Insect Development and Life Cycle

The video tutorial explores the concept of metamorphosis, focusing on the life cycles of dragonflies and grasshoppers. It explains the stages of development from egg to adult, highlighting the differences between complete and incomplete metamorphosis. The tutorial also covers embryonic development, detailing the formation of cells and organs in larvae. Key differences in morphology and structure during various molts are discussed, providing a comprehensive understanding of insect development.

What is the term used to describe the development process where the larva resembles the adult form?

What happens during the early stages of insect development within the egg?
