Choanocytes Study guides, Class notes & Summaries

WSU Biology 106 Exam 3 Questions Marking Scheme Spongocoel - ANSWER- the large central cavity of sponges. water enters the spongocoel through tiny pores called ostia and it exits through the large opening called the osculum. spongocoel is lined with choanocytes which help to create a current in the water. Spicule - ANSWER- structural elements found in most sponges. They provide structural support and deter predators. Large ones are called megascleres while microscopic ones are calle...

binomial nomenclature - ANSWER-Classification system in which each species is assigned a two-part scientific name biological species concept - ANSWER-Species is a group of populations whose members have the potential to produce fertile offspring. What makes something an animal? - ANSWER-They respire, are multicellular, eukaryotic, Volume to surface area ratio of cells - ANSWER-As the radius of the cell increases, its surface increases as the square of its radius, but its volume increases ...

Phylum Porifera (sponges) asymmetrical lack true tissues have unique cells called CHOANOCYTES (flagellated cells that will draw in water and filter food particles) Genus: Grantia, Spongia, Euplectella Phylum Porifera Genus Grantia isolated spicules walls of sponges contain amoebocytes and crystallized structures called spicules incurrent canals and flagellated canals 00:00 01:22 Phylum Porifera Genus Spongia have spongin fibers that are more flexible live spe...

Phylum Porifera - No true tissues Asymmetrical symmetry Taxa: -Silicea (glass sponges) -Calcarea (rest of sponges) Osculum - Water exit in sponges Spicules - -Skeletal components of sponges made of silica, calcite or spongin -Produced by amoebocytes Choanocytes - Spong's filter-feeding cells
