Indicate which of the following observations can be made when observing growth on nutrient agar. Group of answer choices Gram reaction of growth Acid-fast morphology Amount of growth Opacity/clarity of colonies Color of colonies Presence or absence of endospores Shape and /or pattern of growth

Respuesta :

Answer:

Amount of growth

Opacity/clarity of colonies

Color of colonies

Shape and /or pattern of growth

Explanation:

An agar plate is a Petri dish containing agar as a solid growth medium supplied with nutrients (i.e., an enriched medium), which enable to culture different microbes ranging from fungi to bacteria. Colony morphology is a widely used approach to describe the unique features of bacteria colonies growing on agar media. These colony features include, among others, shape (round, circular, punctiform, irregular), elevations/depressions (convex, concave, flat), textures (dry, moist, crusty, dull, shiny, mucoid, friable, rough), colors (cream, white, purple, gray, red, green, yellow, blue), etc.

The observation that could be made regarding the growth over nutrient agar would be:

C). Amount of growth

D). Opacity/clarity of colonies

E). Color of colonies

G). Shape and/or pattern of growth.

Observation

  • The growth of nutrient agar can be observed in above-mentioned ways.
  • The area covered during the growth, the level of clarity amongst them, the color developed by them, and their size and formation as well.
  • This assists in making worthy deductions about them.
  • Thus, options C, D, E, and G are the correct answers.
