    Functions and structure of plant terpenes Terpenes are an enormous class of organic compounds, that are produced by a wide variety of plants and fungi, especially conifers. Terpenes are also produced by some of the living organisms, like swallowtail butterflies. They emit terpenes from their osmeterium. Terpenes are important materials for a plant as components of its body and as a material to protect it from external enemies since it has a strong smell and colorless. Terpenes are found in biological…

    Plants Organs As was noted in the previous chapter, most plant cells are specialized to a greater or lesser degree, and arranged together in tissues. A tissue can be simple or complex depending upon whether it is composed of one or more than one type of cell. Tissues are further arranged or combined into organs that carry out life functions of the organism. Plant organs include the leaf, stem, root, and reproductive structures. The first three are sometimes called the vegetative…

    Chapter 3 Cell Structure and Function Section 3.1: Cell Theory: Cells are the smallest building unit of living organisms that can carry out all processes required for life. Almost all cells are too small to see without the aid of a Microscope. Although glass lenses used to magnify images for hundreds of years, they were not enough to reveal individual cells. The invention of Compound microscope was in the late 1500s by the Dutch eyeglass maker Zacharias Janssen. In 1665, the English scientist…
