Cnidaria More on Morphology Cnidarians are said to be the simplest organisms at the tissue grade of organization their cells are organized into true tissues Cnidarians are essentially bags made of two cell layers The outer ectoderm or epidermis contains the cnidocysts the stinging cells that are characteristic of the phylum
Templates are pre-designed documents or files that can be utilized for different purposes. They can save effort and time by offering a ready-made format and layout for producing various type of material. Templates can be utilized for personal or expert jobs, such as resumes, invitations, flyers, newsletters, reports, presentations, and more.

The phylum Cnidaria pronounced nih DARE ee uh includes soft bodied stinging animals such as corals sea anemones and jellyfish Fig 3 23 A The phylum s name is derived from the Greek root word cnid meaning nettle a stinging plant Cnidarians are found in many aquatic environments

The body wall of a cnidarian consists of three layers an outer layer known as the epidermis a middle layer called the mesoglea and an inner layer referred to as the gastrodermis The epidermis contains a collection of different types of cells

Cnidarian Body Plans Cnidarians may exist in the polyp left or medusa right form The body of a cnidarian consists of two cell layers ectoderm and endoderm The cellssurround a digestive cavity called the coelenteron see Figure below Cnidarians have a simple digestive system
https://www.ck12.org/biology/Cnidarian-Structure
The anatomy of cnidarians is based on two distinct body types called the polyp polypoid which is normally sessile and the medusa medusoid which is normally free floating Often the cnidarian life cycle involves an alternation of generations in which the organisms can switch between the polyp and medusa forms
Life cycle of most jellyfish Many cnidarians alternate between the two different body forms during their lives One is the free swimming form called a medusa and the other is a stationary form called a polyp Both body forms follow the same basic cnidarian body plan The polyp is sessile living on a substrate with the tentacles extending up and Cnidarian Table of Contents Cnidarian Polyp Medusa Tentacles Cnidarians have two cell layers ectoderm and endoderm gastrodermis with the mesoglea between them Medusae have a more highly developed nerve net than do polyps Respiration and excretion are carried out by individual cells
Cnidarians mostly have two basic body forms swimming medusae and sessile polyps both of which are radially symmetrical with mouths surrounded by tentacles that bear cnidocytes Both forms have a single orifice and body cavity that are used for digestion and respiration
