MTEL Biology study guide
MTEL Biology · Work through your exam, one topic at a time.
The MTEL Biology (13) is a Massachusetts Tests for Educator Licensure subject-matter test, one of the assessments the Massachusetts Department of Elementary and Secondary Education uses to confirm that candidates for PreK–grade 12 academic licenses are knowledgeable in the subject matter of the license they seek. It is aimed at prospective biology teachers who must demonstrate subject-matter competence alongside the communication and literacy requirement. The MTEL Biology study guide has 5 sections and about 1,782 words.
01Cell Biology and Biochemistry
The Cell Biology and Biochemistry subarea asks you to connect molecular structure to cellular function. Expect questions on macromolecules, enzyme kinetics, membrane transport, organelle roles, and the energy pathways of photosynthesis and respiration, plus the cell cycle.
360 words, about 2 min02Genetics and Molecular Biology
This subarea tests information flow from DNA to phenotype and the inheritance patterns that explain phenotypic ratios. Questions commonly combine replication, transcription/translation, mutation effects, meiosis, and Mendelian or non-Mendelian crosses, with some biotechnology lab reasoning.
360 words, about 2 min03Evolution and Biodiversity
Evolution and Biodiversity asks how allele frequencies change, how reproductive isolation produces species, and how organisms are classified and related. Expect Hardy–Weinberg calculations, natural selection scenarios, speciation mechanisms, and interpretation of phylogenetic trees, plus broad diversity across the three domains.
342 words, about 2 min04Human Anatomy and Physiology
This subarea tests how organ systems maintain homeostasis and how nervous, endocrine, circulatory, respiratory, digestive, excretory, immune, and reproductive structures work together. Questions often use feedback loops, transport pathways, and graph or data interpretation rather than isolated labeling.
370 words, about 2 min05Ecology
Ecology tests interactions among organisms and their environment: population growth, community interactions, energy flow, nutrient cycling, succession, and human impacts. Expect graph interpretation, food-web reasoning, and calculations involving population size or energy transfer.
