
No, sea sponges are not decomposers. Sponges are filter feeders.
