What are some distinguishing characteristics of the phylum Arthropoda?

Answer 1

Arthropods commonly have: * Segmented bodies, both internally and externally * They are bilaterally symmetrical * An arthropod's body is covered with an exoskeleton composed mainly of chitin in a protein matrix * The exoskeleton may also have some composition of lipids, other proteins, and calcium carbonate * Body segments sometimes have jointed appendages * As arthropods grow, they often lose their exoskeleton by a process of molting, known as ecdysis * Most arthropods have a pair of compound eyes * They respire through the body surface or by means of gills, tracheae, or book lungs * Most arthropods lay eggs, and the young develop through a process of metamorphosis

Answer 2

1. Jointed legs

2. Hard, outside skeleton

3. Live in water and on land

Answer 3

Phylum Arthropoda is distinguished by the following characters .

1 : Their Appendages are jointed .

2 : Their body is segmented .

3 : Their body is covered by Chitinous exoskeleton .

4 : Their body is tagmatised i.e. they possess head , thorax abdomen or cephalothorax and abdomen .

5 : They have Malpighian tubules for excretion .

6 : They have ventral nerve cord .

7 : Examples Insects , spiders .

Answer 4

- segmented legs (that´s what their name means) and body.

- distinct mouthparts made out of modified legs. (these guys are all about legs.)

- exoskeleton replaced through molting.

Not compound eyes as Spiders don´t have these.

Answer 5

Arthropods have segmented bodies, jointed appendages, an exoskeleton made of chitin, and bilateral symmetry. They also have a system of open circulatory system and a ventral nerve cord. Additionally, they exhibit a wide range of specialized adaptations for different environments and lifestyles.
