AP Biology Period – 4 #22 Liem Nguyen 3/6/10 Homework #40 (090320): Chapter 40 (due Friday 090320) Total points: 40 for Attempt on all questions Concept Map: 10 Points Chapter 40: Basic Principles of Animal Form and Function Objectives Functional Animal Anatomy: An Overview 1. Define bioenergetics. A basic concept Organisms obtain, process, use energy Resources and connecting theme Comparative study of animals Bioenergetics is a concept. It is the concept of how organisms obtain, process, and uses the energy resources provided to them. This is a connecting theme in the comparative study of animals. 2. Distinguish between anatomy and physiology. Explain how functional anatomy relates to these terms. Differ in their definitions Anatomy: study of creature’s structure Physiology: study of creature’s function Functional: affect of structures and functions Anatomy and physiology differ in their definitions. Anatomy is the study of structure of a creature. Physiology is the study of the function of a creature. Functional anatomy would be the study of how certain structures of an organism are used in the organism's function. Body Plans and the External Environment 3. Explain how physical laws constrain animal form. Size and shape “body plants” Fundamental aspects to form and function Genome and evolution changed physical requirements Many constraints based on environment An animal's size and shape, features often called "body plants" or "designs," are fundamental aspects of form and function that significantly affect the way an animal interacts with its environment. The terms plan and design to not mean that animal body forms are products of conscious invention. The body plan or design of an animal results

from a pattern of development programmed by the genome, itself the product of millions of years of evolution due to natural selection. Physical requirements constrain what natural selection can "invent." An animal such as the mythical winged dragon cannot exist. No animal as large as a dragon could generate enough lift to take off and fly. Similarly, the laws of hydrodynamics constrain the shapes that are possible for aquatic organisms that swim very fast. 4. Explain how the size and shape of an animal’s body affect its interactions with the environment. Size and shape have direct effect Animal exchanges energy and materials Fluid integrity of plasma membrane of cells Dissolved substances diffuse and transported Protist has sufficient surface area of membrane Surface to volume concept ration An animal's size and shape have a direct effect on how the animal exchanges energy and materials with its surroundings. As a requirement for maintaining the fluid integrity of the plasma membrane of its cells, an animal's body must be arranged so that all of its living cells are bathed in an aqueous medium. Exchange with the environment occurs as dissolved substances diffuse and are transported across the plasma membranes between the cells and their aqueous surroundings. For example, a single-celled protist living in
