Question

Activity Take a small drop of curd or buttermilk on a clean glass slide. Dilute it with a little water. Carefully keep a coverslip. Observe it under high power of compound microscope. What did you see?

Answer 1

here are the steps for the activity:

Materials needed:

• Glass slide
• Cover slip
• Curd or buttermilk
• Water
• Dropper
• Compound microscope

Steps:

1. Take a clean glass slide and place a small drop of curd or buttermilk onto it.

2. Dilute the curd or buttermilk with a little water using a dropper. Be careful not to dilute it too much, as it may be difficult to observe under the microscope.

3. Place a cover slip carefully on top of the diluted sample. Make sure there are no air bubbles trapped underneath the cover slip.

4. Place the prepared slide on the stage of the compound microscope and secure it in place.

5. Using the high power objective lens, observe the slide under the microscope and adjust the focus as necessary.

6. You may observe different types of microorganisms such as bacteria, yeasts, and other types of cells present in the curd or buttermilk sample.

7. You may also observe the structure of these microorganisms, such as their shape, size, and movement.

8. Additionally, you may observe the presence of curd or buttermilk particles and other debris in the sample.

Observations may vary depending on the sample and the microscope used. However, this activity can provide a glimpse into the microscopic world and the different types of microorganisms present in everyday items like curd or buttermilk
