My Biology Glossary

20 terms

Hi, my name is Léanne Plante. I live in Blainville. I have been studying Natural Science for one and a half years and my favorite subject is biology. The glossary that I made could be useful for the students that are already studying biology and also for everyone who is interested in that subject and who wants to learn more about the terms that we use in that field. The words that we find in this glossary are relevant to the basic notion of biology. They are terms that are often use in that field and learning their meaning could help students to have a better understanding of this field of study.
