Flashcards

Metamorphosis

The process of transformation from an immature to a mature form in certain animals. It involves significant changes in body structure and function.

Typical outcome of metamorphosis

A rapid and significant change in an organism's body structure, often involving molting and complete reorganization of tissues.

Pupa stage

The stage in complete metamorphosis where an insect is in a resting, inactive state, enclosed within a hardened cocoon or chrysalis.

Humans do not undergo metamorphosis

Humans, unlike insects, develop directly from an embryo to an adult without undergoing major structural changes. Humans do not experience major changes of the body, but rather a gradual development from childhood to adulthood.

Hemimetabolous metamorphosis

A type of metamorphosis in which the young resemble smaller versions of the adults. Development involves gradual changes in size, shape, and structure.

Holometabolous metamorphosis

A type of metamorphosis characterized by four distinct stages: egg, larva, pupa, and adult.

Short lifespan of adults

A disadvantage of complete metamorphosis, where the adults have a shorter lifespan compared to the larval stage, due to the energy expenditure of transforming.

Incomplete metamorphosis

Grasshoppers are insects that undergo a form of metamorphosis where the young stages are smaller versions of the adults. Their development is gradual, without a distinct pupal stage like the Holometabolous insect.

Hypermetamorphosis

A type of metamorphosis characterized by an extra stage in the larval phase, where the larva goes through a period of regression and then re-growth. It's a complex change within a change.

Study Notes

Metamorphosis Examples and Characteristics

  • An example of metamorphosis is the transformation from a caterpillar to a butterfly.
  • The typical outcome of metamorphosis is the formation of a fully developed adult with distinct physical characteristics.

Stages of Metamorphosis

  • In complete metamorphosis, the life stage that comes after the larva stage is the pupa stage.
  • In incomplete metamorphosis, the life stage that comes after the larva stage is the adult stage.

Exceptions to Metamorphosis

  • An exemption to the complete cycle of metamorphosis is the development of some species of fish, which undergo a gradual transformation from juvenile to adult.

Types of Metamorphosis

  • Hemimetabolism is characterized by the stages: egg, nymph, and adult.
  • Holometabolism is also known as complete metamorphosis, characterized by distinct larval and pupal stages.

Complete Metamorphosis Disadvantages

  • A disadvantage of complete metamorphosis is the vulnerability of the pupa stage to predators and environmental factors.

Incomplete Metamorphosis Examples

  • Grasshoppers undergo incomplete metamorphosis, with distinct juvenile stages (nymphs) that resemble small adults.

Hypermetamorphosis Characteristics

  • Hypermetamorphosis is distinguished from other types of metamorphosis by the presence of multiple, distinct larval stages, each adapted to a specific environment.
