1 Introduction to Animals Chapter 9 Section 1-2

2 What is an Animal? Eukaryote Heterotroph Multicellular ◦ Cells are usually arranged into tissues  (muscle tissue) ◦ Tissues are arranged into organs  (heart) ◦ Organs are arranged into systems  (circulatory system)

3 Functions of Animals 1. Obtain food and oxygen 2. Maintain stable internal conditions 3. Movement 4. Reproduction ◦ (Vocab to remember: sexual reproduction, asexual reproduction, fertilization)

4 Animal Symmetry Symmetry: balanced arrangement of parts Two types ◦ Bilateral - One line divides into halves that are mirror images (Isosceles triangle) ◦ Radial – many lines of symmetry that all go through a central point (circle) Asymmetry – no symmetry

5 Animals with Radial Symmetry Parts arranged around a center point Live in water Don’t have a front or back end Do not move fast

6 Animals with Bilateral Symmetry More complex Have a front end Move more quickly Most have sense organs on front end (eyes, whiskers, nose, ears)
