What material is the exoskeleton of arthropods comprised?

Answer 1

The exoskeleton of arthropoda is made of a tough protein called chitin, a long chain polymer comparable to cellulose. It fills the same role as the protein keratin in other animals where it would be found in hair, nails, hooves, claws, beaks, etc.

Some arthropods, like crustaceans, further harden their chitin exoskeleton by biomineralization with calcium carbonate. Because it is inflexible, the organism has to periodically shed it (moult) in order to grow.

Answer 2

The exoskeletons of arthropods are made of a tough protein called chitin, usually further hardened by the organism through biomineralization, for example with calcium carbonate. Chitin is a long-chain polymer molecule comparable to cellulose, and forms the same role as the hard protein keratin in hair, nails, hooves, beaks, and claws for others in the animal kingdom.

Because it is rigid and does not expand, arthropods have to periodically shed (moult) their entire exoskeleton in order to grow, then wait for their new exoskeleton to harden. Some arthropods recover some of the material by eating their discarded exoskeleton.

Answer 3

Arthropod exoskeletons are made of a tough protein called chitin, a long-chain polymer which is similar to the polysaccharide cellulose, and often futher hardened by biomineralization, for example with calcium carbonate.

Answer 4

Exoskeleton of Arthropods is made up of chitin , Chitin is a complex carbohydrate and it contains nitrogen along with C , O and H atoms . Chitin is light weight , it is also present in Fungi .

Answer 5

Yes all arthropods have an exoskeleton which is derived from glucose.

Arthropods a segmented body and jointed attachments called appendages.

Answer 6

All arthropods have exoskeletons. Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages.

Answer 7

Chitin.

Answer 8

Chitin.
