This document discusses how understanding common prefixes and suffixes in biology can help make complex biology terms easier to understand. It provides examples of breaking down 7 biology words – autotroph, cytokinesis, eukaryote, heterozygous, hydrophilic, oligosaccharide, and osteoblast – into their discrete linguistic units. Understanding the meaning of these units helps reveal the overall meaning of the full word. The document encourages readers to practice this word dissection technique on additional examples to gain familiarity with interpreting multi-part biology terminology.
One of the keys to being successful in biology is being able to understand
the terminology. Difficult biology words and terms can be made easy to
understand by becoming familiar with common prefixes and suffixes used
in biology. These affixes, derived from Latin and Greek roots, form the
basis for many difficult biology words.
Below is a list of a few biology words and terms that many biology students
find difficult to understand. By breaking these words down into discrete
units, even the most complex terms can be understood.
1. Autotroph
This word can be separated as follows: Auto - troph.
Auto - means self, troph - means nourish. Autotrophs are organisms
capable of self nourishment.
2. Cytokinesis
This word can be separated as follows: Cyto - kinesis.
Cyto - means cell, kinesis - means movement. Cytokinesis refers to the
movement of the cytoplasm that produces distinct daughter cells during
cell division.
3. Eukaryote
This word can be separated as follows: Eu - karyo - te.
Eu - means true, karyo - means nucleus. A eukaryote is an organism whose
cells contain a "true" membrane bound nucleus.
4. Heterozygous
This word can be separated as follows: Hetero - zyg - ous.
Hetero - means different, zyg - means yolk or union, ous - means
characterized by or full of. Heterozygous refers to a union characterized by
the joining of two different alleles for a given trait.
5. Hydrophilic
This word can be separated as follows: Hydro - philic.
Hydro - refers to water, philic - means love. Hydrophilic means water-
loving.
6. Oligosaccharide
This word can be separated as follows: Oligo - saccharide.
Oligo - means few or little, saccharide - means sugar. An oligosaccharide is
a carbohydrate that contains a small number of component sugars.
7. Osteoblast
This word can be separated as follows: Osteo - blast.
Osteo - means bone, blast - means bud or germ (early form of an
organism). An osteoblast is a cell from which bone is derived.
8. Tegmentum
This word can be separated as follows: Teg - ment - um.
Teg - means cover, ment - refers to mind or brain. The tegmentum is the
bundle of fibers that cover the brain.
Pneumonoultramicroscopicsilicovolcanoconiosis
Yes, this is an actual word. What does it mean? Biology can be filled with
words that sometimes seem incomprehensible. By "dissecting" these words
into discrete units, even the most complex terms can be understood. To
demonstrate this concept, let's begin by performing biology word
dissections on the word above.
To perform our biology word dissection, we'll need to proceed carefully.
First, we come to the prefix (pneu-), or (pneumo-) which means lung. Next,
is ultra, meaning extreme, and microscopic, meaning small. Now we come
to (silico-), which refers to silicon, and (volcano-) which refers to the
mineral particles that make up a volcano. Then we have (coni-), a
derivative of the Greek word konis meaning dust. Finally, we have the
suffix (-osis) which means affected with. Now lets rebuild what we have
dissected:
Considering the prefix (pneumo-) and the suffix (-osis), we can determine
that the lungs are affected with something. But what? Breaking down the
rest of the terms we get extremely small (ultramicroscopic) silicon (silico-)
and volcanic (volcano-) dust (coni-) particles. Thus,
pneumonoultramicroscopicsilicovolcanoconiosis is a disease of the lungs
resulting from the inhalation of very fine silicate or quartz dust. That
wasn't so difficult, now was it?
Now that we've honed our dissection skills, let's try some frequently used
biology terms. For instance:
Arthritis
(Arth-) refers to joints and (-itis) means inflammation. Arthritis is the
inflammation of a joint(s).
