Question 11

Is a biological process by which an animal (ecdysozoans) physically develops including birth or hatching, involving a conspicuous and relatively abrupt change in the animal’s body structure through cell growth and differentiation
.

Answer 11

Metamorphosis

Question 12

What are the types of Development?

Answer 12

1. Ametabolous
2. Hemimetabolous
3. Paurometabolous
4. Holometabolous

Question 13

No metamorphosis. These insects are primitively wingless where the only difference between adult and nymph is size.

Answer 13

Ametabolous

Question 14

Incomplete metamorphosis - The immature stage inhabits in water and are called naiad. Wings appear as buds (wing pad) on the early instars. When the last molt is completed the wings expand to the full adult size.

Answer 14

Hemimetabolous

Question 15

Incomplete metamorphosis
- The immature stage inhabits in terrestrially and are called nymphs. Insect young are usually similar to the adult. Wings appear as buds on the nymphs or early instars. When the last molt is completed the wings expand to the full adult size.

Answer 15

Paurometabolous

Question 16

Complete metamorphosis
- These insects have a different form in their immature and adult stages, have different behaviors and live in different habitats.

Answer 16

Holometabolous
