Introduction to Tissues

The video tutorial explains how a single cell divides into trillions of genetically identical cells, yet differentiates into over 200 types with specialized functions. It compares unicellular and multicellular organisms, highlighting the need for cell differentiation. The tutorial discusses specialized cells forming tissues, and the differences between plant and animal tissues. It covers plant tissue types, including meristematic and permanent tissues, and animal tissue types, such as epithelial, muscular, connective, and nervous tissues.

What roles do epithelial tissues play in the body?

Explain the function of muscular tissues in animals.
