unit 10 notes 8 Flashcards
What is the animal kingdom like?
- Cells are eukaryotic
- Multi-cellular
- have specialized cells that form tissues and organs
What phylum is this?
Sponges, soft bodied, asymmetrical, invertebrates, Non-motile - hold fasts, fliter feeders, reproduce sexually and asexually, Hermaphrodites - produce both egg and sperm
Phylum Brifera
What phylyum is this?
- Jellyfish, coral, sea anemones, and hydra
- radial symmetry, has 2 stages of life - polyp and medusa, predators that poison their prey, digest food in the gastrovascular cavity, oxygen diffueses into cells, reproduce sexually or asexually
phylum Cnidaria
What phylum is this?
- Tapeworms and planerians
- soft-bodied, has a simple nervous system and muscle system, has a basic mouth to help feed, some parasites, can regenerate - can grow new parts
Phylum Platyhelminthes
What phylum is this?
- Hookworms, pinworms, roundworms, and ascaris
- many are parasites, have tube like digestive systems, have 2 openings - a mouth and a anue
phylum Nematoda
What phylum is this?
- slugs, snails, squid, octopi, and clams
- bilateral symmetry, some have shells, open circulatory system - the blood flows freely, not in veins or arteries
phylum molluska
what phylum is this?
- segmented worms - bodies have segments, earthworms, leeches, bistleworms
- Have setae - small bristles that help with movemnet, Digest food in a gizzard (simple stomach), have a closed circulatory system - heart and blood vessles, nervous system - simple brain and nerve cord
Phylum annelida
What phylum is this?
- Insects, crustaceans (lobster and crabs), and arachnids (spiders and ticks)
- Invertebrates, bilateral symmetry, exoskeleton, molting - shed their exoskeletons, appenages - jointed structures such as leg and antennas
Phylum Arthropods
what phylum is this?
- sea stars, brittle stars, sea urchins, sand dollars, and sea cucembers
- radial symmetry, many have tube feet, water vascular - uses water pressure to help with movment, feeding, and removing waste
phylum echinoderms
What phylum is this?
- Fish, amphibians, reptiles, birds
- vertebrates, developed nervous systems
phylum chordata
What are the 5 catagories in phylum chordata?
Fish, amphibians, reptiles, birds, and mammals
what are fish like?
boney fish - have a swim bladder (fills with gas and allows them to control their depth in the water)
Sharks - bones made of cartilage (soft bone), most sharks give live birth but some lay eggs
What are amphibians like?
- Frogs, toads, salamanders
- 4 legs, moist skinthat can help with breathing, lay eggs in water, spend their early life in water and their later life on land, Ectotherms (cold blooded)
What are reptiles like?
- Snakes, turtles, alligators, and lizards
- scaly skin (not used for breathing), reproduce on land, ectotherms
What are birds like?
Endotherm (warm blooded), Incubate their eggs - sit on them to control their temperature
what are mammals like?
Endotherms, have hair, have glands (sweat glands, saliva, and mammary glands), nurse their young, have varied teeth for cutting and grinding food, modified limbs, can learn
