3. Tissues: Plant and Animal Tissues

Tissues are defined as a group of similar cells working together to carry out specific functions, forming the basic organization in multicellular organisms. Plant tissues are categorized into meristematic and permanent tissues, while animal tissues consist of epithelial, connective, muscular, and nervous tissues. Understanding the differences between plant and animal tissues is crucial in studying how organisms function and survive.
