What are the characteristics of Coelenterata?
Characteristics. All coelenterates are aquatic, mostly marine, animals. The body form is radially symmetrical, diploblastic and does not have a coelom. The body has a single opening, the hypostome, surrounded by sensory tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey.
What type of development is Coelenterata?
Answer. Indirect development takes place in coelenterata.
Which structure is characteristic of all coelenterates?
Phylum coelenterata characteristics is they have a single opening into the body which acts as both the mouth and anus which functions in taking food and expelling wastes.
Which branch of biology describe about coelenterates?
Cnidology
So, the correct answer is ‘Cnidology’
Which type of development is seen in Cnidaria?
There are two main types of cnidarian life cycle. In anthozoans, the polyp is the gamete-producing form and the cycle is embryo>larva>polyp. Medusozoans generally have an embryo>larva>polyp>medusa life cycle, in which the medusa is typically the sexual form (Fig. 2).
What are the important types of Coelenterata?
The Phylum Coelenterata consists of marine organisms that have a body that is radially symmetrical and a mouth that has sensory tentacles that help in capturing prey easily. Other animals belonging to the Phylum Coelenterata are hydra, comb jellies, true jellies, sea pens, coral animals, sea anemones and more.
What are three functions of the endoderm in coelenterates?
Three functions of the endoderm in coelenterates are breaking down food nutrients, absorbing oxygen, and removing wastes from the coelenterates.
What is development in Cnidaria?
Cnidarians nominally develop from two germ layers, the ectoderm and endoderm, whereas the presence of a third germ layer, the mesoderm, traditionally characterizes higher animals. This apparently fundamental developmental difference led to these groups being referred to as diploblasts and triploblasts, respectively.
How do coelenterates reproduce?
They reproduce asexually by budding. Some groups are observed in which sexual reproduction takes place. They live in water and have well-differentiated body design.
