What is the key characteristic of sponges?
Sponges are simple, multi-cellular organisms that lack true tissues and organs. They have a porous body with specialized cells called collar cells that help them filter and consume food particles from their environment.
What is the function of choanocytes in reproduction of sponges?
Choanocytes in sponges function in producing sperm and eggs, as well as in the development of embryos. They help to capture and process sperm in sponges that are hermaphroditic (contain both male and female reproductive organs) and assist in releasing the developing embryos for sexual reproduction.
Name some sponges?
Hexactinellida, Calcarea, Demospongiae, andSclerospongiaeTechnically, however, the Sclerospongiae are not considered sponges. They are very similar, but they are not the same. Like bats and birds who have both evolved the ability to fly but are not the same types of animals, Slerospongiae have evolved and became very similar to sponges, but they are not sponges.
Do sponges have tissues?
No, sponges do not have true tissues like other animals. They are classified as Porifera and are considered the simplest animals, lacking specialized tissues and organs. Sponges have a porous body structure with specialized cells but no distinct tissue layers.
How do sponges remove nitrogenous waste?
Sponges remove nitrogenous waste through a process called diffusion. The waste molecules passively move out of the sponge cells and into the surrounding water, where they are eventually carried away. This allows sponges to efficiently get rid of metabolic waste products from their body.

What are pore cells and collar cells?
collar cell- choancyte that is most likely in sponges
What type of animals has collar cells and osculum and spicules?
Sponges have collar cells, osculum, and spicules.
What kind of animals have collar cells an osculum an spicules?
Sponges have collar cells, osculum, and spicules.
Do jellyfish use collar cells for filter feeding?
Jellyfish do not have collar cells. Sponges have collar cells, and yes, they are used for filter feeding.
What type of animal has cells an osculum and spicules?
Sponges have collar cells, osculum, and spicules.
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 type of animal has a collar cells an osculum and spicules?
An animal with collar cells, an osculum, and spicules is likely a sponge. Sponges are simple aquatic animals that filter feed using collar cells and have a central opening called an osculum through which water exits their bodies. Spicules are tiny, hard structures that provide support and structure to the sponge's body.
What is another name for collar cells?
labarrion rusell labarrion rusell labarrion rusell labarrion rusell
Why are sponges classified as an animal?
Sponges are classified as animals because they are multicellular, heterotrophic organisms that lack cell walls. They also have specialized cells and tissues, even though they lack complex organ systems.
What organisms are found in porifera?
Porifera are sea sponges. They have no symmetry (asymmetrical) and they are one of the most basic forms of life. They have a 2 cell layer wall made of collar cells, spicules, amoeba like cells, and a layer of epidermal like cells. The spicules and the amoeba like cells are in between the layer of collar cells and epidermal cells. Sponges also have pores throughout their structure. Porifera include freshwater sponges as well of marine varieties. Freshwater sponges are common although not obvious. Frequently they are green in color due to included algae.
What is the function of the collar cell?
Collar cells are found in sponges. Their function is to beat the flagella back and forth in order to make water go through the sponge. Apart from the sponge picking food particles from the water, the collar cells also do the same.
