It’s Monday again. Biology Practical Class for me. I’ve taken some picture of my failed experiment, darn, I’m sucks at this. Haha.
My personal Microscope
Slides that I've prepared
Onion Epidermis Cells, that's what I got when I look into the Microscope
This experiment is to test the degree of plasmolysis of the onion cells when you soak them in different concentration of sucrose solution, but sadly for me, I don’t know what happen, my onion cells all look exactly the same in every concentration, so I’ve got no results. What a bad day for me.
Same Cells under X40 magnification
The two previous picture was soaked in distilled water, and this, soaked in 0.5mol per dm cube concentration, is suppose to have slight plasmolysis, but, LOL, no difference. So no results for me, even my very pretty Biology Teacher can’t find anything to help me, she said, I didn’t give enough time for it to be soaked in the solution.
Darn, I don't see any plasmolysis
WTH, do u guys see any difference?
And so I become very Emo. Why I so useless neh? I’ve never done anything good in Biology Practical Class since, I observed my Cheek Cells. It’s like a curse, I never got anything right. And my AS is going to finish soon, if i go to exams like this, I’m totally gone.
Out of bad mood, I cut all the onion into small pieces
Hee, a smart guy who always did well in Practical, may be because he is precise? Compare the things he prepared and mine...
The best I could get, the degree of plasmolysis is so Not obvious
Then it’s time for culinary art. Onion + Iodine + Methyl Orange + Sunflower Oil + Stick + Alcohol + Fire = Great Onion Dish
Nice?
I am really not too familiar with this topic but I do like to visit blogs for layout ideas and interesting topics. You actually expanded upon a subject that I usually don’t care much about and made it very fascinating. This is a memorable blog that I will take note of. I already bookmarked it for future reference. Thank you
dispenses use a terrific web site decent Gives thanks for the effort to assist me personally
This is a good step to save paper. And will save the rain forests in Indonesia. Moreover, this will reduce the burden on the back of elementary school students. Of course this will make the traditional printing companies and governments in the third world into a panic because of their unpreparedness of information technology. . .
Easily, the post is actually the greatest on this deserving topic. I agree with your conclusions and will thirstily look forward to your coming updates. . . . .
