The image above is of the edge of a leaf from a coriander plant, observed under foldscope. In the picture, we can see clearly a transparent vein going across the field of vision. Cells, green due to their chloroplast, are aligned with clear organization within lanes. Notice that the greeness is not distributed evenly within all cells.

The sample is obtained from a Coriander plant in Ricketts Hovse, around 4:30 PM, 5/29. The leaf is plucked and the edge is taken with a pair of tweezers. We chose to observe the edge of the leaf as it’s thinner than the interior and thus of less layers of cells.

Coriander, also known as Chinese parsley, is a herb whose stems and leaves are usually called cilantro. I personally do not appreciate either the taste or scent of cilantro, yet the observation was interesting. More information can be found at this Wikipedia page: https://en.wikipedia.org/wiki/Coriander .

This observations is done in cooperation with Aru Mukherjea. Thanks Aru!
