The Nucleus,odent) for mammalian species. Some polyploid species of plants and invertebrates have several hundred chromosomes. A direct relationship between chromosome ploidy and nuclear size is found in some species, e.g. the sea urchin, but not in others. In fact, there are many examples that show that nuclea

Plastids and Chloroplasts,radish seedling is shown in figure 3.1 to illustrate the variety of plastids in its tissues. The chloroplasts—plastids whose internal membranes contain chlorophyll—are functionally and structurally the most complex plastids and, because of their unique role in mediating photosynthesis, have been the

Mitochondria,outer membrane or envelope enclosing an inner membrane which has tube-like invaginations (cristae) into an inner compartment (the matrix). The cristae membrane of liver mitochondria (figure 4.1) is 3–4 times greater than the outer membrane area. Some mitochondria, particularly those from kidney, hea

Organelles and Neuromuscular Activity,ion are brought about by the neuromuscular system, the activity of which is also dependent on specialized cell organelles that are associated with ER and Golgi bodies, namely the synaptic vesicles of neurones and the sarcoplasmic reticulum of muscle. These organelles, together with the chromaffin gr

New and exciting information about all these structures has emerged in recent years-for example, the nucleosome, interrupted genes, signal sequences on proteins destined for the bioenergetic organelles, mapping and sequencing of organelle genes, and cons
