In which class of sponges can you find an asconoid type of canal system?
Ascon type of canal system This canal system is the simples of all the three. It is found in asconoid type of sponges like Leucosolenia and also in some of the developmental stages of all the syconoid sponges.
What is Syconoid type of canal system?
Syconoid type of canal system is the first stage above the asconoid type. It is formed by the out pushing of the wall of an asconoid sponge at regular intervals into finger like projections, called radial canals.
What are the three types of canal system?
Three main types of canal systems in the order of increasing complexity are asconoid, syconoid and leuconoid (2).
- Asconoid Canal System.
- incurrent pores which pass through porocytes into spongocoel.
- Syconoid Canal System.
- Leuconoid Canal System.
Which type of canal system is found in Leucosolenia?
asconoid type
Its canal system is of asconoid type. The colony consists of few simple vase-like, cylindrical individuals each terminating in an osculum and united at their bases by irregular horizontal tubes. Leucosolenia reproduces both asexually and sexually.
What is Rhagon type canal system?
Rhagon type, with conical shape and broad base Canal system in sponge body is a system of characteristic criss-crossing canals (water channels) for water flow that communicate to exterior through numerous apertures, the ostia and osculum. It is a characteristic feature of poriferans.
What is a Pinacoderm in sponge?
From Wikipedia, the free encyclopedia. The pinacoderm is the outermost layer of body cells (pinacocytes) of organisms of the phylum Porifera (sponges), equivalent to the epidermis in other animals.
What is the difference between asconoid Syconoid and Leuconoid sponges?
Syconoids do not usually form highly branched colonies as asconoids do. During their development, syconoid sponges pass through an asconoid stage. Leuconoid sponges lack a spongocoel and instead have flagellated chambers, containing choanocytes, which are led to and out of via canals.
What is canal system and its types?
✴Canal System is a system of passages connecting various cavities of the animal body (as in corals and sponges)…. ✴Types of Canal Systems : ⭐Ascon type, with flagellated spongocoel. ⭐Leucon type, with flagellated chambers. ⭐Rhagon type, with conical shape and broad base.
Which type of spongocoel is found in Leucosolenia?
So, the correct answer is ‘Ascon type’.
Is Leucosolenia solitary or colonial?
Most species of Leucosolenia are 2.5 centimetres (one inch) or less in length. They grow as a colony of slender individuals connected by a common stolon—i.e., a rootlike process—which also attaches the group to the bottom or to some other surface.
