QuestionAnswer
largest class Insecta
Eats every kind of plant including most agricultural crops Insecta
2 ways insecta benefits 1. eat weeds which compete with the crops 2.primary crop pollinators
Coelom and segmented body insecta
they are characterized by there ____ mouth
what are the 2 types of mouth 1. Mandibulates 2. Chelicerates
jaws – crustaceans, insects, centipedes and millipedes Mandibulates
fangs or pincers – spiders, mites and scorpions Chelicerates
jointed legs and other appendages that allow for more flexibility Jointed appendages
all of them are this and the adults are the more advances species that have segments fused to form a head thorax and abdomen segmentational
most are distinct which are fused with the thorax (Cephalothorax) head
the head is fused with the thorax Cephalothorax
skeleton on the outside exoskeleton
the exoskeleton shed occationally Ecdysis
made of 1000 individual units that cant focus really well but the can detect movement very well compound eye
how they breath through Tracheae spiracles
fine tubes that air goes through spiracles and open and closed by valves Tracheae
what type of circulation does insecta have open circulatory system
compose of the excretory units they are slander finger like structures that extend form the gut waste pass through it and exits at the anus Malpighian tubules
used to fly wings
what class is subphylum Chilicerata in class Arachnids
what is in the class arachnids Spiders, ticks, mites, scorpions, daddy long legs
what are arachnids (carnivore or herbivore) carnivore (except for mites)
how do Arachnids catch there pray Inject enzymes into there pray which liquefies the tissue then they suck in up
4 pairs of Legs, fused body region, mouth chelicerae Arachnids
Large grasping pincers for handling and tiring apart there food and for reproducing (dancing) scorpions
on the tail of a scorpian which is used to stun there pray Venomous stinger
Poison glands that secret toxins so that when they bit it paralyzes there pray spiders
spiders Techniques to catching prey (3) 1.run them down 2. hide in burrows that they built and then pop out when something pop by 3. sticky web
Head, thorax and abdomen all fused together mites
what is in the Subphylum Crustacea Crabs, lobsters, crayfish, shrimp, barnacles, water fleas and pill bug
- Jaws - Exoskeleton: made of calcium carbonate - Two pairs antennae (insects have 1) - Legs attached to abdomen as well as thorax - Gills: breath with Subphylum Crustacea
what are the 3 classes of Subphylum Uniramia millipedes, centipedes, and Insecta
each stage is very different Complete metamorphosis
the stages don’t differ as much the nymph which is the juvenal looks like a small version of the adult incomplete metamorphosis
what are the 2 life cycles complete metamorphosis incomplete metamorphosis
2 antenna and they contain since organs so they can both touch and smell head
what are the grasshoppers 4 lips labrum labium mandibles maxillas
stiff upper lip labrum
lower lip labium
jaws mandibles
grass spurs maxillas
2 pars of wings the leathery fore wings protect the more delicate flying wings grasshopper
repertory system (breathing) Spiracles
3 fused segments thorax
front 2 pair used for walking and the rear 2 for jumping grass hopper legs
where is the reproductive system of a grasshopper located abdomen
what is the process of the reproductive system of a grasshopper The female collects sperm from the seriating male and then later in the summer she digs a hole releases her eggs into the hole which gets fertilized as she releases them
what is the circulatory system of a grasshopper open which is composed of long blood vessels along the back an a series of muscular hearts
what is in the Echinoderms and Invertebrate Chordates starfish
- Radial symmetry - No head or brain starfish
consist of a symmetrical ring of nerves with branches extending into the arms nervous system of a starfish
Endoskeleton is composed of individual plates called ossicles
provide muscle attachment and shell like protection ossicles
5 arms that extend radially from a central point 5 part radial symmetry
there enter connected canals and tube feet filled with water water vascular system
the body cavity acts like a simple circulatory system and the particles move freely throughout Coelomic circulation of a starfish
preformed by skin gills which are small finger like projections that grow between the spins Respiration and waste removal
