Biology Lab Quiz Flashcards

Flashcards based on key concepts related to microbiology and protozoa from biology lab.

Colony

A visible group of microorganisms that grew from a single cell or small group of cells.

Aseptic technique

Procedures used to prevent contamination by unwanted microorganisms.

Nosocomial infection

An infection acquired in a healthcare setting.

Healthcare-associated infection (HAI)

An infection acquired while receiving medical care.

Importance of Aseptic technique

Prevents the spread of bacteria and reduces infection risk.

BHI agar

Brain Heart Infusion agar used to grow many types of bacteria.

Nutrient Agar (NA)

Used for growing environmental bacteria.

SDA agar

Used for growing fungi such as yeast and molds.

Incubating plates upside down

To prevent condensation from dripping onto the agar.

Day 2 counts

Total colonies and number of different colony types.

Nucleus

Contains DNA and controls all cell activities.

Cytoplasm

Jelly-like material inside the cell.

Food vacuole

A membrane-bound sac where food is digested.

Chloroplast

An organelle that performs photosynthesis.

Eyespot (stigma)

A light-sensitive structure that helps detect light.

Pseudopodia

Temporary extensions used for movement and engulfing food.

Cilia

Short hair-like structures used for movement.

Flagellum

A long whip-like structure used for movement.

Protozoan using pseudopodia

Amoeba.

Protozoan using cilia

Paramecium.

Protozoan using flagellum

Euglena.

Euglena's capability

Can photosynthesize because it has chloroplasts.
