Into the microscope

Once, again it's time to enter the biology laboratory. Today, we used the microscope to view eukaryotic cells which are from the onion, potato, moss, cheek, fir and the liver. Ivan went with Giju to buy some panadol as Ivan was having a headache. They came in a few minutes after the lecturer started giving instructions. Well, as usual, biology class was happening. Wohoo!


The moss

After the lecturer's long instructions, we were given the go. First up was to peel off the onion epidermis layer. It was relatively easy. Then, I placed the epidermis on a glass slide and dropped a few drops of iodine onto the epidermis. After that, the slide was placed in the microscope and viewed. Preparing the potato slide was quite a challenge as we had to cut very thin strips from it. However, my first attempt was successful and I did not need to redo the slide.


The onion and potato

After the onion and the potato, everyone took some moss and fir sample to be viewed under the microscope. No iodine was needed this time. Only deionized water. The lecturer claims that we could actually see the chloroplast but I did not manage to spot them. Sad. Moving on, everyone viewed the liver slide after that. We could only see the nucleus and the plasma membrane. Gah. The highlight of today's experiment was obtaining the cheek cell. We had to donate some of our own cells to view them. Gosh, Ivan swabbed his cheek with the earbud but nothing could be seen under the microscope. I tried swabbing my cheek with the earbud too and could see nothing. I asked toothpicks from the lab assitant and tried to obtain some cheek cells. That failed too. Therefore, the lecturer omitted that cheek cell. Alright, I'll intro my biology classmates and also the lecturer to you readers =). Enjoy the eye candies.

Miss Irene

Well, this is Ms. Irene. She's a good lecturer even though she loves to torture us with many assignments and quizzes. Well, she easy to talk to and we can joke with her as well as "teasing" her. We just found out more about her today. It's confidential! Hopefully whatever she does to us during all four semesters have good intentions. *fingers crossed*

If you're wondering why there are only eleven people when I metioned that there were twelve in the previous post, it's because Mr. Kah Yew dropped biology. Rest in peace. We will always remember you.
