Understanding Cells and Organisms

The video tutorial introduces cells as the basic unit of life, discussing their discovery by Robert Hooke. It explains cell division and its role in replacing damaged cells, as well as how uncontrolled division can lead to cancer. The tutorial explores the structures and functions of animal and plant cells, highlighting their similarities and differences. It also compares unicellular and multicellular organisms, providing examples of each. The video concludes with a review of key concepts and practice questions to reinforce learning.
