The Experimental Study of Organelles,e to them. we will make frequent references throughout this book to the experimental methods described in this chapter, which is best used as a resource to be consulted, rather than to be read from beginning to end.

The Nucleus, and around the cell, one could amply justify the assertion that the nucleus is the control centre of the cell. Despite this functional significance, we know relatively little about the structural organisation of the nucleus.

The Endoplasmic Reticulum,ng homogenisation of tissue samples. The resulting .’ can be readily prepared by centrifugation (section 2.2.1). As we shall see, microsomes have been widely used as cell-free model systems for studying many of the biosynthetic processes mediated by the ER.

The Peroxisome,uct of their reaction (figure 7.1). Thus, it was considered that the peroxisome had developed in the course of evolution in order to protect the cell from the potentially harmful effects of these particular oxidative enzymes.

Dynamic Interactions Between Organelles,hich encode them, at the expense of lipids and carbohydrates, which are nevertheless major cellular components. Finally, the impression may have been given that the cell, with all its organelles, is a self-enclosed entity isolated from its environment. Nothing could be further from the truth.

Ultrastructure of the Cell,ith such instruments, they were able to describe the vast range . of eukaryotic cells, the association of specialised cells into tissues and organs, and some of the subcellular architecture of the cell.
