Difference Between Metagenesis and Metamorphosis

Answer. Metagenesis is the alteration of generations between sexual and asexual phases. Metamorphosis produces distinct stages during the life cycle; egg, larva, pupa, and adult. The main difference between metagenesis and metamorphosis is the distinct stages in each type of growth process.

What is the difference between Metagenesis and alternation of generation?

Alternation of generations, also called metagenesis or heterogenesis, in biology, the alternation of a sexual phase and an asexual phase in the life cycle of an organism. The two phases, or generations, are often morphologically, and sometimes chromosomally, distinct.

What is meant by Metagenesis?

: alternation of generations in animals especially : regular alternation of a sexual and an asexual generation.

What is Metagenesis with example?

The definition of metagenesis is the reproduction cycle of an organism that alternates between sexual and asexual generations. An example of metagenesis is the reproduction cycle of a cnidarian. ... (biology) The production of sexual and asexual organisms in alternate generations.

Which best describes the alternation of generations?

A gametophyte is a haploid phase best describes the alternation of generations.

Do fungi do alternation of generations?

Haploid cells undergo mitosis to produce a gametophyte. The gametophyte produces haploid gametes which fuse to form a diploid zygotic sporophyte. Alternation of generations is a reproductive cycle of certain vascular plants, fungi, and protists.

What do you mean by Metagenesis Class 11?

Answer: Metagenesis is the phenomenon in which one generation of certain plants and animals reproduce asexually, followed by the sexually reproducing generation. ... Coelenterates exhibits metagenesis (e.g., Obelia) where polyp form alternates with medusa in its life cycle.

What is Metagenesis explain how Cnidaria shows Metagenesis with example?

Metagenesis is referred to the phenomenon of alternation of generation shown by cnidarians which exhibit both forms- polyps and medusae . Polyps produce medusae asexually and medusae form the polyps sexually (e.g., Obelia).

What is Metagenesis in cnidaria?

Some cnidarians exist in polyp and medusa forms. Such cnidarians show metagenesis. It is the phenomenon of alternation of generations in which polyps produce medusae asexually and medusae produce polyps sexually. Metagenesis is observed in Obelia.

What is a polyp and a medusa?

Polyp is a sessile life cycle stage of the Cnidaria phylum. Medusa is a mobile life cycle stage of the Cnidaria phylum, contracting with it muscular bell. Polyp have a tubular shape and are fixed at their base, with the mouth present at the other end of the tube facing the water.

What is polymorphism in obelia?

The phenomenon of occurrence of an individual in two or more distinct morphological and functional forms. It occurs in the same species of an individual. Each individual member of Coelenterates is known as Zooid and they often units to form a colony which acts as a single unit (individual). ...

What is Metagenesis in zoology?

metagenesis The occurrence, during the life cycle of an organism, of two types of individual, both diploid, both of which reproduce, one sexually and the other asexually. The term is sometimes used loosely (but incorrectly) as a synonym for the alternation of generations. A Dictionary of Zoology MICHAEL ALLABY.
