Science Kids: All About Cells

The video explores the fundamental role of cells in living organisms, highlighting their structure, functions, and the vast number of cells in the human body. It distinguishes between plant and animal cells, explaining unique features like vacuoles and cell walls. The processes of cell division, mitosis, and meiosis are detailed, emphasizing their roles in growth and reproduction. The video also covers cell specialization and organization into tissues, organs, and systems, illustrating how cells contribute to the complex functions of living organisms.
