DNA extracted from peas
Looks like the moon on a dark night? Well yeah, but actually, it’s not. It’s a picture of green peas DNA that I took during our Cell Biology class (third year first semester). It was viewed under a Compound Light Microscope’s High Power Objective with a magnification of 1,250x. This was extracted by my classmates Poll and Jencel. I and Chai was not able to extract a whole DNA but damaged ones instead.
Human Cheek Cell
My cheek cell actually. Viewed under a Compound Light Microscope. High Power Objective.
Magnification of 1,250x. Stained by Methylene Blue. Nucleus visible as a dark circle at the center.
Stomata of San Francisco Leaf

Extracts from various leaves
The leaves were pounded and extracted into test tubes.
Paper Chromatography
This was an activity we performed for Organic Chemistry. The purpose of this experiment was to separate the pigments in a plant extract.
That is a very good tip particularly to those fresh to the
blogosphere. Simple but very precise info… Thank you for sharing this one.
A must read article!
