What Is Stomatal Density? Stomatal density refers to the number of stomata present on plant leaves per square millimeter. Leaf stomata are small pores that facilitate gas exchange in plants. PDF | Dioscorea alata L. has three stomatal complex types, namely, paracytic, anisocytic, and tetracytic stomata, with percentage frequency values of 50, 18, and 32, respectively. Dioscorea. All species showed low stomatal transpiration rates ( × 10 −5 – × 10 −3 mol m −2 sec −1) and there was no evidence for stomatal density as a factor. In addition to paracytic stomata, other stomatal types observed include hemi-paracytic in C. paradisi, brachy-paracytic in C. reticulata and .

hemiparacytic stomata are bordered by just one subsidiary cell that differs from the surrounding epidermis cells, its length parallel to the stoma opening. This type occurs for instance in the Molluginaceae and Aizoaceae. paracytic (meaning parallel celled) stomata have one or more subsidiary cells parallel to .

Dioscorea. impressions of leaf stomata to generate and test an hypothesis of their choice about how leaf stomata density might vary under different environmental conditions. First, students learn how stomata density affects leaf carbon, water, heat budgets, and photosynthesis. Then, students design their own study to . O. regia has more stomata on its adaxial surface than abaxial (hypoamphistomatic), tetracytic stomata, large stomata and high stomatal density transpired at faster rate (×10 -5 mol/m 2 /s) and humidifies the atmosphere faster than C. nucifera with paracytic stomata which were restricted to adaxial surface. All species showed low stomatal transpiration rates ( × 10 −5 – × 10 −3 mol m −2 sec −1) and there was no evidence for stomatal density as a factor.
