Question | Answer |
---|---|
What are the 2 key characteristics that all arthropods share in common? | +Segmented bodies +Jointed appendages |
What is the special skeleton of arthropods? | +Possess a hard exoskeleton (bo xuong ngoai) made by chitin and protein that is secreted by and remains fused to the epidermis |
What is the function of exoskeleton? | +A continuous structure with overlapping folds. ( nep gap) allowing body to bend and the appendages( phan phu) to move. +Provides support for the body , provides an anchor for muscle attachment +protect the animals from predators and impedes waterloss |
Do arthropod has coelom? | Yes it is |
Characteristics of arthropods | +The main body cavity is a Hemocoel comprising part of the Open Circulatory System +The nervous system is like annelids, consisting of the dorsal brain and a single ventral nerve cord. |
The specialized respiratory organs of athropods | Varying from Gills in crustaceans, to Book Lungs in arachnid, to Tracheae and Spiracles in insect |
The specialized excretory organs of arthropods for eliminating metabolic waste? | The Malpighian tubules found in insect. |
Major innovation of arthropods? | +Bilaterally symmetry, three primary germ layers, a true coelom and segmentation +2 key elements: Jointed appendages(used for walking, flying feeding, reproducing, and sensing the envi) and an exoskeleton |
Subphylum Myriapoda includes classes and animals? | +Chilopoda (Centipedes) +Diplododa (Millipedes) |
The traits and characteristics of Chilopoda (Centipedes)? | +Cylinical body divide into head and segmented trunk +One pair of legs per body segment +One pair of antennae ( rau) +Poison fangs( rang nanh) absent;teresstrial |
The characteristics of Diplopoda | +Cylinical body divide into head and segmented trunk +2 pairs of legs per body segment +One pair of antennae +poison fangs absent;terrestrial |
Subphylum Crustacea includes? | +Malacostraca( Crayfish, lobster, crabs...) |
What are the characteristics of Malacostraca class ? | +2 pair of antennae +Biramous appendages +one pair of madibles (ham duoi) +Two pair of maxillae (xuong ham) +marine, freshwater, or terrestrial |
Subphylum Hexapoda includes? | +Insecta (Insects) |
What are the characteristics of insecta class ? | +body divided into head, thorax (nguc), and abdomen (bung duoi) +Three pair of legs on thorax +one pair of antennae +Primarily teresstrial |
special about anthropods? | The first animal to inhabit land, predating other familiar ancient The first animal to fly |
Characteristics of centipedes? | +Carnivorous predator that feed on worms and insect +body is divided into head and a trunk. +one pair of legs per body segment + A single pair of antennae on the head, and a pair of appendages modified into poison fangs. |
Characteristic of Millipedes ? | +Slow, docile herbivores feed on vegetation. +prefer dark, moist areas +Their clindrical body is divided into a head and a multi-segmented trunk + Two per of legs per body segments +single pair of antennae without poison fangs . |
Characteristics of Crayfish? | + Divided into two main regions ,The cephalothorax and the abdomen +appendages are present on both regions, +Rostrum,a pair of stalked, compound eyes, and 2 pairs of antennae +The longer pair is antennae, shorter is antennules |
What organ does crayfish use for defense purpose and capturing killing prey? | Cheliped. |
What are the characteristics of Insects? | +3 pairs of uniramous (Unbranched) walking appendages +1 pair of antennae +3 distinct body regions: Head, thorax, and abdomen |
What are the evolution that allowed insects to thrive despite the challanges of a terrestrial environment | +Stronger support system and stronger walking appendages to overcome the forces of gravity +waxy(sap) cuticles( vo) built to withstand the osmotic (tham thau) of dry air, yet adapted for gas exchange |
Continue of evolutin in insects | +Ability to fertilize eggs internally to prevent desiccation( su kho rao) of exposed gametes +Specialized respiratory, excretory, and digestive structures modified to conserve water +appendages modified into wings to take advantage of aerial habitats |
