Terminology Guide — The Construction Kit

Reference

v0.1 · Page 1 of 2

Biology vocabulary is not a random pile of words to be hauled into memory one at a time — it is a construction kit. Nearly every technical term is built from a small set of Greek and Latin roots snapped together like parts. Know that cyto- means cell and -kinesis means movement, and cytokinesis announces itself. Memorizing words is linear; learning roots is exponential — thirty roots unlock several hundred words.

The habit that scales

Keep a running roots page at the back of the lab notebook; add to it every time a new prefix or suffix appears. When you hit an unfamiliar term, break it apart out loud and guess the meaning before you look it up — that small act of retrieval is what fixes the root in memory.

The core roots

Part	Meaning	Example & what it tells you
cyto- / -cyte	cell	cytoplasm, leukocyte — anything cell-related.
-lysis	breaking, splitting	glycolysis splits glucose; hydrolysis breaks with water.
homeo-	same, steady	homeostasis — keeping internal conditions stable.
auto-	self	autotroph — an organism that makes its own food.
hetero-	different, other	heterotroph — feeds on others.
photo-	light	photosynthesis — building sugar using light.
-phyll	leaf	chlorophyll — the green pigment of leaves.
chloro-	green	chloroplast — the green sugar-making body.
mito-	thread	mitosis — chromosomes look like threads.
meio-	less, fewer	meiosis — halves the chromosome number.
-ose	sugar	glucose, fructose, lactose — the “-ose” gives it away.

Part	Meaning	Example & what it tells you
-ase	enzyme	amylase, lactase, ATPase — usually acts on the “-ose” before it.
endo-	inside, within	endocytosis brings material into the cell.
exo-	outside, out	exocytosis expels material from the cell.
pro-	before, primitive	prokaryote — came before the nucleus.
eu-	true, good	eukaryote — has a “true” membrane-bound nucleus.
karyo-	nucleus, kernel	prokaryote, eukaryote — the cell’s “kernel.”
-troph / tropho-	feeding	autotroph, trophic level — feeding levels.
-genesis	origin, creation	biogenesis — the making or origin of something.
trans-	across	transport moves molecules across a membrane.
iso- / hyper- / hypo-	equal / over / under	isotonic, hypertonic, hypotonic — key to osmosis.

High-value clusters by unit

Cells — cyto-, karyo-, pro-/eu-, endo-/exo-, and the iso-/hyper-/hypo-tonic family. Turns five separate facts into one connected web.
Energy — photo-, chloro-, -phyll, glyco-, -lysis, -ose, -ase. Photosynthesis, chlorophyll, glucose, glycolysis, and ATP synthase all decode from this set.
Genetics & cell division — mito-, meio-, -genesis, trans-. The thread/reduction contrast even encodes the difference between the two divisions.
Ecology & physiology — auto-, hetero-, -troph, homeo-, trans-. The cell-unit ideas scaled up to whole systems.

How to actually use this

Don’t swallow the table in one sitting. Keep this page open during reading and lab; each time you meet an unfamiliar term, name the parts, guess the meaning, then check. Within a few weeks the “memorization class” quietly turns into a class you can read your way through.
