    Study Notes

    Animal Classification

    • Cats are vertebrates, possessing a backbone. Vertebrates have backbones; invertebrates do not.

    Biological Organization

    • Unicellular Organisms: Organisms composed of a single cell.
    • Multicellular Organisms: Organisms composed of more than one cell.
    • Cellular Differentiation: The process where cells specialize for specific functions.
    • Specialized Cells: Cells with specific tasks.

    Levels of Organization (Increasing Complexity)

    • Cells
    • Tissues
    • Organs
    • Organ Systems
    • Organisms

    Animal Tissues

    • Connective Tissue: Supports and binds other tissues (e.g., bone, blood, lymph).
    • Epithelial Tissue: Forms coverings (e.g., skin, inner linings).
    • Muscle Tissue: Enables movement.
    • Nervous Tissue: Transmits signals to the brain.

    Differentiated Cells

    • A differentiated cell is a specialized cell with a specific function (e.g., a blood cell carrying oxygen).

    Human Organ Systems

    • Circulatory
    • Digestive
    • Musculoskeletal
    • Respiratory
    • Nervous

    Gas Exchange (Humans vs. Frogs)

    • Humans: Inhale air, which travels through the trachea, bronchi, and bronchioles to alveoli where gas exchange (oxygen uptake and carbon dioxide release) occurs.
    • Frogs: Under water, frogs' skin can absorb oxygen. They can also breathe through the mouth.

    Plant Transport

    • Plants transport water and minerals from roots to leaves via the xylem. Factors include root pressure, capillary action, and transpiration pull (water evaporation through stomata).

    Photosynthesis

    • Some organisms performing photosynthesis include algae, trees, flowers, and other plants.

    Paramecium Cilia

    • Paramecia use cilia (hair-like structures) to move through water and ingest food.

    Unicellular Phagocytosis

    • Unicellular organisms use phagocytosis (engulfing food particles) to obtain nutrients. This forms a food vacuole where enzymes break down the food.

    Organ Systems Table

    • (Note: The provided table is incomplete and may need further details for a full study aid.)*
    Organ System Function Example Organs
    Circulatory Transports oxygen to the body Heart, blood vessels
    Respiratory Supplies oxygen for breathing Nose, trachea
    Digestive Breaks down food consumed Mouth, stomach
    Musculoskeletal Provides body support Bones
    Nervous Sends signals to the brain Brain

    Environmental Responses

    • Vertebrates: Respond to the environment using the nervous and musculoskeletal systems (e.g., pain response, movement).
    • Trees: Responding to cold/dry weather by shedding leaves to reduce water loss.

    Major Organism Groups

    • Fungi
    • Bacteria
    • Animals
    • Plants
    • Protists
