Stromules tend to be relatively rare in cell types such as mesophyll or guard cells that contain large chloroplasts. |
Asymmetric divisions lead to the formation of a pair of reniform guard cells surrounding the stomatal opening. |
The concavo-concave shape of the anticlinal cell walls adjacent to the guard cells, reflects the bowed shape of the guard cells. |
It was concluded that stomatal conductance is not directly determined by the photosynthetic capacity of guard cells or the leaf mesophyll. |
The genotype of the epidermal layers were determined by examining the chlorplast containing guard cells. |
The blue light response of guard cells is mediated by the chloroplastic carotenoid, zeaxanthin. |
