Microscope Slide Preparation Techniques

This video tutorial guides students through the process of preparing and viewing Alodia and cheek cell slides using a microscope. It emphasizes safety precautions, such as wearing goggles, and provides detailed steps for slide preparation and microscope usage. Students learn to focus the microscope and observe cell structures, enhancing their understanding of microscopic examination.

Why is it important to wear safety goggles during the lab?

• To look stylish

• To protect eyes from chemicals

• To see better

• To avoid distractions

What is the first step in preparing the Alodia slide?

• Cut the Alodia plant

• Use methylene blue

• Add a drop of water to the slide

• Place the leaf directly on the slide

How should the cover slip be placed on the Alodia slide?

• Drop it straight down

• Press it firmly

• Slide it from the side

• Place it at a 45° angle

What should you do if the Alodia slide is not in focus?

• Turn off the microscope

• Adjust the coarse adjustment knob

• Increase the light intensity

• Remove the slide

What is used to stain the cheek cells?

• Iodine

• Methylene blue

• Water

• Ethanol

How should you collect cheek cells for the slide?

• Use a pipet

• Scrape with a knife

• Rub a toothpick inside your cheek

• Use a cotton swab

What should you do with the toothpick after collecting cheek cells?

• Leave it on the desk

• Wash it and keep it

• Throw it in the garbage

• Reuse it

Before mounting the cheek cell slide, what power should the microscope be on?

• Off

• Low power

• High power

• Medium power

What should you do after finishing with the microscope slides?

• Store them in a drawer

• Clean them at the sinks

• Throw them away

• Leave them on the desk

What is the final step after observing the cheek cell slide?

• Turn the microscope to high power

• Adjust the light intensity

• Remove the slide and clean it

• Turn the microscope to low power
