text: Development of these structures results from asymmetric cell division after SPCH production is inhibited by YODA.
full_question: Development of these structures results from asymmetric cell division after SPCH production is inhibited by YODA. In response to elevated carbon dioxide levels, an increase in the number of these structures has been observed to be regulated by the HIC gene. The pericytic type found in ferns are surrounded by a single donut-like cell, while monocots possess two peripheral lens-like cells in the gramineous type. Uptake of potassium ions increases turgor pressure within these structures causing them to swell and open. Flanked by two guard cells, for 10 points, name these pores found on the surfaces of plant leaves.
