Study Notes
Chapter 10 Study Guide
- Animal Characteristics: All animals are eukaryotic, consumers, and most can move.
- Animal Classification: Scientists use symmetry (bilateral, radial, asymmetry), presence of body cavities (complete or incomplete), and cephalization to classify animals.
- Symmetry Types:
- Bilateral symmetry: Organisms can be divided into two mirror-image halves (e.g., crab).
- Radial symmetry: Organisms can be divided into multiple mirror-image halves (e.g., starfish).
- Asymmetry: Organisms cannot be divided into mirror-image halves (e.g., tube sponge).
- Invertebrates vs. Vertebrates: Vertebrates have a notochord (backbone); invertebrates do not.
- Invertebrate Groups: Sponges, cnidarians, worms, echinoderms, mollusks, and arthropods.
- Examples:
- Sponges: No symmetry, no cephalization, no gut
- Cnidarians: Radial symmetry, stinging cells (cnidocytes)
- Echinoderms: Radial symmetry (e.g., sea stars, sea urchins).
- Mollusks: Include gastropods (snails), cephalopods (octopus), bivalves (oysters).
- Arthropods: Diverse group (e.g., insects, crustaceans)
- Examples:
Chapter 11 Study Guide
- Organ System Functions: Be familiar with the functions of digestive systems (mechanical and chemical digestion) and other systems.
- Digestion:
- Mechanical digestion: Breaking down food using teeth or gizzard.
- Chemical digestion: Breaking down food using chemicals.
- Digestive System Organs: Mouth, esophagus, liver, stomach, gall bladder, pancreas, small and large intestines, anus.
- Animal Adaptations to Food: Herbivores (plants), carnivores (meat), omnivores (both), filter feeders (straining small things).
- Excretion System: Kidneys and bladder.
Chapter 12 Study Guide
- Reproductive Organs: Sperm and eggs.
- Internal vs. External Fertilization:
- Internal fertilization: Sperm and egg unite inside the female.
- External fertilization: Sperm and egg unite outside the body.
- Internal vs. External Development:
- Internal: Fertilized egg develops inside the female.
- External: Fertilized egg develops outside the body.
- Innate vs. Learned Behavior:
- Innate: Behaviors an animal is born with (e.g., reflexes).
- Learned: Behaviors an animal learns (through observation).
- Reflex vs. Instinct:
- Reflex: Quick, automatic response to a stimulus.
- Instinct: Complex behavior pattern (e.g., building a nest).
- Animal Communication: Sound, sight, touch, chemicals.
