Summary Introduction

Introduction: Animals are multicellular eukaryotes and have heterotrophic (ingest food and digest them by certain digestive enzymes) mode of nutrition. They lack cell wall and the cells are connected to each other with the help of the collagen (extracellular matrix) and various structural proteins located outside the cell membrane. Animals have highly developed sensory and nervous systems.
