Specialized Cells in Plants and Animals: Functions and Features

Mr. Bebe's lesson covers specialized cells, highlighting the differences between plant and animal cells. It explains how specialized cells perform specific functions and originate from stem cells through differentiation. The video details various specialized animal cells, such as red and white blood cells, epithelial, and muscle cells, and their roles. It also explores specialized plant cells, including root, vascular, leaf, and guard cells, and their functions in plants.
