This document provides an introduction to cell structure and shape. It discusses the aims of studying cells, including learning about their basic information, structure, and what determines their shape. Specifically, it explores the roles of the cytoskeleton, shapes of bacterial, fungal, plant and animal cells, and how different shapes impact functions like blood cells, neurons, muscles and more. Next steps will discuss how cell dimensions are determined.

The cytoskeleton has three distinct elements

8. Cytoskeleton
Function of cytoskeleton
1. Maintenance of cell shape.
2. Chromosome movement in cell division
3. Cell motility.
4. Serving as highways for transport of secretory vesicles
within cell as well as movement of substances from one
place to another place of the cell.
5. Muscle contraction
