This book explores the structures of planet and animal cells, takes a look at how cells function and discusses the role of they play in supporting all living organisms. It also examines the role of DNA, what happens when cells mutate and examines cutting-edge developments in the scientific investigation of cells, such as stem cell research. Includes investigations that show how to study different cells under a microscope and fascinating fact boxes that offer in-depth information on topics such as fertilisation. An activity project shows students at Key Stage 3 how to create a model of a plant cell. The six books in the Living Processes series look at the processes all living organisms must carry out in order to stay alive. From feeding and drinking through to breathing and reproducing, it explores the differing ways in which organisms carry them out.
