Abstract

Stomata are pores on specialized epidermal cells of plant leaves that facilitate photosynthesis and water transport. This research using geraniums, seeks to determine if stomata densities vary among developing and mature leaves. Epidermal leaf impressions were taken and stomata densities were calculated. Developing leaves were found to average 7.75 ± 0.79 and mature leaves 5.65 ± 0.44. This was found to be statistically significant and is thought to be a result of the maximization of growth potential by developing leaves balanced by a need to regulate water loss by mature leaves.
