Epidermis of a Croton leaf

on

I, along with my fellow students of CMR National PU College at ITPL, Bangalore, observed the epidermis of a Croton leaf on 8th June, 2018. The leaf used for the observation was that of a croton found in my garden. Care was taken to ensure that we use the epidermis from the part of the leaf that was completely non-green, ie. violet, in order to ascertain if green (chlorophyll-rich) cells would be found in these regions.

As seen in the image above, the red and violet coloured cells that were dispersed among the green chlorophyll-rich cells were clearly distinguishable. Although the cells themselves could not be viewed with a greater level of magnification due to the limitations of using a foldscope, the image obtained was still remarkable and could be used to come to the conclusion that coloured cells are always found among green cells.
