Answer:
To ensure uniformity during streaking of the gel surface and to also prevent contamination while picking up the spores.
Step-by-step explanation:
When preparing a fungi slide, several materials are used to prepare a slide that serves the purpose. Good aseptic procedures should be followed so as to prevent contamination of the culture. Inoculating needles are used in the preparation of the slide, and they are helpful in achieving good aseptic techniques. These needles consist of the loop and needle ends.
The loop end is used in streaking the spores uniformly on the gel surface while the needle end is used in extracting the fungal colonies. Before the loop end is used, it undergoes flaming and cooling to ensure that microorganisms are killed. In so doing, contamination is also prevented.
