40 basic principles of animal form & function. Concept 40. 1: animal form and function are correlated at all levels of organization: physical laws, especially physics of exchanging materials with environment, limits range of animal forms. Clicker question: is this possible here on earth? (star wars Exchange in simple organisms (figure 40. 3: single-celled organisms. Entire plasma membrane is exposed to medium: multicellular organisms with a sac body plan. Body wall is only 2 cell-layers thick. Exchange in complex animals (figure 40. 4: large, complex animals have highly folded or branched internal surfaces specialized for exchanging materials, this increases surface area. Epithelial tissue (figure 40. 5: covers the outside of the body and lines the organs and cavities within the body, cells are closely joined. Connective tissue: functions mainly to bind and support other tissues, composed of sparsely packed cells scattered throughout an extra cellular matrix, major types.
