What is the importance of polymorphism in Coelenterates?

Importance of polymorphism: It is essential for division of labor among the individual zooids. Different functions are assigned to different forms. For examples; polyps are concerned with feeding, protection and asexual reproduction whereas medusa are concerned with sexual reproduction.

Which cnidarian is not polymorphic?

Physalia is not polymorphic.

What is polymorphism in Coelenterata with example?

Polymorphism: Coelenterates having more than three types of individuals are called polymorphic, e.g. Hydractinia which has five types of zooids, each performing a specialized function. Gastrozooids are for feeding, spiral dactylozooids for protection, long tentaculozooids have sensory function.

Which of the following Coelenterates does not exhibit polymorphism?

Hydra
Hydra is also a coelenterate but fails to exhibit polymorphism, this is not the correct answer.

What animals show polymorphism?

The term polymorphism also refers to the occurrence of structurally and functionally more than two different types of individuals, called zooids, within the same organism. It is a characteristic feature of cnidarians.

What is polymorphism explain with reference to obelia?

Obelia:- Polymorphism is a common feature of coelenterates. It is the phenomenon of presence of several types of zooids in a single colony. These zooids are formed by the modifications of polyps and medusae.

What is alternation of generation in coelenterates?

Alternation of generation may be defined as a phenomenon whereby, in the life history of an organism a diploid asexual phase and a haploid sexual phase regularly alternates with each other.

What is the importance of polymorphism?

Polymorphism is considered one of the important features of Object-Oriented Programming. Polymorphism allows us to perform a single action in different ways. In other words, polymorphism allows you to define one interface and have multiple implementations.

What is the significance of polymorphism?

Polymorphism is common in nature; it is related to biodiversity, genetic variation, and adaptation. Polymorphism usually functions to retain variety of form in a population living in a varied environment.

What is polymorphism How is it beneficial to cnidarians?

POLYMORPHISM IN CNIDARIA This occurrence of polymorphism guarantees well-organized division of labor between several individuals. In coelenterates different individuals get united in the form of a colony and hence polymorphism is a very important feature of this phylum.

What causes polymorphism?

According to the theory of evolution, polymorphism results from evolutionary processes, as does any aspect of a species. It is heritable and is modified by natural selection.

What is polymorphism in phylum Coelenterata?

Polymorphism is an important feature of phylum coelenteratea. Each individual member of Coelenterates is known as Zooid and they often units to form a colony which acts as a single unit (individual). Polymorphic form in coelenterata: two types of zooids Coelenterates which may be single or colonial, they exists in two forms- polyps and medusa

Which coelenterates are monomorphic and which are polymorphic?

A few coelenterates, such as Hydra and sea anemone are monomorphic in which only polyp stage is found but other coelenterates exhibit polymorphism.

What is polymorphism in biology?

The occurrence of more than one type of structurally and functionally different individuals within a population is called polymorphism. The class Hydrozoa of phylum Coelenterata includes a large number of colonial species that contain more than one form of individuals which are called zooids

What are coelenterates?

Each individual member of Coelenterates is known as Zooid and they often units to form a colony which acts as a single unit (individual). Coelenterates which may be single or colonial, they exists in two forms- polyps and medusa
