Porifera sponge diagram. They are sessile and sedentary and grow like plants.



Porifera sponge diagram. The cumulative effect of the flagella from all choanocytes aids the movement of water through the sponge: drawing water into the sponge through the numerous ostia, into the spaces lined by choanocytes, and eventually out through the osculum (or osculi). Aug 3, 2023 · Porifera are all aquatic, mostly marine except one family Spongillidae which lives in freshwater. The vast majority of sponges are organized in a more complex way, the leucon condition, with folds upon folds, resulting in a series of flagellated chambers connected by canals. This article includes phylum Porifera class 11 definition, meaning, characteristics, classification, examples, notes and diagrams. Overview Sponges make up the simplest animal group on the planet: phylum Porifera (from the Latin porus ‘pore’ and ferre ‘to bear’). The group consists of approximately 15,000 extant species in three distinct groups (Hooper and van Soest 2002): the glass sponges (Class Hexactinellida) the calcareous sponges (Class Calcarea) the demosponges (Class Demospongiae . The diagram above shows the basic structure of a sponge, with key features like the spongocoel (central cavity), ostia (pores), osculum (exit opening), and specialized cells. Spongin is the flexible material that makes up the body wall of the sponge, while spicules Jul 2, 2025 · Phylum Porifera includes simple, sponge-like animals that live mostly in water and have porous bodies for filtering food and oxygen. Sponges belong to the kingdom animalia and the phylum porifera, though at one time they were thought to be plants. Let’s dive deep into the world of sponges! 🌊 Start studying Porifera--sponges. A simple folding of the wall yields a sponge body with sycon organization.

In this worksheet, read about sponges, and color a sponge to illustrate your knowledge of sponge anatomy. Mineral Skeleton (Spicules) selections bring up microphotographs and drawings of skeletal spicules and refer to their characteristics. The body shape is vase or cylinder-like, asymmetrical, or radially symmetrical. Having no digestive tract, localized sensory region, or true tissues, they are little more than a cluster of cells supported by a structure of spongin and spicules. Introduction Sponges (phylum Porifera) are an exclusively aquatic and, with a few exceptions (Vacelet and Boury-Esnault 1995), a filter-feeding group of animals. They are sessile and sedentary and grow like plants. trftws qq uns7 mac kvfw t5a va srr1 wc e908
