Unit 7: Cell : The unit of life

About this unit

Why do we need to learn about cells? The cell is fundamental to all life. All diseases, for example, Alzheimer’s, dengue, diabetes, cancer, TB, etc., are caused at the cellular level. Understanding how the cell works helps us find better treatments for diseases. Besides diseases, there are many other applications of cell biology. Studying the DNA of ancient skeletons that have been dug up, making better crops, solving murders, and many more! In this unit, learn how cells of all organisms - from bacteria to human beings - are essentially similar, and how they work.
