Lab 3: Aseptic Technique & Bacterial Cell Morphology

This set of flashcards covers key vocabulary and concepts related to aseptic techniques and bacterial morphology as discussed in Lab 3.

Aseptic technique

A method used in laboratories to prevent contamination of cultures and sterile materials.

Colony characteristics

Features of a bacterial colony that help in identifying the specific organism.

Isolated colony

A single, distinct growth of bacteria that can be analyzed separately.

Colony shape

The overall form of a bacterial colony, such as circular, irregular, or filamentous.

Colony margin

The edge or border of a bacterial colony, which can be entire, undulate, or lobate.

Colony elevation

The height of a bacterial colony compared to the agar surface, such as flat or raised.

Filiform growth

A type of bacterial growth that appears thread-like on an agar slant.

Water soluble pigment

Pigments produced by some bacteria that dissolve in water; not all bacteria produce pigment.

Agar slant

A solid medium in a test tube used for bacterial culture, providing a greater surface area for growth.

Concentric growth

A growth pattern of bacteria that forms a swarming appearance on agar.
