5 Questions
What is metamorphosis?
Metamorphosis is a biological process by which an animal physically develops, including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.
Which organisms undergo metamorphosis?
Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis.
What is the etymology of the word 'metamorphosis'?
The word metamorphosis derives from Ancient Greek μεταμόρφωσις, 'transformation, transforming', from μετα- (meta-), 'after' and μορφή (morphe), 'form'.
What are the three categories into which animals can be divided based on metamorphosis?
Animals can be divided into species that undergo complete metamorphosis (holometaboly), incomplete metamorphosis (hemimetaboly), or no metamorphosis (ametaboly).
How are growth and metamorphosis controlled in insects?
In insects, growth and metamorphosis are controlled by hormones synthesized.
Study Notes
Metamorphosis
- Metamorphosis is a biological process that involves a significant and rapid change in an animal's body structure through cell growth and differentiation.
- This process occurs from birth, transformation, or hatching, and is often accompanied by a change in nutrition source or behavior.
Types of Metamorphosis
- There are three types of metamorphosis: complete (holometaboly), incomplete (hemimetaboly), and no metamorphosis (ametaboly).
Characteristics of Metamorphosis
- Organisms with a larval stage undergo metamorphosis.
- During metamorphosis, the organism loses its larval characteristics.
Etymology of Metamorphosis
- The word "metamorphosis" comes from Ancient Greek μεταμόρφωσις, meaning "transformation, transforming".
- The word consists of two parts: μετα- (meta-), meaning "after", and μορφή (morphe), meaning "form".
Hormonal Control of Metamorphosis
- In insects, growth and metamorphosis are controlled by hormones synthesized in the body.
