    Study Notes

    Animal Structure and Function

    • Animal form and function are correlated at all levels of organization, meaning that an animal's size and shape affect how it interacts with its environment.

    Body Plans and Size

    • Different animal body plans have evolved and are determined by the genome.
    • The ability to perform certain actions depends on an animal's shape, size, and environment.

    Environmental Constraints

    • Physical laws impose constraints on animal size and shape.

    Exchange with the Environment

    • An animal's size and shape directly affect how it exchanges energy and materials with its surroundings.
    • In single-celled organisms, exchange occurs through the cell membrane (0.15 mm).
    • In simple multicellular organisms with a sac body plan, the body walls are only two cells thick, facilitating diffusion of materials (1.5 mm).

    Complexity and Internal Surfaces

    • More complex organisms have highly folded internal surfaces for exchanging materials.
