Porifera and Cnidaria Comparison Lesson - Biology - StuDocu.
Comparisons to Other Phyla There are a few similarities between phylum Porifera and phylum Cnidaria. Both corals (Cnidaria) and sponges create chemicals so they do not become infected and other organisms cannot grow on them. Cnidarians and sponges have symbiotic relationships with organisms that are not animals.
Compare and contrast the structure of a sponge and a jellyfish. A choanocyte has a flagella which helps pump the water in and out of the sponge to remove wastes or get nutrients Describe how the structure of the choanocyte relates to its function.
Cnidaria Introduction: Phylum Cnidaria are a marine species whose name means stinging nettle. Characteristics: Cnidarians are made of a jelly like substance, typically radically symmetrical with tentacles surrounding their mouths. Nervous System: Cnidarians have a nerve net system. Movement: At fully grown, they are sessile.
Porifera-1. They are mostly marine, non - motile, found attached to rocks. 2. They show cellular level of organization. Coelenterate - 1. Exclusively marine animals that either live in colonies or have a solitary life span. 2. They show tissue level of organization. thums up plz!
Cnidarians include jellyfish and corals. Cnidarians are less complex than annelids or mollusks because the latter have gills with many layers of tissue.
Quiz on porifera, cnidara, platyhelminthes, and nematoda. Which phylum was the first to have a one way digestive system?
In comparison, some polyp types just live 4—8 times. Duplication and Children Different cnidarians duplicate in different methods. Cnidarians can duplicate asexually by flourishing another organism increases off the primary organism, such as in anemonesor sexually, in which spawning takes place.
