Leaf mesophyll cells

Ocimum basilicum L. seedlings were exposed to diff erent concentrations of Cr (0-8 mg L-1 of Cr3+) to evaluate the cellular localisation of chromium, plant accumulating capacity, and potential cellular defence mechanisms against Cr stress.

In the present study, the protective effect of nitric oxide (NO) against Cd-induced structural disturbances in pea (Pisum sativum) leaves was investigated. Cadmium treatment resulted in a decreased leaf size and thickness of the lamina, reduced intercellular spaces in the mesophyll, small pavement cells, and a high density of stomata.

This is due to the fact that in green leaves, the chlorophylls and carotenoids have a broad absorption band in the 400-500 nm spectral region and blue light does not penetrate very deeply into the leaf tissue, and as a result the fluorescence associated to blue light excitation is mainly generated in the green mesophyll cells close to the leaf`s surface, therefore little absorption occurs.
