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.
