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).
Erythrocyte
(Erythro-) means red and (-cyte) means cell. Erythrocytes are red blood cells.
Okay, let's move on to more difficult words. For instance:
Electroencephalogram
Dissecting, we have (electro-), pertaining to electricity, (encephal-)
meaning brain, and (-gram) meaning record. Together we have an electric
brain record or EEG. Thus, we have a record of brain wave activity using
electrical contacts.
Schizophrenia
Individuals with this disorder suffer from delusions and hallucinations. (Schis-) means split and (phren-) means mind.
Thermoacidophiles
These are ancient bacteria that live in extremely hot and acidic
environments. (Therm-) means heat, next you have (-acid), and finally
(phil-) means love. Together we have heat and acid lovers.
Once you understand the commonly used prefixes and suffixes, obtuse
words are a piece of cake! Now that you know how to apply the word
dissection technique, I'm sure you'll be able to determine the meaning
of the word thigmotropism (thigmo - tropism).
