Definition - What does Molecule mean?

A molecule is the name applied to bonded groups of atoms. These form the building blocks of everything, from rocks and soil to trees and human beings. In living things, molecules join together to form cells. In plants, those cells eventually form an entire plant. Plant molecules are unique from those of other living things in many ways, including having the ability to manufacturer their own food.

While atoms might be considered the building blocks of all things, only when they are bonded together do we get the ingredients for life. Molecules (groups of bonded atoms) come in many different forms. When they are combined, molecules form cells. Plant cells are similar to those of fungi and other eukaryotes, but they have several key differences. For instance, plant molecules lack cilia and intermediate filaments. They also lack centrioles and flagella, as well as lysosomes.

Plant molecules, as a broader term, also applies to elements beyond the cells that make up a plant’s physical body. For instance, growth regulators like auxins, which are molecules naturally found in plants, are manufactured within their cells but can also be synthetically derived molecules that can be applied to seeds and plants to support stronger growth. Auxin is more heavily concentrated and manufactured in heavier concentrations within certain parts of the plant, including the meristems and new growth shoots.

There are many other molecules within plants, such as macromolecules comprised of multiple smaller molecules. These smaller components are most often hydrogen, oxygen, and carbon. You’ll find a number of macromolecules at work within plants, including carbohydrates, fats, and oils.
