Question

What distinguishes a defined medium from an undefined medium?
Options
A Defined medium has known quantities of all ingredients
Correct Answer
B Undefined medium is only used for eukaryotic cells
C Defined medium is more expensive than undefined medium
D Defined medium contains complex ingredients like yeast extract
Correct Answer

Option A is the correct answer.

Detailed Explanation

A defined (synthetic) medium is characterized by having all of its chemical components and their exact concentrations precisely known. In contrast, an undefined (complex) medium contains components of biological origin (e.g., yeast extract, peptone, blood) whose exact chemical composition and quantities are not precisely known.

Hint

The name 'defined' itself gives a strong clue about the nature of its ingredients.
