Elements of Structural and Systematic Botany: For High Schools Elementary College Courses

is a scientific publication written in the late 19th century. This work serves as an introduction to the study of botany, primarily in tended for high schools and early college courses, emphasizing structural and systematic aspects of the science. The book aims to provide a com prehensive understanding of plant anatomy, morphology, andclassification while distinguishing the essential elements of botany from mere identifica tion.

Campbell highlights the importance of not just knowing plant names but grasping the underly ing structure and relationships within the plant kingdom. He discusses the foundational concepts of botany, includingtheclassification system and the tools required for studyingplants, suchasmicroscopes. Overall,thetextsets the stage for a deeper exploration of plant biology, aiming to equip students with both theoretical knowledge and practical skills in botany allmatter iscomposedofcertainconstituents(aboutseventyareatpresent known),which,sofarasthechemistisconcerned,areindivisible,andare known aselements.

While it is impossible, owing to the dependence of all organized matter upon inorganic matter, to give an absolutedefinition, weatoncerecognizethepeculiaritiesoforganicorliving bodies as distinguished from inorganic or non-living ones. All living bodies feed, grow, and reproduce, these acts being the result of the action of forces resident within the organism. Inorganic bodies, on the other hand, remain, as a rule, unchanged so long as they are not acted upon by external forces. All living organisms are dependent for existence upon inorganicmatter,and sooneror laterreturntheseelementstothesourceswhencetheycame. Thus, a plant extracts from the earth and air certain inorganic compounds which are converted by the activity of the plant into a part of its own substance, becoming thus incorporated into a living organism.
