What is the function of spicules in sponges they draw food and oxygen into the body they filter and digest food they provide protection from predators they produce sperm and eggs?
What is the function of spicules in sponges they draw food and oxygen into the body they filter and digest food they provide protection from predators they produce sperm and eggs?
Answer: Your answer will be 3) They provide protection from predators.
What are spicules in anatomy?
1 : a slender pointed usually hard body especially : one of the minute calcareous or siliceous bodies that support the tissue of various invertebrates (such as sponges) 2 : a spikelike short-lived prominence appearing close to the chromosphere of the solar atmosphere.
What are spicules quizlet?
spicules. small needlelike structures made from archaeocytes that are support structures of the sponge, made of calcium carbonate, silica, or spongin.
Are Cnidocytes significant to fundamental processes?
Are the cnidocytes significant to fundamental processes for cnidarians? Cnidocytes are fundamental for food capture by cnidarians. They trap and slow down prey so that the cnidarian can get food for maintenance, growth, and reproduction.
What is the function of Cnidocytes?
Cnidocytes (‘stinging cells’) are specialized cells that define the phylum Cnidaria (sea anemones, jellyfish, corals and hydras). They contain an “explosive” organelle called cnidocyst that acts as a 600 million-years-old microscopic injection system and is important for prey capture and anti-predator defense.
Why are Hydroids referred to as colonial animals?
Why are hydroids referred to as colonial animals? List the different functions of hydroid polyps. Unlike sea anemones, which live alone or in small groups, coral polyps live in large groups as colonial animals, attached to one another by a thin membrane.
What is the function of Spongocoel?
The spongocoel is lined by a variety of cell types, each having a unique function: Porococytes–These cells line the pores of the sponge. They are the structure through which water is taken into the organism.
What is the main basis of classification of sponges?
Sponges lack true tissues, have no body symmetry, and are sessile; types are classified based on presence and composition of spicules.
What is the main basis of classification in the five kingdom system?
The main criteria of the five kingdom classification were cell structure, body organisation, mode of nutrition and reproduction, and phylogenetic relationships.
What is the basis of classification of porifera based on?
The classification of phylum Porifera is based upon the presence and composition of spicules.
