In our bodies, for example, muscle cells produce movement and nerve cells (neurons) are communication specialists. In this module your goal is to understand the important structural components of cells and how these subunit work together in carrying out life processes.
Electron microscopy and biochemical analysis have revealed that a cell actually contains tiny specialized structures called organelles that perform specific cellular functions. Today, we are accustomed to thinking of living things as being constructed of cells. But the word cell didn’t enter biol-ogy until the seventeenth century.
Describe the structure and functions of the different components of human body cells. Describe the two types of cell division: meiosis for the formation of gametes for reproduction, and mitosis involved in growth and development.
