NEET BIOLOGY

Detailed explanation-1: -All arthropods posses an exoskeleton, bi-lateral symmetry, jointed appendages, segmented bodies, and specialized appendages. The major arthropod classes can be separated by comparing their number of body regions, legs, and antennae. Class Crustacea (crus-ta-ce-uh), the crustaceans. This is a very diverse class.

Detailed explanation-2: -Arthropods (/ˈɑːrrəpɒd/, from Ancient Greek (arthron) ‘joint’, and (pous) ‘foot’ (gen. )) are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages.

Detailed explanation-3: -All arthropods have a hard exoskeleton made of chiton, a type of protein. This shell provides protection for the animals, and gives support for the attachment of the arthropod’s muscles. Although arthropods grow, their exoskeletons do not grow with them.

Detailed explanation-4: -All arthropods (arthro = joint, pod = foot) have jointed limbs. In most of the leg, the exoskeleton is hard, but at the joints it is softer and bendable, allowing movement in the same way that a suit of armor does.

Detailed explanation-5: -There are over 800, 000 named species in the Phylum Arthropoda, named from the Greek arthros (= jointed) and poda (= foot), including the familiar arachnids, crustaceans, and insects, together with a host of less familiar critters, like centipedes, millipedes and sea spiders. All arthropods have jointed appendages.
