Matter

Robert Barrass

Scientists use the term matter to include all materials. Matter is defined as anything that occupies space. And a space from which all matter has been removed is called a vacuum. Matter exists in three states: 1 A solid has both a definite shape and a definite volume, it occupies a fixed amount of space. 2 A liquid has a definite volume but not a definite shape, it takes the shape of its container. 3 A gas has neither a definite shape nor a definite volume, it takes the shape and occupies the volume of any container.

The use of matter and energy in your body

Robert Barrass

The different kinds of molecule made by green plants (including carbohydrates, lipids, proteins and vitamins) are present in the food of animals. They are digested and smaller molecules are absorbed. Because of its length (about 7 m) and the presence of finger-like processes, the villi (see Figure 19.2), your small intestine has a very large surface area of epithelial cells absorbing the products of digestion. When molecules absorbed after digestion become part of the cells and tissue fluids of your body, they are said to have been assimilated.

Vocabulary for introductory courses in biology: necessary, unnecessary and misleading terms

Journal of Biological Education (1979)

Robert Barrass

Abstract Biology is overloaded with technical terms. More than 1500 terms are used in one introductory text. However, for the beginner, many of these terms are unnecessary and should be discarded. In this paper an attempt is made to recognize the misleading, obsolete, and otherwise unnecessary terms that are in common use, even in syllabuses and examination papers. Lists are also included of the terms that teachers are likely to need for introductory courses.
