New cells are formed from pre-existing cells by cell division, this lecture is an introduction to this process of cell division. The key components are: cell cycle, mitosis, meiosis. The lecture slides and textbook alone contain enough information as an introduction to the subject for this level of study. If you are interested in further reading, I have also included below links to more detailed textbooks with further information and images.
Understand the concept of cell lifespan
Understand generally how cells are born and die
Understand the concept of cell cycle
Understand the major steps in mitosis
Brief understanding of abnormalities of cell division
Broad understanding of the 2 types of eukaryotic cell division- mitosis and meiosis

This page gives an introduction to Cell Division. In the Lecture we will go through in some detail concepts of cell lifespan, cell cycle, mitosis and abnormal cell division. Other topics such as cell death, cell cycle regulation and meiosis will only be briefly covered.
Note that cell cycle can be covered by sometimes several chapters in any good Cell Biology textbook, meaning that no detailed coverage can be given in any one lecture. Science students (see lecture links) receive several lectures to cover aspects of this topic.
A major difference between eukayotes and prokaryotes is the timecourse of cell division and its regulated.
As an introduction to the topic, only a broad understanding of how new cells are made is required, but by all means research the topic as deeply as you would like :-)
