Study Notes
Animal Kingdom Classifications
- Vertebrates have a backbone
- Invertebrates do not have a backbone
- Pseudocoelomates are a type of invertebrate with a pseudocoelom, a fluid-filled cavity between the endoderm and mesoderm
- Acoelomates are a type of invertebrate without a true body cavity
Body Structure
- Endoskeleton: internal structure of bone
- Exoskeleton: tough plate on the outside of the body
Life Processes
Nutrition
- Ingestion: intake of food
- Digestion: breaking down of food
- Assimilation: absorbing nutrients
- Elimination: expelling wastes
Movement and Locomotion
- Motile: able to move around
- Sessile: stationary
Respiration
- Exchanging oxygen and carbon dioxide
Circulatory Systems
- Open Circulatory System: hemolymph flows from vessels into the body cavity
- Closed Circulatory System: blood is contained in vessels
Reproduction
- Asexual reproduction: budding and regeneration
- Sexual reproduction: involving sex cells
Response to Stimuli
- Stimuli: external factors that elicit a response
