Term
Eukaryotic
Definition
Has a nucleus and organelles
Term
Heterotrophic
Definition
Feeds off of others
Term
Herbivores-
Carnivores-
Omnivores-
Parasites-
Filter Feeders-
Saprotrophs/Detrivores-
Definition
Autotrophs
Heterotrophs
Both
Extracts food from water
Decomposers
Term
Specialization
-(And advantages)
-(And disadvantages)
Definition
Specialized cells for all animals and specialized tissues for most animals
-more efficient
-increased interdependence
Term
Glycogen
Definition
The large molecules that animals store their extra glucose
Term
All animals undergo embryonic development starting w/a zygote, then through the blastula and gastrula stages.
Definition
Term
Symmetry
Definition
The arrangement of body parts around a central axis
Term
Asymmetry
Definition
No symmetry
Term
Radial Symmetry
Definition
Can be divided into equal parts at many planes along the central axis (like a pizza).
Term
Adavantage of Sessile organisms with radial symmetry
Definition
They can feed it all directions
Term
Bilateral Symmetry
Definition
Anterior- Front side
Posterior- Back side
Ventral- Lower side
Dorsal- Upper side
Term
Cephalization
Definition
The concentration of nerves and sensory tissue/organs at the anterior portion of bilateral organisms (possesses a head).
Term
Endoderm
Definition
Will develop into the tissues/organs of the digestive (food and water) and respitory (air) tracts
Term
Ectoderm
Definition
Will develop into the tissues/organs of body coverage (feathers, fur, claws, skin) and nervous system
Term
Mesoderm
Definition
Will develop into the tissues/organs of muscles and skeleton (not found in Porifera or Cnideria).
Term
Steps of Embryonic Development
Definition
1. Fertilization
2. Zygote
3. 2 celled zygote
4. 4 celled zygote
5. Morula
6. Blastula
7. Gastrula
Term
Body Cavity
Definition
Fluid filled spaces that lie between the digestive tract and the body wall. Body cavities provide a space for organs to grow and move without being twisted or crushed during body movement. Body cavities, being lined by membranes, isolates infection and specific organ function.
Term
Acoelomates
-Examples
Definition
Animals lacking a body cavity
-Porifera- Sponges, Cnideria- Jellyfish, Platyhelminthes- Flatworms
Term
Pseudocoelomates
-Examples
Definition
Animals with a body cavity located between the mesoderm and the endoderm
-Nematodes- Roundworms
Term
Eucoelomates
-Examples
Definition
Animals that have a body cavity that develops within the mesoderm
-All other animals
Term
Protostomes
Definition
Blastopore (area of indent in the gastrula) becomes the mouth
-Cnideria- Arthropods
Term
Deutrostomes
-Examples
Definition
Blastopore becomes the anus
-Echinoderms and Chordates
Term
Direct Development
-Examples
Definition
Offspring are smaller versions of an adult
-Snakes, Cows, Cats
Term
Indirect Development (metamorphosis)
Definition
Offspring undergo physical changes before becoming an adult
Term
Incomplete Metamorphosis
Definition
Egg-->Larvae/Nymph-->Adult
Larvae will have a similar body form to the adult, but will lack sexual organs and adult structures (like wings).
Term
Complete Metamorphosis
Definition
Egg-->Larvae-->Pupa-->Adult
The developing organism (larvae) will undergo dramatic changes during the pupa stage and will differ in shape and diet from the adult.
Term
Invertebrate Phyla
Definition

Term

Definition
Term
Phylum Porifera
Definition
-Advance- Multicellular
-Asymmetrical
-Possesses no tissues or organs
-Sexual or Asexual reproduction
-Hydrostatic Skeleton
-High regeneration ability
-Sessile (adult). Mobile (larvae).
Term
Phylum Cnideria
Definition
-Advance- They have tissues (ectoderm, endoderm).
-Radial Symmetry
-Acoelmates with two germ layers (ecto and endoderm) which surrounds the mesoglea
-Possesses nerve net
-All cnidarians live in water, most marine. Many have tenticles with cnidocytes (use to capture prey which makes them carnivores).
-The thin cnidarians move water, nutrients, and waste products through their body via diffusion
-Hydrostatic Skeletion
-Asexual or sexual reproduction
-Either a Polyp (sessile stage) or a Medusa (mobile stage).
Term
Phylum Platyhelminthes
Definition

Advance- 3 germ layers

-Flatworms- Bilateral symmetry, cephalization, and organs

-Flatworms are unsegmentred acoelomates with all three germ layers

-Most are parasitic and/or carnivores (flukes and tapeworms).

-Move nutrients, water, oxygen, and waste via diffusion and an extensive digestive cavity (have a one way digestive tract with mouth and anus).

-Hydrostatic skeleton

-Primitive nervous system

-Most are herm's

-Some are asexual

Term
Phylum Nematoda
Definition

-Advance- Pseudocoelem

-Unsegmented roundworms which taper at the ends

-Bilateral Symmetry

-Hydrostatic skeleton

-Parasitic and carnivores

-Different sexes which are both asexual and sexual

Term
Phylum Mollusca
Definition

-Advance- They have a coelem

-Least advanced of the eucoelomates

-Bilateral symmetry

-Hydrostatic skeleton or exoskeleton

-Protostomes

-Head- Contains sense organs

-Visceral Mass- Internal Organs

-Foot- For movement

 

Term
Gastropods (snail, slug)-
Definition
-Foot to crawl, mantle secretes a hard shell, herbavores
Term
Bivalves (oyster, clam, scallop)- 
Definition
-Secrete two part shell w/a hinge, fliter feed
Term
Cephalopods (octopus, squid)-
Definition
-Have a modified mantle cavity to create jet propulsion for rapid movement
Term
Open Circulatory System
Definition
