Usage: Often used with the preposition 'between' or 'from'.

### 2. cell development

noun · CEFR C1 · Technical

the process where young cells change to become a specific type, like a blood cell or a bone cell.

For teachers: the process by which less specialized cells become more specialized in structure and function during the development of a multicellular organism.

- Stem cells are famous because they can undergo differentiation into many different types of tissue.
- During embryonic development, cellular differentiation is governed by complex genetic signals that determine the ultimate fate of each cell lineage.

Usage: Uncountable when referring to the general biological process.

### 3. calculating derivatives

noun · CEFR C2 · Technical

a way of measuring how a function changes at a specific point.

For teachers: the mathematical operation of finding the derivative of a function.

- In our calculus class, we learned the rules for the differentiation of basic functions.

Usage: The inverse process is known as integration.

### 4. separation of magma

noun · CEFR C2 · Technical

For teachers: the process by which different igneous rocks are formed from a single parent magma as it cools and minerals crystallize.

- Magmatic differentiation explains why we find different minerals in various layers of the earth.
