Cell Anatomy
A good topic to start off with is basic anatomy. Some organisms, including humans, have millions of cells in their body, while others have only one cell. No matter how many cells are in a single life form, each possesses a similar function, just like the organs in a human body. For example, the mitochondria, the second largest part of a cell, serve as the cell's digestive system. It breaks down carbohydrates, fats and protein so the cell can use it to perform different tasks.
Biological Activities of Cells
Related to understanding cell parts, the different biological activities happening within a cell is important. Aside from breaking down proteins and sources of energy, cells recycle certain chemicals and produce specific proteins so the body can function and maintain itself. There are also special cells that perform specific functions. For example, in humans, white blood cells are biologically designed to be a natural protection against infection and other complications.
Cells and Genetics
Deoxyribonucleic acid, DNA, is a special molecule found in a cell's nucleus that contains all of a living organism's genetic information. DNA contains the data on how a living organism looks, what internal systems it builds and what types of cells are produced. It is considered life's biological rulebook allowing cells to know how to break down proteins and create other chemicals. Understanding DNA is also related to genetic engineering, the science where DNA is modified for medicinal and scientific purposes.
Laboratory Experiments
Several laboratory experiments are beneficial to learning the ins and outs of cellular biology. Some experiments can be difficult as they require technical knowledge, such as culturing cells or operating a complex microscope, although even a simple compound microscope can be used to view cells and their anatomies. More advanced cell splicing and genetic modification can also be performed given the right set of tools, such as micro-machines and enzymes.
