list of the phylum of kingdom animalia |
Porferia Cnidaria Platyhelminthes Mollusca Annelida Arthropoda Nematoda Echinodermata Chordata |
|
characteristics of Porferia |
simplest form of life -no mouth, digestive tract, muscles, or nervous system -live in water -filter feeders (water moves through the organism into pores to get the food) -sessile (dont move) -asymmetrical body plan (no symmetry) -pores all over the body |
|
examples of Porferia |
sponges |
|
characteristics of Cnidaria |
-live in water -2 layered animals -cells make tissues -gastrovascular cavity (functions in digestion, circulation, and gas exchange) -MOST have tentacles -catch food with stinging cells
|
|
examples of Cnidaria |
aneome jellyfish corals |
|
characteristics of Platyhelminthes |
-flat, ribbon like bodies -live in water or as parasites -few internal organs or tissues (flat body allows for easy gas exchange) -have a mouth and digestive cavity |
|
examples of Platyhelminthes |
flatworms (tapeworms) |
|
characteristics of Mollusca |
soft bodies with an outer shell -hard shell made of calcium carbonate -circulatory and complex nervous systems -aquatic or terrestrial -have 3 parts: food, mantle, viseral body |
|
examples of mollusca |
squids and octopus snails clams, oysters, scallops (2 shells) |
|
characteristics of Annelida |
segmented worms (more specialized)
-freshwater or terrestrial -seperate male and female sexes -have digestive cavity, circulatory system, gas exchange through skin, and nervous system |
|
examples of Annelida |
earthworms leeches |
|
characteristics of Anthropodia |
BIGGEST PHYLUM body is divided into different sections -evolved from the annelidas -have an exoskeleton made of CHITIN -jointed legs -nervous, digestive, and OPEN circulatory system |
|
3 sub-phylum of anthropoda? |
1. Arachnids
-spiders, ticks, scorpions 2. Merostomata -horseshoe crabs 3. Crustaceans -shrimp, lobsters |
|
examples of anthropoda |
scorpions, spiders, ticks |
|
characteristics of Nematoda |
round, tubular bodies -microscopic (pond water) -have a mouth and anus (complex digestive systems) -NO respiratory or circulatory systems -aquatic or parasitic |
|
examples of Nematoda |
hookworm ,trichinella |
|
characteristics of Echinodermata |
hard, spiny skin -live in SALT water -radial symmetry for adults, bilateral for larva -can regenerate lost parts -endoskeleton -tubed feet |
|
examples of Echinodermata |
sand dollars, sea cucumber, sea urchins, seastar |
|
classes of Chordata (hint. 5) |
Fish Amphibians Birds Reptiles Mammals |
|
characteristics of Chordata |
have a backbone 5% of all species |
|
Characteristics of all Animalia |
1. multicellular (most have specialized forms of tissues) 2. eukaryotic- no cell wall 3. heterotrophs (movement relates to obtaining food) 4. develop from a zygote (single layer of cells around a fluid filled space forming a hollow ball of cells galled a gastrula) |
|
3 layers of gastrilation |
Ectoderm: skin and nervous tissues (OUTSIDE) Mesoderm: forms muscles, reproductive organs, and circulatory vessels- only in complex animals (MIDDLE) Endoderm: develops into the lining of digestive tract (INSIDE) |
|
what is bilateral symmetry |
can be divided down its length to have the same on left and right (like a mirror) -one cut makes two equal parts |
|
what is radial symmetry |
divide by any axis on the animal and you will get 2 equal halfs (through central axis) |
|
what is diploblastic and what phylum are this? |
2 germ layers (no mesoderm) to become tissues -Cnidaria |
|
what is triblastic and what phylum have this? |
3 germ layers that become tissues -Platyhelminthes Mollusca Annelida Arthropoda Nematoda Echinodermata Chordata |
|
what is protostome development and what phylums have this? |
develop mouth first -platyhelminthes -mollusca -annelida -anthropoda -nematoda |
|
what is deuterostome development and what phylums have this? |
develop anus first -Echinodermata -Chordata |
|
what is an acoelomate |
no cavity (space) to have organs (why there are very few organs- less complex) ex. Platyhelminthes |
|
what is a coelomate |
have a cavity to house numerous organs (more complex structure) Mollusca Annelida Arthropoda Nematoda Echinodermata Chordata |
|
CHORDATA: fish |
aquatic cold blooded external fertilization gas exchange through gills |
|
CHORDATA: amphibians |
aquatic cold blooded 2 parts to their life cycle external fertilization moist skin for gas exhange ex. frogs, toads, salamanders |
|
CHORDATA: reptiles |
cold blooded terrestrial eggs have a leathery shell (to protect from dehydration laid on land) internal fertilization hard scaly skin ex. snakes, crocs, lizards, TURTLES |
|
CHORDATA: Birds |
warm blooded feathers internal fertilization with a hard shell |
|
CHORDATA: mammals |
hair/fur give birth to live young (feed young milk) warm blooded |
|
3 orders of mammals |
Placentals Marsupials Monotremes |
|
characteristics of placentals |
give birth to well-developed young due to longer time in the womb (gestation) -placenta is the link between embryo and mom (for waste, gas, and nutrient exchange) |
|
characteristics of marsupials |
birth to very immature young that then go into the moms pouch to attatch to the teat ex. kangaroos, koala, wombat, opposums |
|
characteristics of monotremes |
egg laying mammals ex. duck-billed platypus, spiny anteaters (echidna) |
|
define tetrapods |
4 legs (everything in Chordata except fish) |
