PRAKTIKUM MIKROBIOLOGI DASAR 2024. ACARA VI MORFOLOGI JAMUR

Summary

This script outlines a basic microbiology lab session focused on the morphology of fungi. It introduces the concept of observing the structure of unicellular and multicellular fungi, such as yeast and molds, under a microscope. The session includes identifying the differences in their morphology, observing the growth patterns, and recognizing the spores' shapes and colors. The practical steps involve preparing a slide with fungi in water, examining them at various magnifications, and correlating the lab observations with theoretical knowledge about fungi.

Q & A

What is the main topic of the video script?

The main topic of the video script is a practical laboratory session on the morphology of fungi.

What types of fungi are mentioned in the script?

The script mentions unicellular fungi like yeast (sarung SS) and multicellular fungi such as Aspergillus.

What is the difference between unicellular and multicellular fungi as described in the script?

Unicellular fungi consist of a single cell, while multicellular fungi have differentiated cells and structures, forming more complex organisms.

What is the purpose of using aquades in the laboratory procedure described?

Aquades is used to wet the center of the object glass, preparing it for the placement of fungal samples.

What tool is used to pick up the fungal sample for observation under the microscope?

A cover slip is used to pick up the fungal sample and place it on the wetted object glass.

Why is it important to avoid air bubbles in the preparation of the sample?

Air bubbles can interfere with the observation of the fungal morphology under the microscope, leading to inaccurate results.

What magnifications are suggested for observing the morphology of the fungi?

The script suggests starting with a low magnification of 10x and then moving to a higher magnification of 40x for detailed observation.

What are the characteristics of Aspergillus mentioned in the script?

Aspergillus is mentioned as a multicellular fungus with a distinct appearance, including the production of spores.

What is the significance of observing the spores of fungi?

Observing the spores helps in identifying the type of fungi, as they can vary in shape, size, and color.

What does the script imply about the color changes in fungi?

The script implies that color changes in fungi can indicate different stages of growth or the presence of certain species, such as in the case of moldy bread.

What is the final step suggested in the laboratory procedure for observing fungi?

The final step is to observe the parts of the fungi that are visible under the microscope and to draw them on a piece of paper.
