Question

what is the exoskeleton, what does it do, and how is it significant to the insect? details plz

Answer 1

I think its the skin ????

Answer 2

An exoskeleton is an external anatomical feature that supports and protects an animal's body. All arthropods (such as insects, spiders and crustaceans) and many other invertebrate animals (such as shelled mollusks) have exoskeletons. Lobsters, for example, have tough outer shell systems which provide rigidity and shape to their bodies, in addition to an endoskeleton. The endoskeleton of arthropods is continuous with and an extension of the exoskeleton and is shed at the same time as the exoskeleton.

An insect's exoskeleton (integument) serves not only as a protective covering (armour) over the body but also as a surface for muscle attachment, a water-tight barrier against desiccation and a sensory interface with the environment. It is a multi-layered structure with four functional regions: epicuticle, procuticle, epidermis and basement membrane. Note that, while the arthropod exoskeleton is chitin-based, it is not composed entirely of chitin. In fact, the membranous portions of the exoskeleton and endoskeleton are closer to pure chitin than the hardened external sclerites.

Answer 4

an exoskeleton means that the skeleton is outside of the body of the animal/whatever the thing is. Its significant to insects to help protect them from anything. its like a hard to shell to break through.

Answer 6

An outside skeleton.... like a crab or lobster. Most insects also have one - but no internal skeletal system. Without an exoskeleton, they would be a blob of flesh...

Answer 7

The exoskeleton is the outer protection layer of animals like the shells. They protect their body from getting harmed.

Answer 8

in layman's terms, its the "shell' of the insect. insects dont have a bone structure, so the exoskeleton give the insect protection, shape, and a structure for tendons and muscle to attach to.

Answer 9

an exoskeleton is the hard shell that an insect (eg beetle) has. it protects the insect from predators as its hard to eat.

Answer 10

An exosceleton is an outside skeleton. It protects the animal from danger. It plays a very important role in its life because, with out it the animal wouldnt be able to move or survive.

Answer 11

The exoskelton is the outside skin of insects such as snakes who shed their skin.
