Greek & Latin Roots for Biology

Biological Terminology (Bio Terms): Latin & Greek Word Parts (Prefixes, Root Words, and Suffixes)
Biology students are faced with the challenge of learning a large number of new terms predominately based on the Latin and Greek languages.
Therefore, students should learn to recognize word parts since they often give clues as to the meaning of a word. Research suggests that students
knowledgeable of these terms score significantly higher on standardized tests (EOC, ACT, & PSAT). During the summer, all Biology students must
create study cards of the following word parts and learn them during the summer months. All students will be quizzed on the following terms during the
first full week of school and throughout the school year.

unab-, efad-, af-

The best way to study the bio terms is to read (silently & out loud) through your cards both term-first and definition-first so that can you get used to remembering
both ways. Go through the entire stack MULTIPLE times day and night. During concentrated study times, go through the cards a first time and place all of the
cards answered wrong in a separate pile. Go through the pile of wrongly answered cards, and again place all the cards answered incorrectly in a separate pile.
Keep going through the “wrong” pile until there aren’t any cards left that you can’t answer. Repeat this process from the beginning until you are able to go through
the entire stack of bio terms without missing any. Give the terms to another person and have them quiz you. If you are able to answer 95% of them right – then
CELEBRATE and sleep on it. Review the stack at least 3x’s a week to integrate the terms into long term memory.
