Name the eight classification levels for an animal: A human or a skunk.
Human: Skunk: Domain: Eukaryotes. Eukaryotes Kingdom: Animalia. Animalia Phylum: Chordata. Chordata Class: Mammalia. Mammalia Order: Primates. Carnivora Family: Hominidae. Mephitidae Genus: Homo. Mephitis Species: sapiens. mephitis
Name the eight classification levels for a plant: Long-leaf pine.
Domain: Eukaryote Kingdom: Plantae Phylum: Tracheophyta Class: Pinopsida Order: Pinales Family: Pinaceae Genus: Pinus Species: palustris
Name the seven animal phyla?
Porifera Cnidaria Platyhelmintha Annelida Mollusca Arthropoda Chordata
Describe the characteristics and give examples of the animal phylum Porifera.
Example: sponges Sessile (don't move) Larval stages can swim Critical for ecosystems (filter feeders) No symmetry Some have an internal skeleton No organs or organ systems
Describe the characteristics and give an example of the animal phylum Cnidaria.
Example: jellyfish, coral, hydra
Stinging cells (cnidocils) that can release toxins
Radial symmetry
Two tissue layers
Describe the characteristics and give examples of the animal phylum Platyhelmintha.
Example: Flatworms (tapeworm, flukes, planaria)
First organisms to have bilateral symmetry
Planaria were first organisms to have a brain
Describe the characteristics and give an example of the animal phylum Annelida.
Example: segmented worms (earthworms, sand worms, leaches)
Segmented bodies allow worm to move through the soil
Breathe through skin
Describe the characteristics and give an example of the animal phylum Mollusca.
Example: Mollusks (clams, snails, Cephalopoda, squid, octopus, cuddle fish)
Non segmented bodies
Muscular foot
Most have a shell or two (can be located inside the body)
Describe the characteristics and give an example of the animal phylum Arthropods.
Example: lobsters, shrimp, cray fish, spiders, ticks, insects, horseshoe crab)
Jointed legs
Segmented bodies
First to learn how to fly
Describe the characteristics and give an example of the animal phylum Chordata.
Example: amphioxus, cartilage fish (sharks), bony fish, amphibians, reptiles, birds, mammals Dorsal, hollow nerve cord Notochord (spinal column) Segmented bodies Some Chordates do not have a backbone
Characteristics of fish.
Gills
Paired fins
Ectothermic
Characteristics of amphibians.
Most have lungs Legs Water permeable skin Main respiratory organ is the skin Larval stage begins in water (some exceptions)
Characteristics of reptiles.
Dry skin Amniotic egg (hard shell, allows storage of waste and nutrients)
