Organization of Animals
Basic unit of structure and function makes up all living things?
Cell
Three types of body symmetry
bilateral, radial, none
Phyla of sponges
Porifera
Phyla of cnidarians
Cnidaria
9 animal phyla in order
Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda, Echinodermata, Chordata
Group of cells that perform a specific function
Tissue
All animal phyla with no body symmetry
Porifera
Cells that collect food using flagella and amoebocytes
collar cells (coanocytes)
4 examples of cnidarians
jellyfish, hydra, coral, sea anemone
4 main functions of animals
obtaining food and water, maintaining stable internal conditions, movement, reproduction
Group of tissues that performs a more complex function
Organ
All animal phyla with radial symmetry
Cnidaria, Echinodermata
Holes in a sponge through which water is filtered and opening in the top through which water exits
pores; osculum
2 body plans of cnidarians and each plan's shape
polyp - vase-like
medusa - bowl-like
Action of maintaining stable internal conditions
homeostasis
Example of an organ system
Nervous system, bones, muscles
All animal phyla with bilateral symmetry
Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda, Chordata
Glassy cells that are used to classify a sponge
spicules
stinging cells in cnidarians
Cnidocytes
Meaning of the name of each phyla
Porifera - having pores; sponges
Cnidaria - stinging celled; jellyfish, hydra, coral, sea anemones
Platyhelminthes - flat worms; planaria, flukes, tapeworms
Nematoda - round worms; hook worms, pin worms
Annelida - segmented worm; earth worms, leeches, fan worms
Mollusca - soft bodied; clams, oysters, octopi, squid, snails, slugs, scallops, cuddlefish
Arthropoda - jointed legs; crabs, insects, lobsters, centipedes, spiders, millipedes, crustaceans
Echinodermata - spiny skinned; sea urchins, star fish, sand dollars
Chordata - have notochords/backbones; mammals, reptiles, birds
9 parts to the organization of animals, starting with cells
cells, tissues, organs, organ systems, organism, population, community, ecosystem, biosphere
One example of an organisms with each type of body symmetry
Radial: sea anemone, jellyfish, starfish, sand dollar, coral polyp
Bilateral: any mammal, reptile, bird, worm, fish, etc.
None: any type of sponge (barrel sponge, bath sponge, tube sponge, harp sponge, etc.)
5 ways sponges are ecologically important
filter water, control populations, provide camouflage, provide habitats, provide food
5 things cnidarians did/had before any other animal
stomach (gastrovacular cavity), move as adults, fight for territory/compete with each other, have nerves, cooperate
Name for the top, bottom, front, and back sides of an organism
dorsal, ventral, anterior, posterior
