Importance Of Learning Biology Terminology

In most sciences, including biology, there is a preponderance of new terminology that must be learned quickly and remembered. Research suggests that students who are knowledgeable of biological terminology do much better in standardized testing including the EOC, ACT, and PSAT tests. It is helpful that students learn to recognize word parts which usually give a clue to the meaning of the entire word. Identifying common prefixes and suffixes in a word allows students to relate them to the definitions. In biology, there are many suffixes and prefixes commonly used. After their meanings are memorized, it will become easier to remember and learn new terminology.


Meaning Of The Prefix 'Meso'

Meso is a prefix (a group of letters added before a word to alter its meaning and form a new word) which means middle, between, partially, or intermediate. It is derived from the ancient Greek word 'mesos' meaning 'middle'. Meso, as a prefix, is extremely common in scientific nomenclature including biology.

When the prefix meso comes before a noun it often refers to a spatial relationship, signifying location. For example, the word mesoderm refers to the middle layer of the skin and the word mesosphere refers to the middle layer of the atmosphere. The prefix meso can also refer to a temporal relationship. The word mesozoic means middle life and relates to a middle stage of earth's evolutionary history.

The prefix meso also occurs in biochemistry nomenclature. A meso is a substance having bilaterally symmetrical structure. It also has two or more atom groups not consisting of hydrogen. Tantaric acid, found in grapes, is a meso compound.
